I read in a the Tivoli guide (A brief Introduction to IBM Tivoli Storage
Manager Architecture)
under Tape Drives  (best practices)

Where it say's Carefully consider card and bus throughput when attaching
tape
drives to systems most protocal/tape combinations can accommodate 2-3
tape,
drives per card? We would like to use more than say 10 12 or more
but not to cause issues.

We are Using 3590-H1A's (soon to upgraded to 3592's) which
would  could change the amout of tape drives we use.

We are using FC connections (the HBA's that are attached to the tape
drives are 1GB but are piped in at 2GB.

3590's Assumed speed  39 (GB/HR)
3592's  Assumed speed 112 (GB/HR)


Thanks for any replies!
