I recently worked with a customer in a similar environment:

STK Powderhorn, ACSLS on Solaris, TSM on Windows 2000, 9840 fiber attached
drives.

This is a killer system.  The disk pool is 500 GB of SAN attached RAID5
disk.  We're able to move over 100 GB/hour to 10 drives.  We're hammering
the same storage pretty hard: both migration and backup stg occurring
simultaneously.  If we could run one or the other to all 10 drives we could
probably see even higher throughput.

The ACSLS portion of this works very well.  We've had to "learn" how it
wants to work with checkin and checkout of volumes but that didn't take
long.  TSM shares the library with STK CAM.  Except for one fumble fingered
incident, no problem sharing the library.
