Making the invisible visible - the next generation data center (Virtual Instruments)

It has never been more important to be able to peer into the infrastructure to see what is going on - in the age of virtualization, consolidation, cloud services like automated provisioning and deployment, user self service, and more, there are now more complex interactions in the infrastructure than ever before.  Yet visibility comes down to approaching the physical infrastructure the right way to begin with, and we've seldom learned our lessons as well as we should.  In this solution profile, we'll take a look at the importance of designing for access and visibility.

Building the Virtual Infrastructure with DataCore SANsymphony-V

There's a ball and chain hanging on your virtualization projects - and it's that pesky storage stuff. Storage that isn't flexible, can't adapt to changes, is wrapped with poor provisioning practices, and where sheer physicality and lack of abstraction seem to get in the way of every virtual server task. There's no secret in the fact we think storage virtualization can set the virtual infrastructure free, but let's take a look at one vendor's product, and how it tackles some of those issues in the Hyper-V infrastructure.

Client Virtualization the HP Way

What’s driving customers to bigger and bigger desktop virtualization initiatives? What are the challenges they face, and what can be done to resolve hurdles, and speed customers on their way to better client virtualization infrastructures that actually deliver the benefits that attract them to desktop virtualization in the first place?

No doubt, desktop virtualization, or “client virtualization” in HP parlance, roared off to a thunderous start, and the industry has already seen many big initiatives and offerings. Moving into 2012, client virtualization increasingly looks to have the wherewithal to go entirely mainstream, and move into a much broader set of customers than the initial high profile adoptees who had unusual business needs or were turning up unique hosted services. Yet client virtualization remains a complex undertaking. HP thinks they have a clear understanding of that complexity, and a consequent solution approach built to eradicate that complexity from the equation. In turn, they aim to make the promises of client virtualization more compelling than ever, and allow customers to be certain of realizing those promises. In this solution profile, Taneja Group will take a look at the promises driving client virtualization, the challenges that too often pull those promises apart, and then look at how HP is driving those challenges out of the equation with a newly announce product – VirtualSystem CV2.

Closing the Virtual IO Management Gap

Assuring Service Throughout the Data Center with Infrastructure Performance Management

There is a significant and potentially costly management gap in virtualized server environments that rely solely on hypervisor-centric solutions. As organizations virtualize more of their mission-critical applications, they are discovering that the virtual versions of these apps continue to depend on the rock-solid storage availability and top-notch IO performance they had when physically hosted. Assuring great service to virtualized clients still requires deep performance management capabilities along the whole IO infrastructure path down to and including shared storage resources.

Cohesive hypervisor management solutions like VMware’s vCenter Operations Management Suite provide a significant advantage to virtual administration by centralizing and simplifying many traditionally disparate management tasks. However, there is a significant management blind spot in the view of end-to-end IO infrastructure when looking at it from the native virtual server perspective. Enterprises relying more and more on virtualized IT delivery need to address this natural management gap with Infrastructure Performance Management (IPM). A lack of robust IPM will degrade or even prevent the deployment of critical applications into a virtual environment – at best losing out on the benefits of virtualization and the opportunities for cloud, at worst causing severe degradation and service outages for all applications sharing the same virtual infrastructure pools.

In this paper we review the virtual performance management landscape and the management strengths of the most well-known hypervisor management solution – VMware’s vCenter Operations Suite - to understand why both the market perception and resulting admin reliance on it is so high. We look at how that reliance overlooks a critical gap for IO and storage, and what the implications of that blind spot are for ensuring total performance. Finally, we examine how the unique IO-centric capabilities of Virtual Instruments’ VirtualWisdom close that gap by correlating complete IO path monitoring with both physical and virtual infrastructure, and how by using VirtualWisdom with vCenter Ops one can achieve a complete end-to-end picture that enables mission-critical applications to be successfully virtualized.

Making The Virtual Infrastructure Non-stop: And Making Availability Efficient with Symantec’s VCS

The past few years have seen virtualization rapidly move into the mainstream of the data center. Today, virtualization is often the defacto standard in the data center for deployment of any application or service. This includes important operational and business systems that are the lifeblood of the business.

