HCI

by

As IT professionals seek VMware alternatives, they often encounter hyperconverged infrastructure (HCI) solutions, but these systems can’t deliver the media and node flexibility of Ultraconverged Infrastructure (UCI). UCI solutions like VergeIO provide businesses with enhanced adaptability to support diverse storage media and node types. This approach better aligns with real-world demands and long-term infrastructure goals.

What is Ultraconverged Infrastructure?

Unlike traditional HCI or three-tier architectures, UCI integrates storage and networking directly into the hypervisor, running as services rather than virtual machines (VMs). Traditional three-tier systems rely on separate networking, virtualization, and storage hardware components. At the same time, HCI typically bundles these functions but still operates them as independent layers, each running as independent VMs.

With UCI, these critical functions are embedded within the hypervisor, improving efficiency and higher performance. This architectural shift also delivers greater flexibility in choosing media and server (node) types, allowing IT teams to scale infrastructure resources precisely according to their specific workload demands. VergeIO’s implementation of UCI is VergeOS.

The Limitations of Traditional HCI in Mixing Media and Node Types

Traditional hyperconverged infrastructures have rigid configurations requiring identical nodes for computing and storage. Organizations must scale both resources equally, which may not meet their needs. Additionally, traditional HCI solutions can’t support multiple storage types in the same environment, like flash and HDDs. These limitations force businesses to overprovision resources and spend unnecessarily on high-performance storage not aligned with their workloads.

Ultraconverged Infrastructure (UCI) addresses these challenges by enabling independent scaling of compute and storage through a mixed-node approach. It supports various storage media types, allowing IT teams to use high-density QLC flash, high-endurance TLC flash, and HDDs for optimized performance. This flexibility lets organizations assign workloads to the best resources for cost efficiency and improved performance.

Comparing HCI and UCI

The following table summarizes key differences between HCI and UCI, emphasizing how UCI overcomes many of the limitations faced by traditional HCI:

FeatureHyperconverged Infrastructure (HCI)Ultraconverged Infrastructure (UCI)
Node FlexibilityRequires identical nodes with balanced compute and storage resourcesSupports mixed nodes (compute-heavy, storage-heavy, GPU-heavy), allowing independent scaling

Hardware RefreshAll servers must be refreshed at onceServers can be refreshed gradually, one at a time, as needs change

Leveraging Mixed Storage Media: TLC, QLC, and HDDs

The Media and Node Flexibility of Ultraconverged

A key strength of UCI is its ability to support a variety of storage media, including TLC (Triple-Level Cell) flash, QLC (Quad-Level Cell) flash, and traditional HDDs. Each storage type offers unique benefits, and UCI enables IT teams to assign workloads to the most appropriate media, optimizing cost and performance without compromise.

  • TLC NVMe Flash: High-performance, high-endurance TLC flash is ideal for applications requiring frequent access to data, such as real-time analytics or transactional databases. UCI platforms allocate TLC flash where speed is critical.
  • QLC NVMe Flash: Cost-effective and high-density, QLC flash can store large datasets with minimal expense. QLC media, like Solidigm’s new 60TB+ QLC drives, is optimal for workloads with significant storage needs but lower performance requirements.
  • HDDs: HDDs remain a cost-effective choice for archival storage and backup, as they offer high capacity without the expense of flash storage. UCI allows organizations to assign archival or backup data to HDDs, reducing costs and freeing up flash resources for more demanding tasks.

In a recent evaluation, StorageReview verified VergeOS’s multi-media support, showcasing its flexibility to handle diverse storage types within a single environment. Readers can watch our on-demand webinar, in which VergeIO, StorageReview, and Solidigm discuss the test results and how these media options enhance the platform’s performance.

Scaling Storage and Compute Independently with Mixed Node Types

UCI supports mixed node types, enabling independent scaling of compute and storage resources. Traditional HCI solutions require identical nodes for expansion, which is inefficient for businesses with unequal compute and storage demands. For example, data-intensive applications may need more storage without extra compute, whereas HPC tasks might require more compute with less storage.

The Media and Node Flexibility of Ultraconverged

In UCI, storage-heavy nodes or compute-heavy nodes can be added independently within the same instance, enabling organizations to scale up only what they need. This flexibility offers significant advantages for specific workloads:

  • Data Lakes and Analytics: Storage-heavy nodes provide the capacity required for large data lakes, while compute-heavy nodes and GPU-heavy nodes can seamlessly access the storage, creating a powerful path to analytics, machine learning (ML), and AI workloads—all supported by the media and node flexibility of Ultraconverged Infrastructure (UCI).
  • Virtual Desktop Infrastructure (VDI): Compute-heavy nodes can handle the CPU resources needed for VDI. In contrast, fewer storage-heavy nodes are used for backend storage, ensuring cost-effective scaling without excess.
  • Backup and Archival: Storage-heavy nodes offer the necessary space for long-term backup and archival data without requiring additional compute resources. When paired with GPU-heavy nodes, this configuration provides a high-capacity, cost-efficient foundation supporting AI-driven data analysis or data mining when needed.

