We in the process of moving to an IBM 3580 external LTO drive for manual offsite vaulting of primary storage pools. I have read several older reports on http://msgs.adsm.org about poor performance with TSM, LTO and small files. We are experiencing the same behavior and I was just curious if anybody has ran into this lately. We see about 10-15GB/hour with small files and 42-57GB/hour on larger files.
We are running TSM 5.1.6.5 on Win2k SP3. The drive is an external IBM 3580 and is the only device hooked to an Adaptec 2940 SCSI controller. We are also running v5.0.5.4 of the IBM 3580 drivers. I maxed out the following server options (which helped): MoveBatchSize 1000 TxnGroupMax 256 I also set the drive parameters via ntutil as described in this Redbook (which also helped): http://www.redbooks.ibm.com/redpieces/pdfs/sg246268.pdf Anybody else ran into these problems? Thanks, Colby
