Dell XC Web-Scale Hyperconverged Series: A Solution for your Most Dynamic Virtualized Environments

Over the past few years, to reduce cost and to improve time-to-value, converged infrastructure systems – the integration of compute, networking and storage - have been readily adopted by large enterprise users. The success of these systems results from the deployment of purpose built integrated converged infrastructure optimized for the most common IT workloads like Private Cloud, Big Data, Virtualization, Database and Desktop Virtualization (VDI). Traditionally these converged infrastructure systems have been built using a three-tier architecture; where compute, networking and storage, while integrated together in same rack, still consisted of best-in-breed standalone devices. These systems work well in stable, predictable environments, however, when a virtualization environment is dynamic with unpredictable growth, traditional three-tier architectures often times lack the simplicity, scalability and flexibility needed to operate in such environment.

Enter HyperConvergence, where the three-tier architecture has been collapsed into a single system that is purpose-built for virtualization from the ground up with virtualization, compute and storage, along with advanced features such as deduplication, compression and data protection, are all integrated into an x86 industry-standard building block node. These devices are built upon scale-out architectures with a 100% VM centric management paradigm. The simplicity, scalability and flexibility of this architecture make it a perfect fit for dynamic virtualized environments.

Dell XC Web-scale Converged Appliances powered by Nutanix software are delivered as a series of HyperConverged models that are extremely flexible and scalable. In this solution brief we will examine what constitutes a dynamic virtualized environment and how the Dell XC Web-scale Appliance series fits into such an environment. We can confidently state that by implementing Dell’s XC flexible range of Web-scale appliances, businesses can deploy solutions across a broad spectrum of virtualized workloads where flexibility, scalability and simplicity are critical requirements. Dell is an ideal partner to deliver Nutanix software because of its global reach, streamlined operations and enterprise systems solutions expertise. The company is well positioned to bring HyperConverged platforms to the masses and introduce the technology to a new set of customers previously unreached.

Unified Storage Array Efficiency: HP 3PAR StoreServ 7400c versus EMC VNX 5600 (TVS)

The IT industry is in the middle of a massive transition toward simplification and efficiency around managing on-premise infrastructure at today’s enterprise data centers. In the past few years there has been a rampant onset of technology clearly focused at simplifying and radically changing the economics of traditional enterprise infrastructure. These technologies include Public/Private Clouds, Converged Infrastructure, and Integrated Systems to name a few. All of these technologies are geared to provide more efficiency of resources, take less time to administer, all at a reduced TCO. However, these technologies all rely on efficiency and simplicity of the underlying technologies of Compute, Network, and Storage. Often times the overall solution is only as good as the weakest link in the chain. The storage tier of the traditional infrastructure stack is often considered the most complex to manage.

This technology validation focuses on measuring the efficiency and management simplicity by comparing two industry leading mid-range external storage arrays configured in the use case of unified storage. Unified storage has been a popular approach to storage subsystems that consolidates both file access and block access within a single external array thus being able to share the same precious drive capacity resources across both protocols simultaneously. Businesses value the ability to send server workloads down a high performance low latency block protocol while still taking advantage of simplicity and ease of sharing file protocols to various clients. In the past businesses would have either setup a separate file server in front of their block array or buy completely separate NAS devices, thus possibly over buying storage resource and adding complexity. Unified storage takes care of this by providing ease of managing one storage device for all business workload needs. In this study we compared the attributes of storage efficiency and ease of managing and monitoring an EMC VNX unified array versus an HP 3PAR StoreServ unified array. The approach we used was to setup two arrays side-by-side and recorded the actual complexity of managing each array for file and block access, per the documents and guides provided for each product. We also went through the exercise of sizing various arrays via publicly available configuration guides to see what the expected storage density efficiency would be for some typically configured systems.

