Hi TSM-ers , TSM server: 4.2.2.8 on IBM H50 with AIX 5.1 ML2, 1GB Memory, GigaBit Ethernet, 3494 libary with 2x 3590 drives TSM Client: Windows 2000, TSM 5.1.5, 1.5GB Memory, Disks on IBM ESS
I backup big Outlook .PST Files directly to tape. When TSM starts to backup big files (>300MB) I see on the AIX server with topas a throughput of up to 24M (readch/writech). But in the middle of the file it drops to as low as 3000K. CPU utilisation drops from 60% to 15%. No Wait at any time. I'm not very familiar with performance on AIX because our TSM server was bought as a black box (kind of). Has anyone seen this before? Thanks in advance! Thomas Rupp
