I was doing some reading this morning on the new MDS 9710 Director Class switch and came across a feature I hadn’t heard of before. The feature is called “Smart Zoning” and is a real godsend for SAN and data center administrators.
I happened across an interesting scenario this morning while I was doing configuring jumbo MTU of 9216 on the Nexus 5500 switches in our lab.
I wanted to enable jumbo frames and with Nexus 5500s you have to do this with a QoS policy map. Here are the steps:
- Create a new policy map of type network-qos
- Add the default network-qos class type of class-default
- Configure the MTU to 9216
- Add the new policy map to system qos
See my post on configuration and migration to multihop FCoE for details on my lab setup – https://jeremywaldrop.wordpress.com/2013/04/11/cisco-ucs-fcoe-multihop-configuration-and-migration/
When I first configured UCS multihop FCoE I experienced terrible SAN performance. It was so bad that it took 20 minutes to boot a single virtual machine.
This post will walk through the configuration of FCoE multihop in UCS and cover how to migrate from traditional FC to FCoE.
