Hi *,
I use on both server logical volumes and jfs-filesystems. All (DB, log and
disk pool) are on jfs-filesystems.
Is it better when I change to RAW devices?
Best regards,
Frank Mueller

Are you using RAW volumes or logical, file system mounted
volumes for DB, log, and disk pool? RAW volumes make a HUGE difference.
You should also have your client's NIC's forced to 100/Full (the ones
using fastethernet), don't let them auto negotiate, kill's backup
performance.

Subject: TSM performance and network options
Hi *,
our TSM environment is very slow (backup from the clients and the backup
storage pool from the first to the second server). So I would like to
describe our environment once roughly: We have 2 TSM server (Version
5.1.8) which runs both on AIX boxes with AIX 5.1. On the first server is
an 3494 library (with 4 3590 drives) connected and on the second server
an 3583 (with 3 LTO Ultrium1 drives).
The clients (AIX-clients and Windows clients) are connected over
fastethernet or gigaethernet. First TSM server has both adapter (fast
and giga). The connection between the first and the second TSM server is
gigaethernet.
Can you give me some tips to increase the performance? I think that are
some TSM and AIX options (TCPWindowsize etc on TSM side and son
no-Paramter on AIX site).
What is a good start for this options?
Best regards,
Frank Mueller
