We were running tsm 4.2.2.4 on an S7A AIX server. We were putting through approx 1.7 TB nightly with approx 85% going to disk storagepool and the remaining going direct to tape. We were also testing Lan-free with Gresham EDT-Distributape and STK acsls/9840 tape drives and we were consistently on an UDB api backup receiving 15 MB/s
one month ago we upgraded all server and storageagents to tsm 5.1.1.6 level and since then we have seen performance drop. We are having trouble getting through the 1.7 TB nightly. The same lan-free tests are only getting us around 10 MB/s. We will be upgrading to a bigger and more powerful aix server this weekend in hopes that the performance drop is related to our S7a server reaching the end of its life span but I know when we upgraded from tsm 3.7 to 4.2 we saw an increase in server performance, I'm worried that the upgrade from 4.2 to 5.1 has gone in reverse. Has anybody sees anything remotely similar after an upgrade to tsm 5.1.1.6 ??? thanks Robert Burton Enterprise Storage Network Analyst Royal Bank of Canada 315 Front St West Toronto, On, M5V 3A4 * 416-348-3849 * [EMAIL PROTECTED] <mailto:Robert.Burton@;rbc.com> ------------------------------------------------------------ This e-mail may be privileged and/or confidential, and the sender does not waive any related rights and obligations.
