OTV Optimal Routing

Posted by: Pete Welcher on Apr 28, 2010

Pete's faceTwo prior blogs discussed OTV, Cisco Overlay Transport Virtualization. One of those blogs pointed out some concerns one might have about optimal routing, OTV optimal routing. (My virtual machine -- VM --  moved to the other data center -- does inbound / outbound traffic do the right thing?) A reader (thanks!) shared a good link, and that motivated me to find some Cisco-centric answers as well.

CMUG: Data Center Virtualization

Posted by: Pete Welcher on Apr 27, 2010

In this CMUG session, I discussed "Data Center Virtualization" at the April C-MUG session. We looked at the many aspects of virtualization that are relevant to the data center, sharing many ways in which the data center is changing, and presenting some design approaches that you may find useful in your own data center. Major portions of the talk looked at the following topics:

Exploiting Layer 2 over Layer 3

Posted by: Pete Welcher on Mar 5, 2010

Pete's faceThis is part 3 of a series about Layer 2 over Layer 3, although I changed the titling somewhat. This blog takes a look at a very practical application of some of the Layer 2 (L2) over Layer 3 (L3) techniques discussed in prior articles. Specifically, how L2 over L3 can help with server relocation and re-addressing, especially in VMotion form.
