My personal adventures in the quest for virtual perfectness.
I just got quite excited about the fact VMware's PowerCLI 5.5r2 release. For me it's the full tag support.
Maintaining a large vSphere environment can be challenging at times and trying to keep a good overview is crucial. Using tags (in the previous vSphere versions you could use 'Custom attributes') can help significantly. Some examples you can put in tags, things like: bladechassis name, slot, link to CMDB, installed by, special usage, etc. etc. I cannot wait to go to work tomorrow and check it out .
Anyway, for full information check the release note: http://blogs.vmware.com/PowerCLI/2014/03/new-release-vsphere-powercli-5-5-r2.html
