Cloud computing is part of the journey to deliver IT as a Service which enables IT to change from a cost center to a business strategic partner. Forrester Research recently published a report that concluded, “Cloud computing is ready for the enterprise… but many enterprises aren’t ready for the cloud.”1 Yet Cloud deployments are happening – and I mean all types of Clouds – Private, Public and Hybrid. In other words, we have entered the World of Many Clouds.
Network touches everything and is a key building block for agile and scalable virtualized and Cloud-based data centers. Yesterday, I have introduced our new Nexus 6000 series and new 40 GE extensions to Nexus 5500 and 2000 Series. Today, I would like to introduce the very first services module for the Nexus 7000 Series.

This week, as part of a major cloud launch that also introduced the Nexus 6000 series and updates to our Cisco ONE portfolio, Cisco unveiled its Nexus 1000V InterCloud solution, which provides a seamless and secure extension of virtual networks from on-premises data centers to cloud service providers. In part 1 of our introductory blog series to this new technology, we discussed the architecture and components of Nexus 1000V InterCloud for creating secure, on-demand virtual private cloud (VPC) containers in a hybrid cloud. In a pre-launch post earlier in January, we looked at some new Forrester research data on hybrid cloud business drivers and how some organizations were looking to overcome the challenges to real hybrid cloud integration. Today, in part 2 of our InterCloud series, we are going into more depth about the hybrid cloud management component, Virtual Network Management Center (VNMC) InterCloud.
VNMC InterCloud provides a single pane view of VM and cloud resources across the on-premises resources and those at the cloud provider. It interfaces to orchestration tools and service provider management systems, as well as virtual machine managers.

Welcome back as we continue to dive deeper into advanced CPU (Central Processing Unit – I had a “tech writer” change a document on me one time, he assumed at this day in age that people still needed to have the CPU acronym translated.. but I digress) and Memory concepts in the land of VDI. Last week Doron answered our first question and told us about Core Count vs. Core Speed for scalable VDI. This week we will focus specifically on Core Speed, bursting and introduce you to a potentially new subject called “SPEC Blend/Core” for high performance VDI. If you are just finding this blog post for the first time, I encourage you to check out the Introduction from Tony as it will help set the stage for our discussion. Here is the full table of contents:
- Introduction – VDI – The Questions you didn’t ask (but really should)
- VDI “The Missing Questions” #1: Core Count vs. Core Speed
- VDI “The Missing Questions” #2: Core Speed Scaling (Burst) YOU ARE HERE!
- VDI “The Missing Questions” #3: Realistic Virtual Desktop Limits
- VDI “The Missing Questions” #4: How much SPECint is enough
- VDI “The Missing Questions” #5: How does 1vCPU scale compared to 2vCPU’s?
- VDI “The Missing Questions” #6: What do you really gain from a 2vCPU virtual desktop?
- VDI “The Missing Questions” #7: How memory bus speed affects scale
- VDI “The Missing Questions” #8: How does memory density affect VDI scalability?
- VDI “The Missing Questions” #9: How many storage IOPs?

VM’s are only as fast as their individual cores! Lets look at what this statement means. Example: Assume we have a 1GHz x 4 core processor (hey, it makes math easy for me). When we carve up a server VM or in this case a VM to be used for VDI, we can’t just give it 2 vCPU’s and say it’s got a 2GHz processor. The reality is that it has a dual 1GHz processor. This becomes an important concept in VDI when you are considering the quantity and QUALITY of vCPU’s you allocate to a Virtual Machine and ultimately the end user applications efficiency and the overall scalability of the server platform. This is not a Uni-processor vs. Multi-processor application discussion. We could easily have a very long discussion and debate on the in’s and out’s of application level efficiencies and the Operating Systems ability (and sometimes inability) to properly manage multiple CPU’s. We are going to expand upon the two CPU’s we tested and dig into per core performance.
CPU Burst vs. CPU Reservation. Let’s play around with our example 1GHz x 4 Core Processor a bit more. If we take this single processor and deploy 8 single vCPU desktops on it we will have a 500MHz CPU reservation per VM. The calculation for that is simple 1GHz x 4 Cores = 4,000MHz / 8 total VM’s = 500MHz/VM Reservation. So the Reservation is simply the average amount of CPU that is available to each VM (assuming everything is prioritized equally). But our Burst is different. Our Burst represents the maximum amount of CPU Core that any one VM could ever utilize. In this example, the Burst per VM is equivalent to 1GHz.

In a recent post, I previewed some new hybrid cloud market research from Forrester that spoke to the business drivers and technical hurdles to cloud integration, and Shashi Kiran has recently posted about lowering the barriers to hybrid cloud adoption. Today, as part of a larger cloud technology launch, Cisco is announcing a new hybrid cloud solution, Nexus 1000V InterCloud.
One of the fundamental capabilities for the world of many clouds is the ability to link various cloud environments into a single extended fabric with consistent capabilities, operations and management. While previous Unified Fabric innovation has focused on physical/virtual consistency of the DC fabric, this announcement brings that consistency to the cloud. This new technology from Cisco extends the existing networking capabilities, L4-7 services and manageability of your enterprise into public and provider clouds to create a single consistent, reliable, predictable environment for all your physical, virtual and cloud workloads. This secure and seamless degree of integration to the hybrid cloud frees you to run and move applications where it makes the most sense, on-demand, without compromise.

Cisco Unified Computing System Service Profiles and Templates contain over 127 different server identification and configuration settings. These identity settings are abstracted from the physical server and stored in the UCS Domain where they can be leveraged automating and speeding deployment while reducing errors. Today, this Cisco innovation is still unique in the industry. The reality is that no other server vendor can offer the level of hardware abstraction that Cisco provides with UCS Manager using Service Profiles and Templates.
Unlike Cisco, other vendors must rely on many different tools and methods that are cobbled together to manage their servers. For some, it can take up to six different tools to configure a subset of what Cisco can do with one and most of these tools are at an additional cost.
Are you concerned about systems management and how it impacts your total cost of ownership (TCO)? Here are some fair questions to ask your current vendor:
- Can your software templates manage both rack and blade servers using a single tool and interface?
- Are your templates and profiles limited to specific models and only certain generation of servers, requiring different templates or tools for the same settings for servers from different generations of the same server model?
- Is server firmware truly integrated into a single tool and supported by policies and profiles?
- Do the tools use only proprietary orchestration and automation software to manage the infrastructure or does it support an open interface like XML?
- What is the licensing model – how much is the additional cost per server or per blade chassis to fully manage server profiles, updates to firmware, BIOS, and integration with other tools?
If you have more than one domain, UCS Central will manage them extending all the benefits of UCS Manger globally. You can leverage your templates and profiles across all servers regardless of location.