For mission critical systems, customers necessarily demand a broader level of services than is common among the test and development environments where virtualization often gains its foothold in the data center. It goes almost without saying that topmost in customer’s minds are issues of availability.

Availability is a spectrum of technology that offers businesses many different levels of protection – from general recoverability to uninterruptable applications. At the most fundamental level, are mechanisms that protect the data and the server beneath applications. While in the past these mechanisms have often been hardware and secondary storage systems, VMware has steadily advanced the capabilities of their vSphere virtualization offering, and it includes a long list of features – vMotion, Storage vMotion, vSphere Replication, VMware vCenter Site Recovery Manager, vSphere High Availability, and vSphere Fault Tolerance. While clearly VMware is serious about the mission critical enterprise, each of these offerings have retained a VMware-specific orientation toward protecting the “compute instance”.

The challenge is that protecting a compute instance does not go far enough. It is the application that matters, and detecting VM failures may fall short of detecting and mitigating application failures.

With this in mind, Symantec has steadily advanced a range of solutions for enhancing availability protection in the virtual infrastructure. Today this includes ApplicationHA – developed in partnership with VMware – and their gold standard offering of Veritas Cluster Server (VCS) enhanced for the virtual infrastructure. We recently turned an eye toward how these solutions enhance virtual availability in a hands-on lab exercise, conducted remotely from Taneja Group Labs in Phoenix, AZ. Our conclusion: VCS is the only HA/DR solution that can monitor and recover applications on VMware that is fully compatible with typical vSphere management practices such as vMotion, Dynamic Resource Scheduler and Site Recovery Manager, and it can make a serious difference in the availability of important applications.

HP StoreVirtual Virtual Storage Appliance - The VSA for scalable VM density (TVS)

Virtual Storage Appliances (VSAs) have been around for a while – just over 5 years ago, the earliest vendors started to sample market interest in this technology.  In theory, the market was interested, but perhaps more so on paper than in actual adoption during those early days.  Regardless, that interest drove more vendors to release VSAs and today there are dozens of Virtual Storage Appliances on the market.  Many of these are focused on capabilities such as backup, but at least a handful can serve as primary storage beneath the virtual infrastructure.

The primary storage VSAs on the market came about as product or marketing experiments; perhaps to let customers experience a storage system without making a full investment, allow customers to ingest rogue virtual infrastructure storage back into their existing storage infrastructure, or enable consistent storage management as customers deployed workloads with remote service providers.

For certain, many of these primary storage VSAs have never found their footing, and still languish as a neglected technology in a dusty corner of a vendor’s product portfolio.  But there have been exceptions.  One is HP StoreVirtual.  HP has been quite serious about delivering StoreVirtual as a real storage solution with hefty capabilities.  StoreVirtual is one of HP’s several converged storage technologies that is blurring the boundaries between storage and compute, and helping customer infrastructures to scale and adapt while maintaining maximum efficiency.  The popular StoreVirtual product line comes in a variety of physical formats, from entry-level 1U 4 drive systems to extremely dense BladeSystem SANs.  Approximately 5 years ago, the StoreVirtual software foundation was also released in Virtual Storage Appliance form.  This StoreVirtual VSA is a full storage system that looks, acts, and functions just like its physical StoreVirtual brethren.  The intent behind HP’s StoreVirtual VSA is increased ease of use, increased storage functionality in the virtual infrastructure, and greater adaptability, within a dense footprint that can make use of any available storage resources (direct attached server storage or networked storage).  HP claims that StoreVirtual VSA leads the market in ease of use, performance, efficiency, and storage capabilities – all of which makes it ideally positioned to service primary workloads in the data center.

In this Technology Validation, we set out to examine StoreVirtual VSA, and through comparison to another leading virtual storage appliance (VMware’s vSphere Storage Appliance – VMware VSA) evaluate the effectiveness of StoreVirtual VSA’s architecture in enabling superior, primary-workload-ready storage in the virtual infrastructure.  With an eye on ease of use, efficiency, and flexibility, we put StoreVirtual VSA and VMware vSphere Storage Appliance through a detailed examination that included both a review of functionality and a hands-on lab examination of performance, scalability, resiliency, and ease of use.
