Within the past couple of months we have had two major crashes of our virtual infrastructure.  After the first crash we made some changes and moved our production vCenter servers to a management vCenter on separate hosts and our test vCenter servers to our View vCenter and our View vCenter servers to our production vCenter.  This allowed for a lot of separation of our vCenter’s, but also a lot to keep track of when our second crash occurred and we had to figure out where everything was located to start bringing up guests.
So I decided to make a nice diagram to keep in our data center to make things a little clearer on what our infrastructure looks like.  I found some cool Visio stencils for VMware here http://communities.vmware.com/docs/DOC-11498

 

I have not used them yet but I will keep you posted on how my diagram comes out.
