Good read on why not " NeverGet Advice from a Reseller"
I am looking to expand our SAN storage -either get same storage or a new vendor- and came up on this article. I wish I would have seen/read this article couple of years back, when we went straight to EMC for the storage, rather than shopping around. It's not like i am regreting our VNX5300
