There is very little information in this post to really tell what
might be happening here. The first suggestion, however, I would make is to
upgrade the TSM server and storage agent to a level of 5.2.2 or higher. The
reason for this is that there were numerous performance improvements made
in the 5.2.2 release with respect to communications between the TSM server
and the SAN Storage Agent. Also, there have been many improvements in the
area of tape handling in the 5.2.2 release that might address performance
problems.
I would not guarantee that this will fix the performance problems
you're having, but it should help. Also, at the higher release we (IBM)
have access to an improved server instrumentation trace that can help us
diagnose performance problems easier. If this does not completely address
the performance problem, I would suggest a call to TSM support and ask for
TSM performance assistance.

Hi all,
we have a lanfree under SAN network for a server TSM 5.1 AIX and a client
AIX .
the result of an archive of the node is as follow:
Total number of objects inspected: 9.820
Total number of objects archived: 9.820
Total number of objects updated: 0
Total number of objects rebound: 0
Total number of objects deleted: 0
Total number of objects expired: 0
Total number of objects failed: 0
Total number of bytes transferred: 44,86 GB
LanFree data bytes: 44,86 GB
Data transfer time: 352,82 sec
Network data transfer rate: 133.343,46 KB/sec
Aggregate data transfer rate: 2.621,99 KB/sec
Objects compressed by: 0%
Elapsed processing time: 04:59:03
as you can see, the performance of this archive is not good.
the network data tranfer rate is good (133.343,46 KB/sec), but Aggregate
data transfer rate: 2.621,99 KB/sec is not good.
what are the reason of such performance?
