Is there a best practice for choosing a raid type for local storage on blade servers? If you are installing ESXi locally, are most customers using at least a raid 1 configuration? Blades tend to have as few as 2 local drives - which means either 1 or 0. Is 0 too risky as the loss of one means the server goes down? Or if you have your blades in an HA cluster, is the performance gain of using raid 0 worth the extra risk?
Opinions?
Thanks!
