VDI “The Missing Questions” #4: How much SPECint is enough

February 25, 2013 at 6:35 am PST

In the first few posts in this series, we have hopefully shown that not all cores are created equal and that not all GHz are created equal. This generates challenges when comparing two CPUs within a processor family and even greater challenges when comparing CPUs from different processor families. If you read a blog or a study that showed 175 desktops on a blade with dual E7-2870 processor, how many desktops can you expect from the E7-2803 processor? Or an E5 processor? Our assertion is that SPECint is a reasonable metric for predicting VDI density, and in this blog I intend to show you how much SPECint is enough [for the workload we tested].

You are here. As a quick recap, this is a series of blogs covering the topic of VDI, and here are the posts in this series:

Addition and subtraction versus multiplication and division. Shawn already explained the concept of SPEC in question 2, so I won’t repeat it. You’ve probably noticed that Shawn talked about “blended” SPEC whereas I’m covering SPECint (integer). As it turns out, the majority of task workers really exercise the integer portion of a processor rather than the floating point portion of a processor. Therefore, I’ll focus on SPECint in this post. If you know more about your users’ workload, you can skew your emphasis more or less towards SPECint or SPECfp and create your own blend.

The method to the madness. Let me take you on a short mathematical journey using the figure below. Starting at the top, we know each E5-2665 processor has a SPECint of 305. It doesn’t matter how many cores it has or how fast those cores are clocked. It has a SPECint score of 305 (as compared to 187.5 for the E5-2643 processor). Continuing down the figure below, each blade we tested had two processors, so the E5-2665 based blade has a SPECint of 2 x 305… or 610. The E5-2665 blade has a much higher SPECint of 610 than the E5-2643 blade with just 375. And it produced many more desktops as you can see from the graph embedded in the figure (the graph should look familiar to you from the first “question” in this series).

And now comes the simple math to get the SPECint requirement for each virtual desktop in each test system:

VCE: Converging on a better data center

Cisco’s Unified Data Center strategy is rooted in the idea that customers shouldn’t be put in the position of DIY technology integration.  It’s just an unfair ask given everything that IT and LOB leaders contend with above and beyond the infrastructure.   As technology has evolved, the component parts of the data center are decreasingly the source of complexity.   It’s the connections between them, creating that sum of the parts that can actually run applications, that’s the hardest part.   Eliminating this complexity has been Cisco’s guiding star in the data center, building systems that help customers focus on what matters most to them:  applications and IT services, not infrastructure.

VCE, Cisco’s joint venture with EMC, VMware and Intel, is a critical expression of this vision for fabric based infrastructure and converged solutions.  Today marks a major milestone for VCE with the broadest solutions announcement since the launch of Vblock Systems, which has become widely recognized as the gold standard of converged infrastructure.

These new offerings extend the proven value of Vblock: converged, pre-engineered infrastructure that slashes deployment time and ongoing management burden, into a new set of market segments and key workloads.

The team at VCE have done a great job detailing this out; I see the key components being brought forward today as:

• Taking Vblock Systems to new customer segments and use cases:  System 200 is designed for mid-size data centers and service provider-managed customer premise (CPE) scenarios.  System 100 extends to remote office/branch office environments.  Combining these new Vblocks with applications like  Microsoft Exchange & Sharepoint, VDI, and Cisco Unified Commuications will continue the push to eliminate DIY solution assembly for customers.
• VCE Specialized Systems: a series of systems optimized for key workloads, starting with SAP HANA.  Certification for Vblock here is an exciting new opportunity for customers to quickly adopt this hot new analytic technology
• VCE Vision Intelligent Operations which brings intelligent discovery and single lens management to VBlock Systems.  This takes a similar API driven approach found at the core of UCS to enable orchestration of the converged system.   This is a critical component for cloud builders.

VCE’s launch is a major milestone in their evolution, but the way each Vblock system is built, maintained and supported remains constant and predictable. Customers can continue to rely on the same comprehensive physical and logical build done in the factory, single point support and the IT agility and economic benefits these create.

Customers have spoken and this is being reflected in the results, with 1,000 Vblock Systems shipped, demand on a billion dollar run rate and recognition as the market leader in converged systems.

Congratulations to the VCE team as they continue to make it easier for customers to concentrate on the business and not on the infrastructure!

Cisco and VMware Teaming-Up to Accelerate VDI Uptake in 2013 – Join us at VMware Partner Exchange to Find Out More

Are you a Cisco/VMware partner going to VMware Partner Exchange (PEX)?  In Vegas!  Next week!  If so, and you’re focused on growing your VDI practice, there’s some great content for you to take in while there.  Before I get into PEX, let me remind you about our on-going blog series, “VDI -  The Questions You Didn’t Ask (But Really Should)”.  We’re up to Question 4 (coming soon), and if you’re looking for some great insights into the mystique of processor selection and impact on VDI performance/density/etc, this is the series for you!  Now onto PEX…

Improving the ROI of VDI within small and medium-sized organizations

Next week, we’ll be updating our VMware partner community on new solutions that offer an accelerated path to growing their VDI practice, especially for smaller deployments, as found in small and medium sized businesses (or pilot / proof-of-concept environments), where the up-front CAPEX hurdle is often too much of a barrier to make VDI cost effective.

New Ecosystem Solutions Portfolio

In tandem with VMware, we’ll be announcing a new portfolio of solutions built with ecosystem partners helping to deliver better VDI price-to-performance ratios, greater operational simplicity, and uncompromised user experience, built on Cisco UCS with VMware Horizon View.
