So what exactly can you do in 16 minutes? Well, you can:
- Download and install your preferred tax prep software, because (if you’re in the US or Canada) April is coming
- Enjoy your 15 minutes of fame, then reminisce and/or lament about it for exactly 1 minute.
- Save 15% on your car insurance (you can supposedly get this done in 15 vs. 16 min.)
- Do some really unsavory things not suitable for mentioning on a nice blog post like this one.
Don’t care about any of those things? Neither do I. Let me come back to this in a moment…
If you’re familiar with our architecture portfolio for desktop virtualization, you may be aware that we’re continuing to invest in VSPEX-based reference architectures for Cisco Desktop Virtualization. This week, we just announced the latest addition to the Cisco Validated Design (CVD) portfolio – our solution for VMware Horizon View 5.3 with Cisco UCS and EMC VSPEX available here.
If you’re not already familiar with them, CVD’s provide prescriptive design guidance around how to build solutions with specific outcomes (performance) as documented through a testing/documentation discipline that Cisco’s been doing for years. You’ll find our repository of desktop virtualization CVD’s here.
So now let’s talk about the CVD itself. Our principal author is Ramesh Guduru – he’s a Virtualization Systems Engineer in Cisco’s Data Center Business Group and has extensive experience in Horizon View, virtualization infrastructure and management, Cisco UCS and storage. Ramesh assembled a test platform based on the setup shown in Figure 1.
Figure 1: Cisco CVD Validation Platform
As you can see the core pillars of the solution are:
Key things we wanted to expose/profile in this effort included:
- More with less – more powerful processors and faster memory
- System footprint for delivering 2,000 Horizon View desktops, while still retaining room to expand as demand increases
- Leverage more economical processors – ex: a 57% lower list price for the Intel E5-2680 v2 10-core processors vs. top bin processors tested in the past = lower server cost = lower per desktop CAPEX
- Hosting density leadership (# desktops per compute blade)
- End user experience as exercised using LoginVSI with medium workload with Flash
- Boot-up and login performance (simulating the Monday-morning boot storm dilemma all VDI implementations face and daily login storms)·
From a design perspective we also wanted to ensure our system provided:
- Full n+1 fault tolerance across the stack
- Fully virtualized platform, inclusive of the virtual desktops, as well as the infrastructure componentry like vCenter, AD, SQL servers etc.
I’ll leave it to you the explore the methodology Ramesh followed for the CVD, but let me point to a couple interesting things gained from this effort:
- With our B200 M3 blade, we increased our desktop workload capacity (across the system) by 30% compared with full-width blades used in prior analyses
- We collapsed the footprint from 30 RU down to just 12 RU.
- The combined effect of the selected CPU (Intel Ivy Bridge), high-bandwidth, low-latency unified fabric, and our VIC 1240 converged networking adapter yielded exceptional user experience at under 1.75 sec at full load.
- The EMC VNX5600 provided outstanding storage performance for both file and block, using EMC Fast Cache technology.
- VMware Horizon View 5.3 with Sparse Virtual Disk gave us better disk performance and disk space efficiency.
And as for the 16 minute thing?
- That’s how long it took for the full population of 2,000 virtual desktops to get booted and ready to login (under 16 minutes). And in an additional 14 we had all of them running user workload with no sign of exhausting the system.

You may have caught this week’s announcement from Citrix on the availability of XenDesktop 7.5 (see announcement here). With this release, desktop virtualization implementers can tap into new elasticity and efficiencies of provisioning, managing, and scaling-up/down their deployments in real time, while also tapping into the simplicity and performance of Windows app delivery with XenApp 7.5 .
If you’ve followed Citrix and Cisco’s journey in this space, you know that our two companies enjoy an extensive track record of collaboration and innovation in breaking down the CAPEX, complexity and performance barriers associated with delivering virtual workspaces to users, on any device, anywhere. We’re continuing to innovate on this front, bringing together a combined vision and architecture for desktop virtualization and enterprise mobility. Cisco and Citrix continue to accelerate the ROI and performance of desktop virtualization, and are making it easier than ever for environments of all sizes to get into VDI and app virtualization quickly and cost-effectively. Our new Solution Accelerator Paks for Citrix XenDesktop are a great proof point of that.