This combination of mixed nodes enables organizations to flexibly support a wide range of workloads, from storage-intensive tasks to GPU-powered analytics and AI applications, all while optimizing resource use and reducing overprovisioning.

ioOptimize: Maximizing Efficiency in Mixed-Node and Mixed-Media Environments

In VergeIO’s UCI implementation, VergeFS boosts efficiency by allowing data to be placed across various media and optimizing computing and storage use. IT can allocate performance-critical data to TLC flash and assign archival data to QLC flash or HDDs. Additionally, IT can direct high-performance workloads to compute-heavy nodes, freeing storage-heavy nodes for data-intensive applications. This management prevents resource bottlenecks and maximizes ROI throughout the infrastructure.

The Advantages of UCI’s Flexibility in Media and Node Types

Combining mixed storage media and mixed node types allows UCI to deliver several essential benefits for modern data centers:

  1. Cost Efficiency: Organizations can optimize storage costs by matching storage media to workload requirements without compromising performance. High-density QLC and HDDs help reduce expenses, while high-performance TLC flash is allocated to applications that truly need it.
  2. Scalability: Mixed node types allow organizations to scale only the resources they need, adding storage or compute independently for greater scalability and control over infrastructure growth.
  3. Enhanced Flexibility: The media and node flexibility of Ultraconverged Infrastructure (UCI) allows businesses to fine-tune infrastructure according to specific workload requirements, reducing waste and maximizing resource utilization.
  4. Future-Proofing: UCI supports a broad range of storage and compute configurations, allowing businesses to adopt new storage technologies and accommodate changing needs over time, ensuring the infrastructure remains resilient and adaptable.

Conclusion: Ultraconverged Infrastructure for True Flexibility and Efficiency

Flexibility is essential in today’s complex IT landscape. Ultraconverged Infrastructure (UCI) provides media and node flexibility unmatched by traditional HCI, supporting high-performance TLC flash, high-capacity QLC flash, and cost-effective HDDs. UCI allows businesses to mix compute-heavy and storage-heavy nodes, scaling resources to meet real-world demands and reduce costs.

Data centers have come a long way since the early days of server infrastructure, but one question remains: Why do most data centers still rely on dual-processor servers with 16 or 32 cores despite the availability of quad-processor servers? Quad-processor systems, after all, offer significant advantages like reduced server count, lower total costs, and decreased power and cooling requirements. Yet, many organizations must forgo these benefits.

This article explores the historical context of quad-processor servers, the real reasons behind their limited adoption, and why modern virtualization solutions are required to help organizations fully unlock the potential of these powerful machines.

The History of Quad-Processor Servers

Quad-processor servers have existed for over twenty years. Intel first offered quad-processor server support with its Xeon MP processors in the early 2000s. Designed for high-performance workloads, these servers provide notable benefits in computing power, minimized server footprint, and efficiency. Theoretically, they should have represented a straightforward option for data centers looking to streamline their infrastructure and lower operating costs.

However, despite these early promises, the adoption of quad-processor servers has remained limited.

Why Haven’t Quad-Processor Servers Taken Off?

At first glance, the main reason organizations might avoid quad-processor servers seems to be cost. However, a closer look reveals that hardware cost is not the primary barrier. In fact, when you account for fewer servers, reduced energy consumption, and lower cooling requirements, quad-processor systems result in a lower total cost of ownership compared to the cost of delivering the same compute capacity using dual-processor servers.

So, why do data centers still rely on dual processor servers? The answer lies in inefficient virtualization software and licensing models.

1. Inability to Fully Utilize Additional Compute and Storage Capacity

A key challenge lies in virtualization solutions’ storage and compute utilization capabilities. Even when quad-processor servers are deployed, many virtualization platforms struggle to effectively distribute workloads across the increased number of cores and more densely packed storage.

Virtualization solutions were initially designed around smaller dual-processor servers. These architectures are not inherently optimized to take full advantage of the increased computing power and memory that quad-processor systems offer. As a result, these systems often bog down, forcing IT teams to reconfigure environments to extract performance gains manually.

