Subject: NT client 4.2.1 - scheduled backups EXTREMELY low
transfer rate
I upgraded to TSM 4.1.4 server over the weekend, and upgraded the NT
clients from ADSM 3.1.0.8 to TSM 4.2.1.
My NT clients are now seeing aggregate data transfer rates of 200-400
KB/Sec. Previously they were getting 2-4 MB/Sec. The only thing that
changed on these clients is the ADSM to TSM client upgrade.
My AIX clients, running the ADSM 3.1.0.8 client, are not having a problem,
they are still achieving the 2-4 MB/Sec transfer rates.
Anyone else out there have similar problems? Any advice would be
appreciated. TSM support just says "it's a performance problem, call
Consult Line."
The TSM server is AIX 4.3.3, with 256M RAM, gigabit ethernet adapters.
The NT servers are all 100 Mbs ethernet, except two which are gigabit
adapters and still exhibit this problem.
Some of these backups are direct to tape, but had been before the upgrade.
The tape library is a Magstar 3575 and none of it's operations appear
degraded.
Thanks... Ken
