We moved our 120Gb disk backup pool from a SSA D40 drawer (RAID5) to the
Shark and got an order of magnitude improvement in backup times.  40Gb
NOTES backups went from 20 hours to 4 hours.  The shark outperforms the
SSA disk by a significant amount.  If you start having performance
problems then I'd recommend moving all your TSM data to the shark and
using the SSA somewhere else. (That's what we're doing now)

We have 83 nodes (mixed AIX, Solaris, NT and FreeBSD) and the ADSM server
is a H70.