2. Virtualization Solutions Aren’t Optimized for Scaling Down

Why Do Data Centers Still Rely on Dual Processor Servers
Lack of Affordable Quad-Processor Support = Server Sprawl

If the virtualization software can efficiently use them, quad-processor servers should lead to fewer physical servers, and the data center should actually shrink in size. Another reason why data centers still rely on dual-processor servers is that traditional virtualization solutions don’t have an easy way to scale down, making refreshing to fewer, more powerful servers very complex. The result is server sprawl, which is the opposite of sustainability.

3. The Licensing Problem: Software Costs Outpacing Hardware Savings

Perhaps the most significant reason why data centers still rely on dual-processor servers is how most virtualization software is licensed. Most major virtualization platforms, including VMware, have adopted licensing models based on the number of CPU cores. This strategy effectively makes the software cost significantly more expensive than the hardware costs when moving from dual-processor to quad-processor servers.

As a result, the software cost cancels out any potential savings from reduced hardware, power, and cooling expenses. This dynamic leaves many organizations feeling trapped, unable to justify the transition to quad-processor systems despite their clear benefits.

Part of the issue is that legacy virtualization solutions often hide their inefficiencies by requiring customers to maintain more physical servers in a cluster than their compute demands truly justify. These platforms spread workloads across an unnecessarily large number of servers, compensating for their inefficiencies. When introducing a quad-processor server, which should theoretically allow for fewer servers, these inefficiencies become even more exposed.

Traditional licensing strategies often hide these inefficiencies behind twice as many servers as the customer needs. In this scenario, virtualization vendors profit from increased server counts and core-based licensing, while customers are left with an infrastructure that is neither fully optimized nor cost-efficient.

VergeIO and ioOptimize: A Common-Sense Approach to Virtualization

To truly take advantage of today’s powerful servers, organizations need a virtualization solution designed to optimize performance across dual—and quad-processor environments. This is especially important for environments in transition, where a mix of dual—and quad-processor servers may exist.

Server Based Licensing

VergeIO offers a server-based licensing model, meaning organizations are not penalized for using more powerful hardware. Whether your infrastructure includes dual or quad-processor systems, VergeIO scales seamlessly across both, helping you maximize your resources without the bloated costs associated with core-based licensing.

What sets VergeIO apart is ioOptimize, which uses AI and machine learning to dynamically manage workloads, ensuring that your environment operates at peak efficiency. VergeIO’s built-in intelligence can adjust resource allocation in real-time, optimizing both computing and storage for the hardware available, whether running dual-processor or quad-processor servers. This adaptability helps organizations achieve better performance while keeping infrastructure streamlined. It also enables you to “sweat the asset” instead of replacing it, creating a situation that may make you less inclined to go to the cloud.

Scale-Down

Why Do Data Centers Still Rely on Dual Processor Servers

One of the most powerful capabilities of ioOptimize is its autonomous scale-down feature. For instance, a customer operating 12 dual-processor servers can replace them with quad-processor servers simultaneously or incrementally. ioOptimize will intelligently consolidate both VMs and storage, migrating them to the denser, more robust architecture. This process occurs automatically, requiring minimal administrative oversight. The system continuously reallocates workloads and resources, ensuring that the transition maximizes performance while reducing the number of servers. As a result, customers can reduce power consumption, cooling requirements, and data center space without interrupting operations.

The Common-Sense Solution for Modern Data Centers

With a practical focus on eliminating inefficiencies and leveraging modern hardware, VergeIO provides a clear path for data centers looking to optimize their infrastructure. The ability to fully take advantage of dual and quad-processor servers simultaneously—along with AI-driven management through ioOptimize and intelligent storage optimization—enables a scalable, cost-efficient solution that grows with your infrastructure needs.

Whether you’re looking to reduce your server count, lower your energy costs, or simply get more out of your existing hardware, VergeIO provides the flexibility, intelligence, and efficiency that today’s data centers need.

Conclusion

While quad-processor servers have been available for years, the natural barriers to their adoption have not been hardware costs but rather the inefficiencies and licensing models of legacy virtualization solutions. By leveraging AI, machine learning, and flexible, server-based licensing, VergeIO enables organizations to manage dual and quad-processor environments efficiently, taking full advantage of today’s most robust hardware.

Many IT professionals are considering alternatives to VMware to reduce licensing costs, but the sustainability benefits of efficient infrastructure software as it replaces VMware should not be overlooked. Infrastructure software that integrates storage services, server virtualization, and network services into a single code base can improve power and cooling costs, as well as resource utilization, to enable organizations to meet sustainability goals.

the sustainability benefits of efficient infrastructure software

By requiring less CPU overhead, these solutions can significantly increase processor efficiency, which enables more virtual machines (VMs) per server, thereby reducing the number of physical servers required. It also extends the operational life of servers. These benefits contribute to environmental sustainability and cost efficiency. An efficient infrastructure software solution can also eliminate vendor lock-in, ensure long-term hardware flexibility, replace dedicated all-flash storage arrays with server-class SSDs, and incorporate backup best practices into the core infrastructure software. Additionally, solutions can reduce power, cooling, data center footprint, and server acquisition costs.

