Does IBM have a storage solution with the following attributes?

1) Can store at least 30 terabytes, with a single, unified namespace

2) Costs between $50k and $200k

3) Doesn't have to be blazing fast. In fact, a tape jukebox or HSM might
be acceptable, though so far we've only discussed RAID systems.

Does this solution support 251G SATA drives by any chance? We have a lot
of them from something else.

Thanks!
