When we talk about networks in the data center, there is often talk about bandwidth, 10Gigabit Ethernet, switch sizing, and the changes that have been wrought on the network since the inception of widespread server virtualization. The base operating system that the switch runs on, the networking software itself, is often only discussed in terms of how/when/why to do upgrades. Networking software has more relevance than that, especially from a strategic standpoint.
The strategic nature of networking software is easy to see. But the most important way networking software is important is in the flexibility it can provide over the lifetime of the product line. Poorly written or architected networking software can put a huge burden on the vendor when new features or when major changes to the networking industry occurs. As a customer that matters because the vendor may spend the time and money to accommodate those changes or has to charge an exorbitant amount. It all speaks to the investment protection a vendor can bring. Poor network software equals poor investment protection and a degraded upgrade path.

Data Center Connections using “nV edge”
The ASR 9000 product family has recently come out with a new feature called nV Edge (nV = Network Virtualization). This feature unifies the data center edge control, data and management planes. So, I’ll note a couple things here on this feature and then tell you why I think it has potential to be truly awesome.
My good friend Rabiul Hasan just wrote a proof of concept document just posted to Design Zone that provides the configuration and setup details. I encourage you to go check it out here.

Cisco continues its cloud computing performance leadership with the announcement of VMware® VMmark™ 2.1 benchmark result published on July 10th 2012.
The Cisco UCS B200 M3 Blade Server’s score of 11.30@10 tiles on the VMware VMmark 2.1 benchmark outperforming all other 2-socket blade servers. The world-record score demonstrates how well a system’s servers, network, and storage components support virtual machine movement, storage migration, and virtual machine provisioning.
First generation VMmark (VMmark 1.x) was a server consolidation workload. It measured how many VMs that can be run on a single server. VMmark 2.x is the next generation benchmark from VMware that was introduced in December 2010. The VMmark 2.1 benchmark uses a tiled design that incorporates six real-world workloads to determine a virtualization score. Then it factors VMware vMotion, Storage vMotion, and virtual machine provisioning times to determine an infrastructure score. The combination of these scores is the total benchmark score. Because Cisco UCS is a truly unified system, it delivers both virtualization and infrastructure performance.

In my journeys of talking to IT organizations I come across individuals who really stand out in their drive and passion to transform their organization and achieve a pragmatic cloud for their stakeholders. This is the second in a series of Blogs on the Superheroes of the Cloud. What makes these individuals and their organizations special is that they distinguish their organizations by having a unique angle to their Journey to the Cloud. I won’t spell out the exact formula but I will offer some tidbits on why I am impressed by these superheroes.
The move to the cloud and the force of that current has surprised analyst, vendor, and customer alike. We at Cisco believe in a strong Partner Ecosystem to support our customers in their journey. Four years ago we had probably a dozen experts in Intelligent Automation Software on the planet. Today that number probably exceeds 200 and will be soon be above 1000. We are actively training and enhancing expertise at our IA for Cloud partners so that they can help their clients leverage the value of our cloud stack.

This will probably be my shortest blog ever! Perhaps it is really a bloglet, whatever the case here’s what I’m doing. A question was posted in the Technical Discussions forum of the UCS section of the Cisco Developer Network
I have an environment consisiting of 20+ chassis … I’d like to be able to get the number of open blade slots on each of these.
I’m sure there has to be a command i can put together for this.
Here’s my response:
