During this years VMworld I was so lucky to get a signed hard copy of the vSphere Design Pocketbook. It is a vSphere design book in with all its design recommendations in “tweet factor”. The book is sponsored by Pernixdata
The good news is that if you did not go to VMworld you can have the book for free as an ebook. Just sign-up here
The book is written by top bloggers and people from the virtualization community. I highly recommend it.
