Over the past 2 months or so, I’ve been blogging on Cisco Domain TenSM, Cisco Service’s framework to guide you on your path to data center and cloud transformation. We are just over half way through the discussion on Cisco Domain Ten, so I thought it worthwhile, especially for anyone reading about this concept for the first time, to write a quick refresher and summary of the articles I’ve written so far. So forgive the brevity and please do dive into the links/URLs for more information if indeed you missed these articles first time. And if you’ve read every article -- thanks!
Years ago, it was enough for partners to supply, install, and maintain a customer’s network assets. But in the era of service delivery-based solutions, customers are increasingly asking partners not only to supply their network infrastructure but also to manage it –and do so in a way that’s both consistent and efficient.
With that customer conversation shifting toward services and management, how do you best respond to these customer requirements and what solutions are out there to help you?
Fortunately, as a Cisco partner, you already have access to a tool that contains all of the information you need. When you log into Cisco’s Services Accelerate Program, you’ll find services sales training and incentive programs available to help you grow your Cisco Services business and earn rewards to accelerate your success!
This six-part series focuses on transformation of the traditional higher education system in the United States. This part focuses on the fact that universities are more similar than they are different. Universities in the U.S. share common challenges: inadequate access, dated teaching methodologies, and perceived irrelevance of our current programs.
First, we have a problem of access: We simply do not have enough capacity to meet demand. In the U.S., there were 3.2 million graduating seniors in the class of 2012, 73 percent of whom believed they needed still more education to obtain higher-paying jobs. Since 2007 the number of international students has also increased by more than 20 percent. And, competition is increasingly stiff for places in top academic universities: Harvard accepted only 5.9 percent of applicants, and Yale accepted 6.8 percent. With only 4,000 higher education institutions in the U.S., it’s easy to see that we lack the capacity to continue delivering against the increase in demand.

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:
In case you missed it, Network World’s Ellen Messmer published a rather surprising article on how Dell was going to “trump” Cisco in the information security market as a result of some recent acquisitions. Now certainly Dell is entitled to their beliefs. They’re in a difficult position right now, as Michael Dell and Silver Lake maneuver the company through a very complex set of buy-out related transactions. They need to give their customers assurance that they won’t be distracted through this process. And if you want to set a big impression with your customers, you might as well go after the market leader in security. Be it as it may, we can’t just sit back and let these blatant statements go unchecked. So, in the spirit of “fair and balanced” reporting, we thought we’d issue our own little fact check and let you conclude for yourself.
“Cisco is a great competitor but they don’t have our holistic view” – Acquiring assets and bundling them together doesn’t constitute a “holistic” approach. Those assets must be closely integrated, which is the approach Cisco is delivering with its next generation security architecture. This architecture will be built on top of a multi-function security platform with deep network integration. There are many proof points today that demonstrate we are delivering against this strategy and architecture. Today our customers are deploying Cloud Web Security with their Cisco ISR G2 and ASA Next Generation Firewall through connectors built from Cloud Web Security. In addition we’ve brought market leading application, visibility and control to ASA, embedded deep in the firewall. But it doesn’t stop here.
Now what about Dell’s comment that Cisco “doesn’t have an identity business“? Cisco’s Identity Services Engine provides the backbone of Cisco’s secure Unified Access solution. The real network security action is in delivering access privileges based on more than just user identity and group which is all Dell can do today with Quest. In the BYOD world customers also require action based on the type of device, posture of the device, and location. Cisco’s Identity Services Engine is the industry leading platform to deliver context based policy controls and then leveraging the network for distributed enforcement consistently across wired, wireless, and VPN access. This is a game-changer for the enterprise and our next generation end-to-end security architecture. Enterprises can now implement context-based policy from the access layer through the data center switching fabric without using brittle and costly network segmentation methods tied to VLANs and ACLs. This is real synergy, and it is delivering a holistic solution as opposed to a holistic press sound bite. But don’t just take our word for it; check out Gartner’s latest Magic Quadrant for NAC. Cisco’s ISE combines identity, device, and network with a market leading platform deployed in over 3000 customers.
Just weeks ago we announced another key milestone with the introduction of ISE 1.2. With this latest release we also became the first vendor in the industry to offer automated profiling feeds making us better and faster at identifying new devices and operating systems. We’ve increased the speed and scalability of ISE to address the increasing demands brought on by the “Internet of Everything”. And we’ve added a new set of partner APIs enabling integration into key MDM partners – SAP, AirWatch, Citrix, Mobile Iron and Good. This expands the reach of ISE and enables customers to drive common context and identity management from the network all the way to the end point. Dell talk’s about their direction to advance the “concept” of embedded security to virtually any type of device. We’re not just talking about it, we’re doing it. Read More »
