For those who are interested in some of the options out there.
DIY DAS:
Supermicro 36 bay case - $1800
Promise 16 bay JBOD VTrak J610sD - $3700
Promise VTE610sD - $7500 (SAS attached head unit with onboard raid controllers,
takes JBOD expansion)
The following apply to 1TB SATA drive configurations, dual controllers under
federal pricing:
HP MD600 - $722/TB
DELL MD1000 - $680/TB (780/TB w/ nearline-SAS)
Sun J4500 - $1014/TB (federal discount is a mere 13%, not 40)
NexSan SATAbeast - $1400/TB (FC attached dual-head)
Of the "we force you to buy our overinflated drives" camp, Dell is the cheapest
but also the most inefficient by far on power/space. The HP puts 70 disks in
4U. NexSan 42, and Sun 48. The clear winner here is HP.