Enhancing Server Performance and Reducing Physical Server Count

Integrating storage, virtualization, and network services into a unified software package can improve server performance. Such software can handle more workloads with fewer physical servers by optimizing resource allocation and management. This reduction in physical infrastructure leads to several sustainability benefits:

  1. Lower Energy Consumption: Fewer servers mean reduced energy requirements for operation and cooling, directly lowering the data center’s carbon footprint.
  2. Reduced E-Waste: Minimizing the number of physical servers significantly decreases the amount of electronic waste generated from obsolete hardware.
  3. Cost Savings: Lower energy consumption and reduced hardware needs translate to substantial cost savings in capital and operational expenditures.

Elimination of Vendor Lock-In with Efficient Infrastructure Software

Vendor lock-in has long been a challenge in enterprise IT environments, and it impacts the sustainability benefits of efficient infrastructure software. Traditional infrastructure solutions bind organizations to specific hardware vendors, limiting flexibility and driving up costs. An efficient infrastructure software solution mitigates this issue by providing hardware-agnostic capabilities:

  1. Freedom of Choice: Organizations can choose hardware based on performance, cost, and sustainability criteria rather than being constrained by vendor compatibility.
  2. Competitive Pricing: The ability to mix and match hardware from different vendors fosters a competitive market, driving down prices and encouraging innovation.
  3. Sustainability Through Longevity: Hardware-agnostic software can support older servers, extending their useful life and reducing the need for frequent hardware replacements.

Efficient Infrastructure Software Delivers Long-Term Hardware Flexibility

One of the significant sustainability benefits of an efficient infrastructure software solution is its support for long-term hardware flexibility. This capability allows organizations to extend the operational life of their servers well beyond the original warranties:

  1. Extended Lifespan: With the correct software optimizations, servers can remain functional and efficient for many years, delaying the need for new hardware.
  2. Reduced Resource Consumption: By prolonging the life of existing hardware, the demand for raw materials and energy associated with manufacturing new servers is minimized.
  3. Economic Efficiency: Extending hardware lifespan translates to reduced capital expenditure on new equipment and better return on investment for existing assets.

However, as servers age, the risk of hardware failure increases. To mitigate this risk, built-in server redundancy and seamless failover capabilities are essential. Efficient infrastructure software should include these features to ensure continuous operation if an older server fails. This built-in redundancy allows workloads to be automatically transferred to functioning servers without disruption, maintaining high availability and reliability. Such resilience ensures that the extended use of older hardware does not compromise the overall stability and performance of the IT environment.

Eliminating Dedicated All-Flash Storage Arrays

Traditional data centers rely on dedicated all-flash storage arrays to meet high-performance processing and storage demands. However, this approach can be resource-intensive and costly. By integrating storage services directly into the server infrastructure and utilizing server-class SSDs, organizations can achieve comparable, if not superior, performance with greater efficiency:

  1. Cost Efficiency: Server-class SSDs are typically more cost-effective than dedicated all-flash storage arrays, reducing initial investment and ongoing maintenance costs.
  2. Improved Resource Utilization: Integrating storage into server infrastructure optimizes the use of existing resources, enhancing overall efficiency.
  3. Environmental Impact: The production of server-class SSDs generally requires fewer resources than all-flash storage arrays, contributing to a smaller environmental footprint.
  4. Elimination of Separate Network Infrastructure: Efficient infrastructure software eliminates the need for a separate network infrastructure dedicated solely to storage traffic, such as Fibre Channel or iSCSI. By consolidating storage traffic over existing Ethernet networks, organizations can reduce complexity, lower costs, and decrease the physical footprint of networking hardware. This simplification also reduces power and cooling requirements, further enhancing the sustainability of the IT environment.

Integrating Backup Best Practices Into Efficient Infrastructure Software

Incorporating backup and data protection best practices directly into the core infrastructure software eliminates the need for separate data protection architectures. This integration offers several sustainability and efficiency benefits:

  1. Simplified Management: A unified approach to data protection streamlines management processes, reducing the need for additional hardware and administrative overhead.
  2. Enhanced Resiliency: Integrated backup solutions ensure that data is consistently protected and readily recoverable, minimizing downtime and data loss.
  3. Resource Optimization: By leveraging existing infrastructure for backup purposes, organizations can avoid the additional energy and material costs associated with dedicated backup systems.
  4. Elimination of Separate Storage Systems and Servers: The integration of the data protection architecture eliminates the need for separate storage systems to store backup data and separate servers to run the backup software. This consolidation reduces the overall hardware footprint, significantly saving space, power, and cooling costs.

