Even with the improved ease-of-use with converged 3-tier products like EMC VCE, customers routinely see complexity and cost as key reasons to switch to HCI.
HyperConverged Infrastructure Powered by Pivot3: Benefits of a More Efficient HCI Architecture
Virtualization has matured and become widely adopted in the enterprise market. HyperConverged Infrastructure (HCI), with virtualization at its core, is taking the market by storm, enabling virtualization for businesses of all sizes. The success of these technologies has been driven by an insatiable desire to make IT simpler, faster, and more efficient. IT can no longer afford the time and effort required to create custom infrastructure from best-of-breed DIY components.
With HCI, the traditional three-tier architecture has been collapsed into a single system that is purpose-built for virtualization. In these solutions, the hypervisor, compute, storage, and advanced data services are integrated into an x86 industry-standard building block. The immense success of this approach has led to increased competition in this space and the customers are required to sort through the various offerings, analyzing key attributes to determine which are significant.
One of these competing vendors, Pivot3, was founded in 2002 and has been in the HCI market since 2008, well before the term HyperConverged was used. For many years, Pivot3’s vSTAC architecture has provided the most efficient scale-out Software-Defined Storage (SDS) system available on the market. This efficiency is attributed to three design innovations. The first is their extremely efficient and reliable erasure coding technology called Scalar Erasure Coding. Conversely, many leading HCI implementations use replication-based redundancy techniques which are heavy on storage capacity utilization. Scalar Erasure Coding from Pivot3 can deliver significant capacity savings depending on the level of drive protection selected. The second innovation is Pivot3’s Global Hyperconvergence which creates a cross-cluster virtual SAN, the HyperSAN: in case of appliance failure, a VM migrates to another node and continues operations without the need to divert compute power to copy data over to that node. The third innovation has been a reduction in CPU overhead needed to implement the SDS features and other VM centric management tasks. Implementation of the HCI software uses the same CPU complex as business applications, this additional usage is referred to as the HCI overhead tax. HCI overhead tax is important since the licensing cost for many applications and infrastructure software are based on a per CPU basis. Even with today’s ever- increasing cores per CPU there still can be significant cost saving by keeping the HCI overhead tax low.
The Pivot3 family of HCI products delivering high data efficiency with a very low overhead are an ideal solution for storage-centric business workload environments where storage costs and reliability are critical success factors. One example of this is a VDI implementation where cost per seat determines success. Other examples would be capacity-centric workloads such as big data or video surveillance that could benefit from a Pivot3 HCI approach with leading storage capacity and reliability. In this paper we compare Pivot3 with other leading HCI architectures. We utilized data extracted from the alternative HCI vendor’s reference architectures for VDI implementations. Using real world examples, we have demonstrated that with other solutions, users must purchase up to 136% more raw storage capacity and up to 59% more total CPU cores than are required when using equivalent Pivot3 products. These impressive results can lead to significant costs savings.
Pivot3, a pioneer and innovator in the development of hyper-converged infrastructure (HCI), today announced the release of the vSTAC OS Management Client Integration Plug-In, designed to connect with VMware vCenter Server.

Nutanix XCP For Demanding Enterprise Workloads: Making Infrastructure Invisible for Tier-1 Ent. Apps
Virtualization has matured and become widely adopted in the enterprise market. Approximately three in every five physical servers are deployed in a virtualized environment. After two waves of virtualization, it is safe to assume that a high percentage of business applications are running in virtualized environments. The applications last to deploy into the virtualized environment were considered the tier-1 apps. Examples of these include CRM and ERP environments running SAP NetWeaver, Oracle database and applications, and Microsoft SQL Server. In many 24X7 service industries, Microsoft Exchange and SharePoint are also considered tier-1 applications.
The initial approach to building virtualized environments that can handle these tier-1 applications was to build highly tuned infrastructure using best of breed three-tier architectures where compute, storage and networking were selected and customized for each type of workload. Newer shared storage systems have increasingly adopted virtualized all flash and hybrid architectures, which has allowed organizations to mix a few tier-1 workloads within the same traditional infrastructure and still meet stringent SLA requirements.
