I thought we'd disabused you of the notion that you need a [high end] SAN? Granted the high end ones are nice and they have their uses, but your just looking to store files on it. Are you going to virtualize all your servers, rely on Vmotion or some other tool to ensure high availability, or do you need to provide data access to a large number of disparate servers? Consider looking at some of the lower end offerings from Synology and Qnap (heard good things), and avoid Drobo (heard not so good things) and stay away from Buffalo (don't touch that, it's pure evil).
This "project" has been on your dockett for over a year now, hasn't it? Awaiting funding? The Synology and Qnap offerings are pretty affordable, and get you into iSCSI access realm. Also, whatever happened to your project about setting up your own storage server? With Windows Server 2008 R2 having access to the iSCSI target software MS recently released, that becomes an option now, too.
