I need a San Solution with linear scalability in size as well as in performance.
From what I know, with a Modular Smart Array solution such as the P2000/MSA-class solutions from HP, even with a dual controller initial node, I can only increase the size of it, as added nodes come controller-less, so overall performance tends to decrease.
On the other hand, the P4000 (lefthand) family of solutions has each of it's nodes have it's own controller, and so when a node is added, storage capacity as well as performance increase.
Am I right in all that I say, and is the P4000 the only solution, or have I forgotten something ?
