:Suppose you have bunch of currently available 160G disks. AFAICC we *can*

:these into two 560G (thus allowed) RAID5 vinum. Or did I miss something?

You can certainly create a RAID system that exceeds 1TB in physical
disk storage, just as long as the *logical* storage does not exceed
1TB.
So, for example, you could 2TB worth of disks to create a 1TB logical
disk.
Or, for example, you could take 12 160G disks, split each one into
two 80G partitions (say 'd' and 'e'), and the RAID-5 all the 'd'
partitions together into a 800G logical drive and RAID-5 all the
'e' partitions together into another 800G logical drive.
