I got evolved in the past few months in designing and implementing large VDI solution, that will be weird for an Exchange MVP but I love the virtualization technology and couldn’t resist the temptation.
one of the most ugly parts of the VDI project is the storage design, in fact every VDI architect knows that storage sizing is one the painful aspects and one of the most critical parts for the VDI deployment success.
I spent hours trying to figure out the best model for the IOPs and Storage calculations for best and optimum user experience, and through hundreds of documents from Citrix, Netapp and Microsoft I found my method.
to start here is a nice link that will help you understand how things will go and spare the time of re-explaining the process
to better know Citrix’s Side of the story (watch out, the CTX holds a lot of netapp’s data although that it doesn’t use or recommend netapp) http://support.citrix.com/article/CTX130632
and finally we see a closer look to storage performance from netapp, I have to say that this is one of the most well written documents concerning storage, storage performance and storage reporting, the document can be read here
what I really loved that the report says that storage performance goes into several stages of its life cycle within the VDI project. the biggest IOPs hits are received during the first login attempts which is displayed in table 11 in the TR:
what made me excited that I developed my own IOPs predictor that I used for my projects, gladly my calculation were less than 1000 IOPs difference than the actual testing WOOOOOOOOOOHOOOOOOOOOO
I will put the calculator under further testing and it should be published later this month.
have a nice VDI sizing.