The Requirements of Efficient Infrastructure Software

the sustainability benefits of efficient infrastructure software

Efficient infrastructure software must meet several essential requirements to support modern data centers effectively while promoting sustainability and cost-efficiency. These requirements include integrating essential components, multi-tenancy capabilities, data resiliency, high availability, and scalability.

  • Integration of Major Components: The software must integrate the three major components of the data center—storage services, virtualization software, and networking services—into a single piece of software.
  • Integrated Multi-Tenancy: The software should provide integrated multi-tenancy to eliminate the noisy neighbor problem and ensure fair resource distribution among different workloads.
  • Data Resiliency and High Availability It should integrate data resiliency and high-availability features for servers to protect against hardware failures and ensure continuous operation.
  • Scalability: The software must scale from as few as two servers to hundreds of servers, allowing it to meet a wide range of use cases from Remote Office/Branch Office (ROBO) setups all the way up to large Enterprise environments.

Conclusion

Verge.io’s VergeOS meets all the requirements for efficient infrastructure software and delivers on the sustainability benefits discussed. VergeOS integrates storage services, server virtualization, and networking services into a single, cohesive platform, ensuring seamless operation and high performance. Its built-in multi-tenancy eliminates the noisy neighbor problem, and its data resiliency and high-availability features protect against hardware failures.

In addition to these technical advantages, VergeOS offers significant cost savings. Its licensing model is per server instead of per core, enabling customers to purchase fewer, more CPU-dense servers. This approach reduces licensing costs and lowers the overall number of servers required, enhancing sustainability by reducing energy consumption and electronic waste. VergeOS is also software-based, which means you can use your existing hardware or purchase new servers from the vendor of your choice.

Organizations adopting VergeOS can achieve all the sustainability benefits while enjoying upfront savings compared to VMware. VergeOS’s ability to scale from two servers to 200 makes it versatile for various use cases, from small remote offices to large enterprise environments. By choosing VergeOS, organizations can meet their environmental goals and achieve long-term operational success.

BOSTON – June 18, 2024 – IT service provider Cloud Compliance Solutions, Inc. (CCSI) has upgraded its infrastructure with technology from Leostream Corporation, creator of the world-leading Leostream® Remote Desktop Access Platform, and VergeIO, the leading VMware alternative, resulting in significant cost savings, optimized hardware use, and enhanced operational efficiency, the companies announced today.

Founded in 2017, CCSI provides its clients with a complete suite of cloud-related IT and compliance services. As a single provider offering both critical services, CCSI delivers more accurate and cost-effective IT and compliance solutions that significantly reduce its clients’ operational and audit costs.

CCSI opted to replace VMware due to significant challenges, including affordability, scaling and performance for its multi-tenant platform that provides its clients Desktop as a Service (DaaS)/Next-Gen DaaS (NGDaaS), Infrastructure as a Service (IaaS) and Disaster Recovery as a Service (DRaaS). CCSI’s growth had surpassed VMware’s capabilities, and it needed an option that could support denser environments with more powerful servers. Strategically, CCSI had concerns about VMware’s new licensing costs and models that required substantial upfront commitments and the uncertain future of VMware Horizon.

The transition to VergeIO and Leostream has transformed CCSI’s service portfolio, enabling it to offer more robust and scalable services with superior DaaS/NGDaaS, IaaS and DRaaS. With CCSI competing with providers like AWS and Azure, the upgrade allows it to remain price-competitive and provide better service and support.

“VergeOSs multi-tenant virtual data center technology and Leostream’s virtual desktop platform have empowered CCSI to provide customers with fundamentally better performance and efficiency,” said Kelley Allen, CCSI CEO. “This project exemplifies CCSI’s commitment to innovation and customer satisfaction with high-quality, affordable, and reliable IT solutions.”

The phased upgrade began with DaaS/NGDaaS and Leostream for remote desktop services including resource allocation, access control, and policy enforcement. In addition to secure user profile management and support for nearly all end-user devices and display protocols,the combined solution delivered on its promise of increased performance: boot times have dropped to seconds instead of minutes.

Next, CCSI shifted its IaaS offerings to VergeIO to create multi-tenant virtual data centers (VDC), which allows customers to manage the VDC as if it were on-premises technology, with CCSI as backup IT support. While CCSI is a de-facto IT team for many customers with limited or no full-time IT staff, VergeIO’s VDC technology allows CCSI to attract new clients whose IT teams want more control over their infrastructure.

