Recently I had the privilege to be selected as a contributor for the new vSphere Design Pocketbook v3, published by Pernixdata, where IOs are eaten for breakfast.
As the name implies this is the third edition of the book, each one with a different format.
First one had many tweet sized recommendations, the second on included longer posts on design and technical components while this third one is a mix of both.
The social edition, or the online edition only with more fancier name, can be downloaded right here. A physical copy will probably be available at various trade shows where Pernixdata has a presence.
Even as biased as I am I recommend picking up a copy for you and all your closest relatives, cause they will love you forever when you send them a copy. (results may vary).
And as a PernixPrime I also recommend you to check out Pernixdata based on their slogan: “Keep you CPU and memory close, but your IOs even closer”. (this is not their slogan and should be regarded as nonsense).