Enter now the new product category of enterprise-capable HyperConverged Infrastructure (HCI). With HCI, the traditional three-tier architecture has been collapsed into a single software-based system that is purpose-built for virtualization. In these solutions, the hypervisor, compute, storage, and advanced data services are integrated into an x86 industry-standard building block. These modern scale-out hyperconverged systems combine a flash-first software-defined storage architecture with VM-centric ease-of-use that far exceeds any three-tier approach on the market today. These attributes have made HCI very popular and one of the fastest growing product segments in the market today.
HCI products have been very popular with medium sized companies and specific workloads such as VDI or test and development. After a few years of hardening and maturity, are these products ready to tackle enterprise tier-1 applications? In this paper we will take a closer look at Nutanix Xtreme Computing Platform (XCP) and explore how its capabilities stack up to tier-1 application workload requirements.
Nutanix was a pioneer in HCI and is widely considered the market and visionary leader of this rapidly growing segment. Nutanix has recently announced the next step - a vision of the product beyond HCI. With this concept they plan to make the entire virtualized infrastructure invisible to IT consumers. This will encompass all three of the popular hypervisors: VMware, Hyper-V and their own Acropolis Hypervisor. Nutanix has enabled app mobility between different hypervisors, a unique concept across the converged system and HCI alike. This Solution Profile will focus on the Nutanix XCP platform and key capabilities that make it suitable for teir-1 enterprise applications. With the most recent release, we have found compelling features appropriate for most tier-1 application workloads. Combined with the value proposition of web-scale modular architecture this provides an easy pathway to data-center transformation that businesses of all sizes should take advantage of.
HyperConverged Infrastructure customers will become more discerning
While the term “software defined” loses some of its lustre, enterprises will continue to accelerate their investments in software defined storage and networking in 2016.

Scale Computing HC3: A Look at a Hyperconverged Appliance
Consolidation and enhanced management enabled by virtualization has revolutionized the practice of IT around the world over the past few years. By abstracting compute from the underlying hardware systems, and enabling oversubscription of physical systems by virtual workloads, IT has been able to pack more systems into the data center than before. Moreover, for the first time in seemingly decades, IT has also taken a serious leap ahead in management, as this same virtual infrastructure has wrapped the virtualized workload with better capabilities than ever before - tools like increased visibility, fast provisioning, enhanced cloning, and better data protection. The net result has been a serious increase in overall IT efficiency.
But not all is love and roses with the virtual infrastructure. In the face of serious benefits and consequent rampant adoption, virtualization continues to advance and bring about more capability. All too often, an increase in capability has come at the cost of complexity. Virtualization now promises to do everything from serving up compute instances, to providing network infrastructure and network security, to enabling private clouds.
For certain, much of this complexity exists between the individual physical infrastructures that IT must touch, and the simultaneous duplication that virtualization often brings into the picture. Virtual and physical networks must now be integrated, the relationship between virtual and physical servers must be tracked, and the administrator can barely answer with certainty whether key storage functions, like snapshots, should be managed on physical storage systems or in the virtual infrastructure.
Scale Computing, an early pioneer in HyperConverged solutions, has released multiple versions of HC3 appliances and now includes the 6th generation of Scale’s HyperCore Operating System. Scale Computing continues to push the boundary in regards to simplicity, value and availability that many SMB IT departments everywhere have come to rely on. HC3 is an integration of storage and virtualized compute within a scale-out building block architecture that couples all of the elements of a virtual data center together inside a hyperconverged appliance. The result is a system that is simple to use and does away with much of the complexity associated with virtualization in the data center. By virtualizing and intermingling compute and storage inside a system that is designed for scale-out, HC3 does away with the need to manage virtual networks, assemble complex compute clusters, provision and manage storage, and a bevy of other day to day administrative tasks. Provisioning additional resources - any resource - becomes one-click-easy, and adding more physical resources as the business grows is reduced to a simple 2-minute exercise.
While this sounds compelling on the surface, Taneja Group recently turned our Technology Validation service - our hands-on lab service - to the task of evaluating whether Scale Computing's HC3 could deliver on these promises in the real world. For this task, we put an HC3 cluster through the paces to see how well it deployed, how it held up under use, and what special features it delivered that might go beyond the features found in traditional integrations of discreet compute and storage systems.
