Lots of us have Storage Area Networks (SANs). Most of us, probably. How do you go about optimizing for speed? How many spindles do you have? iSCSI or FC? How do you break up your array? And if you have an EMC SAN, what do you do with the first four drives that share the stupid Flare OS?
Looking for input from anyone who has put effort into speeding up their SAN to make disk access more timely and reliable.