The third phase, also enabled by VergeIO, expanded and simplified CCSI’s DRaaS capability so customers with on-premises IT infrastructure can fail over to CCSI’s infrastructure in a disaster. VergeOS VDC technology seamlessly replicates all components to ensure a successful recovery in CCSI’s data center.

“When industry-leading IT experts like CCSI choose your product for their own internal use, and to deploy to customers, it is the highest possible endorsement,” said Karen Gondoly, Leostream CEO. “This joint infrastructure combining Leostream and VergeIO has been battle-tested in multiple enterprises and we believe it’s the strongest, most feature-rich alternative to VMware, ESXi, and Horizon available today.”

“CCSI’s new architecture will provide long-term cost savings, starting with reduced upfront license costs, maintaining its existing investment in hardware, and enabling more virtual machines and desktops per physical server,” said Yan Ness, CEO of VergeIO. “More importantly, this modernized desktop, infrastructure, and disaster recovery platform has expanded what the company is able to offer its own clients, to truly do more for less.”

IT professionals often reject hyperconverged infrastructure (HCI) because they want to integrate HCI into their traditional three-tier architecture, and most HCI solutions can’t meet this requirement. HCI vendors also only focus on three tiers of the typical data center: networking, virtualization, and storage. However, a fourth tier is far too often overlooked: data availability and protection.

VergeOS’ Ultraconverged Infrastructure (UCI) can integrate into a customer’s traditional three-tier architecture. In this article, we will cover how VergeOS enables a more gradual onramp to UCI instead of a complete overhaul on day one and allows you to use components from each of your existing tiers.

UCI, an HCI Solution You Actually Want

Integrate HCI into a Three-Tier Architecture

The concept of HCI has merit. Take the data center tiers running on dedicated, vendor-provided hardware and reenable them as software, converging that software onto a single commodity server, liberating the organization from vendor lock-in and markups. The problem faced when IT attempts to integrate HCI into a traditional three-tier architecture is that HCI doesn’t truly converge anything. HCI stacks these tiers as software packages on top of each other, essentially recreating the same technology stack within a single server. It also forces them to exclude external SANs and existing servers.

UCI changes this by collapsing these stacks into a single, cohesive operating environment that is significantly more efficient. This elegant code base reduces overhead by as much as 30% while improving performance. The result is a VMware Alternative that is more portable, performs better, and provides improved data resilience.

UCI, an HCI Solution That Supports Fibre Channel SANs

One of the largest investments in the data center is the storage tier. If you have hundreds of thousands of dollars invested in a fibre-channel (FC) storage area network (SAN), you will want to integrate HCI into your traditional three-tier architecture so that you can continue to benefit from your significant investment. The problem is that most HCI solutions don’t support them. Because VergeIO owns all the code within VergeOS at a very deep level, we have taken the necessary steps to support fibre-channel-attached storage.

Click to Register

When using VergeIO and a FC SAN, you’ll need a physically local drive in each server to load VergeOS and store metadata, but the VM data can reside on the FC array. You’ll create a LUN as a virtual drive for each node that contributes to storage for the VergeOS instance. The VergeOS will manage and aggregate virtual drives into a pool that the VMs can use for data storage. VergeOS will also provide an additional layer of protection from hardware failure and add a deduplication capability. If your array already has deduplication, you can turn it off or leave it on; we’ve been unable to measure any noticeable performance impact.

In the future, when it is time to add additional capacity to the environment, you have options. First, you can continue to add capacity to your existing FC array, or you can take advantage of the 10X cost savings of using internal server class NVMe SSDs and/or HDDs. Also, as new storage technologies come to market, there is a much higher likelihood of them being supported sooner under VergeOS than waiting for the storage vendor to retrofit their designs to support them.

UCI, an HCI Solution That Supports Blade Servers

VergeOS is unique in that it can run a variety of different servers within the same instance. You can mix different server manufacturers, processor generations, and even processor manufacturers (Intel and AMD). You can also mix different server configurations. Some servers can be storage-heavy, and others can be processor-heavy.

Integrate HCI into a Three-Tier Architecture

Blade servers are processor-heavy nodes because they can only support a limited amount of internal storage. This makes blade servers problematic for IT professionals looking to integrate HCI into a traditional three-tier architecture. It forces them to reconsider the server strategy, which blade server customers are reluctant to do.

To incorporate a blade server into the VergeIO instance, you need to have either one internal drive store to boot VergeOS, or VergeOS also supports PXE booting, so an internal drive is not required. From there, the blade server can access its data from the shared pool of storage that VergeOS creates from the other nodes, or in the aforementioned FC SAN. In fact, if the blade server is FC equipped, it can “contribute” storage to the overall instance by assigning it a LUN as described above. Hosting storage does require slightly more RAM, so it is best to review the exact configuration with our technical architects.

As is the case with storage, VergeOS brings added flexibility for server expansion or refreshes. When it comes time to upgrade or expand your server infrastructure, you can continue to add blade servers or use standard 1U, 2U, or larger commodity servers of your choice.

UCI, an HCI Solution That Supports External Networks

Integrate HCI into a Three-Tier Architecture

VergeOS has a robust set of layer 2 and layer 3 networking functionality, but its use is optional. If you’ve invested in one of the market leaders for networking functionality, VergeOS can easily interoperate with them. As with the above, as time goes on, you can decide to use some of the network functionality built into VergeOS, saving you the cost of additional dedicated appliances, or you can continue to use your current vendor. To learn more about VergeOS, watch our Networking Fundamentals video.

UCI, an HCI Solution That Supports Third-Party Backup

VergeOS’ Data Availability Services combined with ioGuardian capabilities lessen IT’s dependency on the backup infrastructure for most recovery efforts, and many customers decide that is all the protection they need. VergeOS provides an in-guest agent that can quiesce when applying consistent snapshots. Still, some customers want to use third-party backup solutions to meet these requirements:

Copy of Last Resort

VergeOS can export the VMs’ raw files via an NFS mount point that almost any backup product can browse to meet compliance or vendor-independent data copy requirements to a different storage system, even tape.

File Level Restoration

As we show in this video, several types of file-level restoration can be done by leveraging VergeOS snapshots. Customers who want a centralized file-level recovery can install an in-guest agent from their backup software application into the virtual machines that are likely to require single-file recoveries.

Again, most customers find they can meet 100% of their data protection and recovery needs using VergeIO. Still, its support of third-party backup products enables IT to continue to use these solutions if required, or until they gain full confidence in VergOS’ capabilities.

Many IT Professionals disqualify Hyperconverged Infrastructure (HCI) as a VMware Alternative because they feel that overcoming HCI shortcomings is more expensive than continuing to use legacy three-tier architectures. These shortcomings are in areas where HCI was initially intended to excel: price, performance, scalability, and simplicity.

Overcoming HCI shortcomings led the VergeIO team to start from a clean slate and create the industry’s first UltraConverged Infrastructure (UCI) solution, VergeOS. It provides a superior, cost-effective alternative to HCI and the traditional three-tier infrastructure. Watch our on-demand webinar, “Beyond HCI” for a comparison of VergeOS’ UCI to the VMware and Nutanix HCI solutions.

In this article, we will explore the critical shortcomings of HCI, which lead IT planners to continue to leverage dedicated infrastructure, and how UCI overcomes them.

Can HCI Deliver Better CPU Performance?

The short answer is no. HCI can’t outperform the traditional three-tier architecture, which has dedicated hardware powering each tier. The reason is that HCI uses shared hardware to power at least four separate software packages, to deliver:


1) A package that contains the core operating system and the hypervisor.
2) A package that contains the storage software.
3) A package that contains the network software.
4) A package that contains the management software.

Each of these packages consumes CPU resources, and HCI’s lack of integration between them means it discards the potential gains in efficiency that combining them into a single code base would deliver. IT must install these packages as separate entities, making installation more complex. Then, once they are all installed and running and IT is ready to create a VM for the organization instead of for infrastructure, they’ve already lost as much as 20% of the CPU resources. To compensate, HCI requires the purchase of more powerful (and expensive) servers.

Another challenge is that as your application executes within the VM, it is probably running through much of the above stack. It uses the CPU to process requests from users. It is using storage IO to read and write data. It is using network resources to receive that input and deliver results. Finally, the VM’s health is reported to a management console in order to report on its health. Each transaction that the application executes is mired down in overhead.

The inefficiency of the code base forces HCI vendors into a predictable pattern of making customers buy turnkey hardware and software solutions from them, or buy new hardware using a strict hardware compatibility matrix. The required hardware must also be overpowered to compensate for the inefficiency, increasing costs.

UCI Delivers Near Bare Metal Performance

Can HCI Deliver Better CPU Performance

The fundamental difference between UCI and HCI is that UCI goes the extra step and eliminates the four separate software modules listed above. Instead, it integrates them into a cohesive code base, increasing resource efficiency. VergeIO typically uses less than 3-5% of CPU resources. The efficiency of resources also improves each VM transaction since no layers of code are involved in each request.

VergeIO customers consistently report measurable improvement in performance-demanding VMs and increased VM density while using existing hardware. Many VergeIO customers even report virtualizing formerly bare metal workloads and seeing a performance improvement.

