I was considering setting up servers, with the data disk being raid 0.. since we have a replica on another server.. I figured that would a good way to save a lot of money (SSD's is by far the most expensive part of a new cluster setup).
I figured I'd use 1TB disks - and have approx 10 pcs. per server.. that ofcourse means that the risk of failure is ~X10.. since only of the 10 disks needs to fail, for the entire servers datastore to fail.
Does anyone have any experience with doing that.. or is it just a stupid idea?
