Testing Cisco's Media-Centric Data Center
The tests documented in this report showed us that Cisco has a clear plan for its data center products. Service providers have to expand their service offerings to both residential and business customers to stay competitive and to increase their customer retention. While the network is the backbone of these IP video deployments, the data center is the brains. Without content, the backbone is going to be a pretty boring place.
So service providers, having to accommodate the plethora of services and the disk-space-hungry applications, must extend their data centers, and we saw that Cisco is positioned to support their needs. The Cisco story here is clear: First migrate to storage area networks and run your applications over the network. Then, since you’re already using SAN, why not use some of the virtualization options in the market and, while you are at it, be "greener." Next, you can make the lives of your operations staff simpler and, with two control plane modules in your data center switches, you will be able to enjoy hitless software upgrades and won't lose valuable services revenues when the control plane fails.
IP video applications are much less accommodating than best-effort Internet applications. A failure anywhere in the path between the application server and user is a potential cause for a torrent of calls to the support hotline. It is reassuring to see that Cisco has considered the complete path in its IP video solution.
An operator can never know who is watching an IP video program in the middle of the night, exactly when the “maintenance window” is open. These days are now gone and they are not coming back. The services have to be up and running, and the subscribers or businesses depending on them will show much less sympathy to the provider having to upgrade code or experiencing failures. So Cisco’s high-availability options seem to fit well with the service requirements.
We would have loved to spend more time with the data center systems and run them through rigorous FCoE and Ethernet tests. With Spirent’s recent Virtual TestCenter announcement (sadly, a month too late for our testing) one can imagine a whole new set of virtualization performance and scalability testing. We sure hope that in the next testing campaign we will get to explore these aspects in depth.