I want to now turn to a couple concepts that are central to this latest announcement. The notion of an elastic infrastructure approach for these deployments, that straddles public and private cloud to enable ‘capacity-flexing’ in terms of virtual desktop scale. If you look at the underpinning, you see this notion of stateless, elastic provisioning present in the very core of our joint solution – the Cisco Unified Computing System (UCS).
Give UCS Manager a Test Drive
The DNA of the UCS architecture is based on answering the question “how would you build a server to deliver a pervasive virtual infrastructure that flexes in real time to changing, shifting workload capacity demands?” Cisco answered that question four years ago with a compute platform purpose-built to deliver the goods, founded on our stateless provisioning and operations model. This wire-once, touch-less environment for flexing desktop virtualization capacity up and down, is a foundational pillar for the Citrix announcement. If you haven’t had a chance to test-drive UCS Manager and Service Profiles, check out the UCS Advantage.
Equally important is the reality that our customers need and want a balanced portfolio approach to how they consume IT services both via the public and private cloud. This hybridized approach provides insulation, security, and eliminates dependency and risk associated with any one delivery model. This is central to Cisco’s “World of Many Clouds” – and on that note you may have seen the news coming out of Cisco Live Milan on Wednesday January 28th – available here.
If you’re at Cisco Live Milan this week I encourage you to stop by our Data Center booth and learn more about:
- UCS provisioning and management of workloads like VDI and app virtualization
- Desktop virtualization solution architectures with ecosystem partners
- Cisco UCS Invicta delivering accelerated VDI performance
- Much more

As you may have seen in the announcement on December 17th, Cisco along with its partners Citrix and Desktone by VMware, are announcing our joint solutions for Desktop-as-a-Service (DaaS). Clearly our customers demand choice and flexibility in how they choose to implement desktop virtualization, not just in terms of the delivery technology, but also in terms of the ownership model. You’ve told us you want virtual desktops and apps that fit your business and IT consumption models. You want it “your way”. And for a growing constituency, it just makes sense to shift the burden of designing, implementing and managing the solution to an affordable OPEX model, outsourced to a Cisco-powered Service Provider. Cisco DaaS offers our customers the choice and flexibility they expect.
What you may have also noticed with this announcement is that Cisco and its partners are continuing to bolster the underlying infrastructure/fabric of our desktop virtualization platform, to the benefit of both our premises-based and cloud-based (DaaS) clientele. To that end, we’re sharing some important enhancements we think make the overall platform an optimal underpinning for virtualized desktops and apps.
Raising the CPU Performance Bar
The Cisco UCS B200 M3 Series Blade Server continues to be our flagship VDI workhorse delivering industry-leading performance for virtual desktops and apps. We’ve updated this server to incorporate the latest Intel Xeon E5-2600 v2 Series Processors (Ivy Bridge), and with that we’ve delivered unprecedented performance gains. For example, based on single-blade characterization testing conducted by Cisco, and using the industry-recognized LoginVSI for workload testing, we’ve successfully deployed 252 VMware Horizon View desktops on a single blade (based on LoginVSI Max threshold). This represents a 31% increase in server hosting density over the previous CPU.
The Economics of Flash
Nowhere is the benefit of flash technology seen so forcefully as with VDI workloads where the IOPS bottleneck has traditionally driven the up front CAPEX hurdle of desktop virtualization, out of reach for many environments, especially smaller ones. Cisco has worked extensively with our portfolio of industry-leading storage technology partners to continue to offer prescriptive design guidance on how to tap into the benefits of the flash and hybrid-flash arrays.
Nimble Storage has been a featured joint solution on which many of our customers have experienced the economics of this hybrid-flash solution first-hand. Many organizations are increasingly tapping into the efficiencies of this solution in conjunction with Hosted Shared Desktops (ie: Citrix XenApp), for which we’re announcing a brand new reference architecture based on Nimble’s CS240G-X4 with Cisco UCS, Citrix XenApp 6.5 on Microsoft Hyper-V. The Citrix Validated Solution supports 1,000 hosted shared desktops running on the Nimble array. The compact 3U solution provides cost-effective performance and capacity through its flash-optimized hybrid storage architecture, that combines the exceptional performance of flash with the favorable economics of high-capacity disk. The validated architecture allows customers to eliminate risk, speed time to deployment, and scale as needed using the modular design.