While we did touch upon whether Scale's architecture could scale performance as well as capacity, we focused our testing upon how the seamless integration of storage and compute within HC3 tackles key complexity challenges in the traditional virtual infrastructure.
As it turns out, HC3 is a far different system than the traditional compute and storage systems that we've looked at before. HC3's combination of compute and storage takes place within a scale-out paradigm, where adding more resources is simply a matter of adding additional nodes to a cluster. This immediately brings on more storage and compute resources, and makes adapting and growing the IT infrastructure a no-brainer exercise. On top of this adaptability, virtual machines (VMs) can run on any of the nodes, without any complex external networking. This delivers seamless utilization of all datacenter resources, in a dense and power efficient footprint, while significantly enhancing storage performance.
Meanwhile, within an HC3 cluster, these capabilities are all delivered on top of a uniquely robust system architecture that can tolerate any failure - from a disk to an entire cluster node - and guarantee a level of availability seldom seen by mid-sized customers. Moreover, that uniquely robust, clustered, scale-out architecture can also intermix different generation of nodes in a way that will put an end to painful upgrades by reducing them to simply decommissioning old nodes as new ones are introduced.
HC3’s flexibility, ease of deployment, robustness and a management interface is the simplest and easiest to use that we have seen. This makes HC3 a disruptive game changer for SMB and SME businesses. HC3 stands to banish complex IT infrastructure deployment, permanently alter on-going operational costs, and take application availability to a new level. With those capabilities in focus, single bottom-line observations don’t do HC3 justice. In our assessment, HC3 may take as little as 1/10th the effort to setup and install as traditional infrastructure, 1/4th the effort to configure and deploy a virtual machine (VM) versus doing so using traditional infrastructure, and can banish the planning, performance troubleshooting, and reconfiguration exercises that can consume as much as 25-50% of an IT administrator’s time. HC3 is about delivering on all of these promises simultaneously, and with the additional features we'll discuss, transforming the way SMB/SME IT is done.
Business Continuity Best Practices for SMB
Virtualization’s biggest driver is big savings: slashing expenditures on servers, licenses, management, and energy. Another major benefit is the increased ease of disaster recovery and business continuity (DR/BC) in virtualized environments.
Note that disaster recovery and business continuity are closely aligned but not identical. We define disaster recovery as the process of restoring lost data, applications and systems following a profound data loss event, such as a natural disaster, a deliberate data breach or employee negligence. Business continuity takes DR a step further. BC’s goal is not only to recover the computing environment but also to recover them swiftly and with zero data loss. This is where recovery point objectives (RPO) and recovery time objectives (RTO) enter the picture, with IT assigning differing RPO and RTO strategies according to application priority.
DR/BC can be difficult to do well in data centers with traditional physical servers, particularly in SMB with limited IT budgets and generalist IT staff. Many of these servers are siloed with direct-attached storage and individual data protection processes. Mirroring and replication used to require one-to-one hardware correspondence and can be expensive, leading to a universal reliance on localized backup as data protection. In addition, small IT staffs do not always take the time to perfect their backup processes across disparate servers. Either they do not do it at all –rolling the dice and hoping there won’t be a disaster – or they slap backups on tape or USB drives and stick them on a shelf.
Virtualization can transform this environment into a much more efficient and protected data center. Backing up VMs from a handful of host servers is faster and less resource-intensive than backing up tens or hundreds of physical servers. And with scheduled replication, companies achieve faster backup and much improved recovery objectives.
However, many SMBs avoid virtualization. They cite factors such as cost, unfamiliarity with hypervisors, and added complexity. And they are not wrong: virtualization can introduce complexity, it can be expensive, and it can require familiarity with hypervisors. Virtualization cuts down on physical servers but is resource-intensive, especially as the virtualized environment grows. This means capital costs for high performance CPUs and storage. SMBs may also have to deal VM licensing and management costs, administrative burdens, and the challenge of protecting and replicating virtualized data on a strict budget.