Can HCI Deliver Better Storage Performance?

Concerns over storage performance are the number one reason customers will disqualify HCI in favor of dedicated three-tier architectures. Storage performance and storage scalability are very legitimate concerns for HCI vendors. First, most HCI vendors don’t use their own storage software. Often, they use an open-source solution like ZFS or CEPH, which were not designed for the unique requirements of providing storage services to a virtualized infrastructure. The solution remains convoluted even if they have their storage code.

Because of the lack of integration, HCI vendors have stumbled through implementing advanced drive failure protection and storage efficiency algorithms like deduplication. Adding these capabilities post-facto adds another layer to an already complex combination of software. For this reason, most vendors force customers to choose between storage efficiency and advanced drive redundancy.

The storage performance delivered by a UCI solution like VergeOS can outperform an HCI solution and a dedicated storage array while significantly reducing the storage cost. VergeOS correctly balances storage efficiency and storage performance. Its deep integration into the core software enables features like drive failure protection and global inline deduplication to work without adversely impacting performance.

Can HCI Deliver Better Scale?

By its very nature, HCI is scale-out, so scale should be an advantage, but once again, it falls short. Most HCI solutions require three servers (nodes) to start. It forces many small data centers to use two servers and a SAN or NAS. Many of these customers would benefit from a simple two-node solution that includes all the storage and networking functionality within those nodes.

HCI also doesn’t meet the scaling demands of enterprises. Most HCI solutions can only scale to eight nodes per instance before network traffic becomes challenging. They also have to buy similar nodes with each upgrade. If their needs change, they have to start an entirely separate instance of the HCI environment. As a result, many customers opt for the legacy three-tier architecture because each tier can be scaled independently of the other.

UCI Delivers Better Scale

Overcoming HCI shortcomings requires an infrastructure that is flexible and can adapt to the changing demands of the organization.

As we explain in our article “The Full Value of Scale”, a UCI solution like VergeOS delivers a three-dimensional scale. It can start with as few as two nodes, making it ideal for small data centers and remote offices, but it can also scale to hundreds of nodes to meet the needs of the most demanding enterprise. Nodes within the VergeOS instance can be different from each other. Customers can use nodes that provide balanced compute and storage, or mainly compute, or mostly storage, have GPUs installed, or any combination of the above.

Why is HCI More Expensive than Legacy Three Tier?

HCI should have a significant price advantage over legacy three-tier infrastructure. By definition, it is supposed to use off-the-shelf commodity servers, storage, and network hardware. However, this is seldom the case. Under the guise of “making it easy to install and support,” these vendors either require you to buy a turnkey hardware and software solution from them, require you to buy a specific configuration from one of their “certified” hardware vendors, or have a rigorous hardware compatibility list.

The inefficiency of layering virtualization software, storage software, and networking software as three separate software packages also drives up the cost of HCI. Customers must buy much more powerful nodes to support the additional overhead.

UCI Delivers Better TCO and ROI

Overcoming HCI shortcomings requires an infrastructure that can deliver the promise of reduced cost and simplified operations.

VergeOS’ tight integration of the hypervisor, storage, and networking software means customers can actually use off-the-shelf storage from whichever vendor they choose. This flexibility means there is no need to pay a premium for a so-called turnkey solution. Additionally, because VergeOS is licensed by the physical server, not the contents of that server, as you scale your environment, you can use quad-socket servers with massive core counts and not get crushed in licensing costs.

As we discuss in our article “The High Cost of Dedicated Storage”, VergeOS also dramatically lowers the cost of storage. You can use off-the-shelf server-class flash and hard disk drives, eliminating the 5X to 10X markup levied by dedicated storage array vendors.

The savings even follow through to the network. With VergeOS, you can use off-the-shelf commodity switches. When ready, you can replace dedicated network appliances like firewalls with VergeOS’ built-in L2 and L3 networking capabilities.

Conclusion

In conclusion, Hyperconverged Infrastructure (HCI) makes a poor foundation for an alternative to VMware, particularly in CPU performance, storage efficiency, scalability, and cost. Despite HCI’s initial promises of simplifying operations and reducing costs, it typically fails to meet these objectives due to its inherent inefficiencies.

Yet the cost and complexities of three-tier architectures remain. This has led to the development of VergeIO’s UltraConverged Infrastructure (UCI), which addresses HCI’s shortcomings as well as the three-tier challenges. VergeOS integrates infrastructure software modules into a single, cohesive codebase, enhancing performance and scalability while reducing costs. As such, it presents itself as a more viable solution for customers seeking a VMware alternative as well as for those seeking a simpler, more scalable data center infrastructure.