Making Physical and Virtual Indistinguishable: Immersive Graphics
You may have caught my blog in support of the Citrix/NVIDIA/Cisco joint solution announcement on Dec. 11th. Similarly, customers like SSOE are reaping the benefits of our joint solution with VMware and NVIDIA. It’s no surprise that end users need (no, demand) that their virtual environment behaves akin to the physical one they left behind. Just talk to any designer, healthcare clinician or researcher in an academic setting. This has been one of the stumbling blocks around expanding the number of use cases that can be targeted by VDI, specifically where graphics-intensive applications are used.. I encourage you to learn more about our joint solutions with VMware and Citrix
Accelerating the ROI of VDI and App Virtualization – It’s All in the Bundles
To close this out, I want to shift focus to the “last mile” problem of the journey to virtual desktops. No, not the “networking” last mile, but rather that point at which you’ve made the determination to implement a solution, to get your feet wet, ie: how to get started.
Earlier this month, Cisco released brand new Solution Accelerator Paks for Desktop Virtualization with VMware and Citrix. These bundles offer attractive discounting, along with single-SKU ordering simplicity. Organizations seeking to get into desktop virtualization can take advantage of Solution Accelerator Paks to deploy small pilot or proof-of-concept environments that offer great scalability when the need arises.
These bundles also offer expansion and upgrade options for adding more users, tier-0 flash storage from Fusion-io and LSI, as well as GPU options based on NVIDIA GRID K1, and K2. Check out our brochures for VMware and Citrix as well as the ordering guides if you want more detail (VMware , Citrix )

The VDI landscape is increasingly evolving to embrace virtual desktops that look, perform, and respond like their physical predecessors. Whether it’s application responsiveness with low latency across the network, or high-performance storage with expansive IOPS capacity that mirrors the native experience on one’s desktop/laptop, implementers and users expect their virtual desktops to behave akin to physical.
These technological achievements have led to increasingly successful virtual desktop deployments for knowledge workers and task workers, but not so much so for users of 3D graphics applications traditionally running on high-end dedicated graphics workstations. Across many industries and verticals like Manufacturing/Design, Higher Ed, and Healthcare, you’ll find end users needing access to immersive 3D graphics applications.
Cisco, Citrix and NVIDIA are pleased to be at the forefront of extending the applicability of VDI for graphics-intensive use cases, enabled by our jointly validated solution architectures based on Cisco Unified Computing, NVIDIA GRID™ vGPU™ and Citrix XenDesktop. This joint solution offers affordable, scalable performance for graphics-intensive VDI use cases, built on an optimized computing infrastructure from Cisco. Cisco Unified Computing System (UCS) is the foundation of Cisco Desktop Virtualization Solutions. Cisco UCS provides an end-to-end, service-and-application optimized platform for mobile, virtual workspaces. The embedded NVIDIA GRID solution enables GPU sharing without sacrificing application compatibility or the user experience. Citrix XenDesktop and XenApp deliver desktops and applications as on demand services that tap into the benefits of GPU resources. With our combined desktop virtualization solution, we’re expanding the utility, reach and performance of VDI.

It’s a beautiful thing when you can hijack four not-quite random people off the VMworld show floor and get them to tackle a discussion on desktop virtualization. And that’s exactly what we did a couple weeks back, when the opportunity presented itself. With Courtney Burry (VMware), Mike Brennan (Cisco), Dave Kinsman (WWT) and myself on hand, we did a sort of VDI blogger “round-up”. You should check out the video below, but a quick recap as follows:
- Courtney discussed some of the latest improvements in Horizon View that improve desktop TCO by optimizing storage footprint through technologies like SE sparse (or Space Efficient Sparse) which provides the ability to reclaim blocks of storage that are unused or deleted by the guest file system.
- I also shared some thoughts on our joint solution with VMware that’s expanding the number of use cases addressable by VDI, through our support of hardware-accelerated 3D Graphics with nVidia as part of our C-Series rack server solution, as well as the improving economics of 1:1 persistent desktop images using the latest generation of flash-based partner technologies we support through our VDI storage ecosystem.
- Mike discussed how we’re offering a more consolidated management approach with VMware through things like integration within vCenter which includes a snap-in for UCS, allowing administrators to see our UCS infrastructure inside the vCenter web client as well as open API’s that introduce more opportunities for automation, which combined with combine with UCS Manager and our automation tools, can help our customers provision desktops from bare metal, much faster.
- And to help round-out the round-up, we snagged Dave Kinsman from WWT, to give us his feedback on how he sees all of this coming together, both for channel partners like WWT, and they customers they serve.
