What is the throughput you are achieving? Mt experience is that it is
very difficult to keep an LTO drive streaming. Drive compression has a
large effect. With drive compression, you will need a total system which
can maintain 15 MB/sec X Compression Ratio. In addition, the TSM overhead
per file can slow down even the fastest systems. Look in the archive for
some test numbers I posted for a system very much like yours. I posted it
about a month ago.

Subject: LTO 3584 in a SAN not use several drives in a session
Hi all...
I have the following, AIX 4.3.3 TSM Server 4.2.0 TSM Storage Agent 4.2.0
TSM Client 4.2.0 TDP for R3 3.2.0.6, LTO 3584 with 4 drives. The SAN
fabric is with McData Directors ED-5000 and the LTO is connected to a
McData ES-1000, and this conected to the director.
I can configure without problems the library and drives in the AIX and
TSM, but I can4t use several drives in a backup session. I set
Resourceutilization in 8, MaxNumMntPoint in 2 to use two drives, the
StorageAgent opens several sessions but only mount a drive.
Thanks in Advance
