We tested a TSM environment on both RAID5 and JBOD. Raid 5 performance for diskpool/database and/or log was far worse than the JBOD config. At the moment we are moving our big clients off the NSM (RAID5) to the WINtel JBOD. Just because of the RAID performance.
-----Oorspronkelijk bericht----- Van: Farren Minns [mailto:[EMAIL PROTECTED] Verzonden: donderdag 6 maart 2003 16:49 Aan: [EMAIL PROTECTED] Onderwerp: TSM Performance - Is it my backuppool OK, I have just done another test and here are my findings. TSM 4.2.2.12 running on a Solaris E250, 400Mhz, 1GB, 50GB backuppool on RAID5 array, 8500MB DB and LOG on separate internal disks (TSM mirrored). I just backed up a 100Mb file via a client on the same machine as the server. Data transfer rate 1.5MB/s. Terrible. File was on the same RAID 5 array as the backuppool. I then restored that very same file to the very same location and got a transfer speed of no less than 51MB/s. Much better! So, could the problem lie with my backuppool for some reason, and if so, how would I know. We do have caching turned on if that makes any difference. Any ideas on this one?
