TSM Performance with 3584 LTO-2 Drives
2005-10-20 12:22:42
Hi,
We're recently connected a 3584 with one L52 frame containing 2 LTO-2
fiber attached drives to our AIX server. We'll be using FAStT SATA
disk as a primary storage pool and migrating from disk to tape. Can
anyone with a similar setup provide any statistics on how this works
in the real world, i.e. MB/sec or GB/hour from disk to tape.
A test migration of 259 GB (152422 files) took 10.5 hours to
complete. This seems like abysmally slow performance, or is it
reasonable with a large numbers of small files?
TSM version: 5.3.1
MoveBatchSize 500
MoveSizeThresh 512
AIX version: 5.1
