VMware has released a design guide for a network with NSX, Cisco Nexus 7000 and Cisco UCS computing. Perhaps it’s a small glueing attempt from VMware to Cisco, maybe it’s nothing. The thing is, I’m really happy about this design guide, there’ll be a FlexPod for NSX yet! 😉

Read it here: http://www.vmware.com/files/pdf/products/nsx/vmware-nsx-on-cisco-n7kucs-design-guide.pdf

The document outlines a few important tips:

  • Use separate links for the routing between NSX and the Nexus switches. As you don’t want to route over vPC. 
  • Use DVS network shares to prioritise your traffic.
  • Make sure your MTU values are set properly.

It’s a very good read and goes deep into the details of designing and configuring NSX on a Cisco UCS platform with Cisco Nexus switches. The proposed Nexus 7ks are easily swapped out with Nexus 5ks (with L3 module, mind the limitations), so it already fits into the FlexPod design. Now only VMware and Cisco need to make nice and make it official and supported.

Share the wealth!