For all its complexity and learning curve, is virtualization worth it for SMBs? Definitely. Its benefits far outweigh its problems, particularly its advantages for DR/BC. But for many SMBs, traditional virtualization is often too expensive and complex to warrant the effort. We believe that the answer is HyperConverged Infrastructure: HCI. Of HCI providers, Scale Computing is exceptionally attractive to the SMB. This paper will explain why.
With the hype around converged and hyper-converged IT infrastructure, resistance seems futile. While your IT organization will likely be a mix of converged, dedicated and cloud-based resources, convergence is moving into new areas.

The Hyperconverged Data Center: Nutanix Customers Explain Why They Replaced Their EMC SANS
Taneja Group spoke with several Nutanix customers in order to understand why they switched from EMC storage to the Nutanix platform. All of the respondent’s articulated key architectural benefits of hyperconvergence versus a traditional 3-tier solutions. In addition, specific Nutanix features for mission-critical production environments were often cited.
Hyperconverged systems have become a mainstream alternative to traditional 3-tier architecture consisting of separate compute, storage and networking products. Nutanix collapses this complex environment into software-based infrastructure optimized for virtual environments. Hypervisor, compute, storage, networking, and data services run on scalable nodes that seamlessly scale across massive virtual assets. Hyperconvergence offers a key value proposition over 3-tier architecture: instead of deploying, managing and integrating separate components – storage, servers, networking, data services, and hypervisors – these components are combined into a modular high performance system.
The customers we interviewed operate in very different industries. In common, they all maintained data centers undergoing fundamental changes, typically involving an opportunity to refresh some portion of their 3-tier infrastructure. This enabled the evaluation of hyperconvergence in supporting those changes. Customers interviewed found that Nutanix hyperconvergence delivered benefits in the areas of scalability, simplicity, value, performance, and support. If we could use one phrase to explain why Nutanix’ is winning over EMC customers in the enterprise market it would be “Ease of Everything.” Nutanix works, and works consistently with small and large clusters, in single and multiple datacenters, with specialist or generalist IT support, and across hypervisors.
The five generations of Nutanix products span many years of product innovation. Web-scale architecture has been the key to Nutanix platform’s enterprise capable performance, simplicity and scalability. Building technology like this requires years of innovation and focus and is not an add-on for existing products and architectures.
The modern data center is quickly changing. Extreme data growth and complexity are driving data center directors toward innovative technology that will grow with them. Given the benefits of Nutanix web-scale architecture – and the Ease of Everything – data center directors can confidently adopt Nutanix as their partner in data center transformation just as the following EMC customers did.
Cisco's HyperFlex hyper-converged strategy depends largely on startup Springpath's file system performing better than those from Nutanix, VMware and other competitors.

Hyper-converged infrastructure may or may not cut hardware costs, but some CIOs and other industry executives suggest an emphasis on sticker price misses the point.
The Modern Data-Center: Why Nutanix Customers are Replacing Their NetApp Storage
Several Nutanix customers shared with Taneja Group why they switched from traditional NetApp storage to the hyperconverged Nutanix platform. Each customer talked about the value of hyperconvergence versus a traditional server/networking/storage stack, and the specific benefits of Nutanix in mission-critical production environments.
Hyperconverged systems are a popular alternative to traditional computing architectures that are built with separate compute, storage, and networking components. Nutanix turns this complex environment into an efficient, software-based infrastructure where hypervisor, compute, storage, networking, and data services run on scalable nodes that seamlessly scale across massive virtual environments.
The customers we spoke with came from very different industries, but all of them faced major technology refreshes for legacy servers and NetApp storage. Each decided that hyperconvergence was the right answer, and each chose the Nutanix hyperconvergence platform for its major benefits including scalability, simplicity, value, performance, and support. The single key achievement running through all these benefits is “Ease of Everything”: ease of scaling, ease of management, ease of realizing value, ease of performance, and ease of upgrades and support. Nutanix simply works across small clusters and large, single and multiple datacenters, specialist or generalist IT, and different hypervisors.
The datacenter is not static. Huge data growth and increasing complexity are motivating IT directors from every industry to invest in scalable hyperconvergence. Given Nutanix benefits across the board, these directors can confidently adopt Nutanix to transform their data-centers, just as these NetApp customers did.