Our conclusion was nothing short of astonishment. In the case of the EMC VNX2 technology, the approach to unification more closely resembles a hardware packaging and management veneer approach than what would have been expected for a second generation unified storage system. HP 3PAR StoreServ on the other hand, in its second generation of unified storage has transitioned the file protocol services from external controllers to completely converged block and file services within the common array controllers. In addition, all the data path and control plumbing is completely internal as well with no need to wire loop back cables between controllers. HP has also made the investment to create a totally new management paradigm based on the HP OneView management architecture, which radically simplifies the administrative approach to managing infrastructure. After performing this technology validation we can state with confidence that HP 3PAR StoreServ 7400c is 2X easier to provision, 2X easier to monitor, and up to 2X more data density efficient than a similarly configured EMC VNX 5600.

OneCloud Software: DR For the Masses

With the advent of server virtualization, many adopters erroneously think that disaster recovery (DR) is a problem of the past. They cite the ability of the hypervisors to replace the two most common yet imperfect DR choices: 1) infrastructure replication to a secondary replica site – fast to restore but very expensive, or 2) economical tape backup with off-site long-term storage – economical but slow to recover from.

The reality is that while server virtualization has certainly helped the industry get closer to simpler and less expensive DR products, DR still remains one of the major challenges for IT. This is especially true for applications that fall somewhere between the most mission critical where RTOs and RPOs of a few seconds is needed (and cost is often no object) and those that find RTOs and RPOs of a day or two to be adequate. Today, DR products available for these “intermediate” applications are few and far between, especially when overall cost of DR is considered.  

The missing piece so far has been a cost-effective DR solution with excellent RTO and RPO for the majority of business applications -- without requiring a secondary site. OneCloud steps into the gap by replacing that expensive site with the hyper-scale public cloud. This Profile will discuss how OneCloud works to extend the primary data center onto the cloud, and how this impacts the ease and speed of VM recovery.

What Admins Choose For Performance Management: Galileo’s Cross-Domain Insight Served via Cloud

Every large IT shop has a long shelf of performance management solutions ranging from big platform bundles bought from legacy vendors, through general purpose log aggregators and event consoles, to a host of device-specific element managers. Despite the invested costs of acquiring, installing, supporting, and learning these often complex tools, only a few of them are in active daily use. Most are used only reactively and many just gather dust for a number of reasons. But, if only because of the ongoing costs of keeping management tools current, it’s only the solutions that get used that are worth having.

When it comes to picking which tool to use day-to-day, it’s not the theory of what it could do, it’s the actual value of what it does for the busy admin trying to focus on the tasks at-hand. And among the myriad of things an admin is responsible for, assuring performance requires the most management solution support. Performance related tasks include checking on the health of resources that the admin is responsible for, improving utilization, finding lurking or trending issues to attend to in order to head off disastrous problems later, working with other IT folks to diagnose and isolate service impacting issues, planning new activities, and communicating relevant insight to others – in IT, the broader business, and even to external stakeholders.

Admins responsible for infrastructure, when faced with these tasks, have huge challenges in large, heterogeneous, complex environments. While vendor-specific device and element managers drill into each piece of equipment, they help mostly with easily identifiable component failure. Both daily operational status and difficult infrastructure challenges involve looking across so-called IT domains (i.e. servers and storage) for thorny performance impacting trends or problems. The issue with larger platform tools is that they require a significant amount of installation, training, ongoing tool support, and data management that all detract from the time an admin can actually spend on primary responsibilities.

There is room for a new style of system management that is agile, insightful and empowering, and we think Galileo presents just such a compelling new approach. In this report we’ll explore some of the IT admin’s common performance challenges and then examine how Galileo Performance Explorer with its cloud-hosted collection and analysis helps conquer them. We’ll look at how Performance Explorer crosses IT domains to increase insight, easily implements and scales, fosters communication, and focuses on and enables the infrastructure admin to achieve daily operational excellence. We’ll also present a couple of real customer interviews in which, despite sunk costs in other solutions, adding Galileo to the data center quickly improved IT utilization, capacity planning, and the service levels delivered back to the business.
