Hi Guru's I have recently installed a new TSM 4.1.3 server on a P600 and AIX 4.1.3. I have 2*75Gybyte RAID5 Disk Cache attached through SSA. The performance for reading from disk to tape is fine for small files, but I only get 2.5MB/Sec when files are larger than say 1Gbyte. I have set "SELFTUNETXNsize Yes", and it brought it up tothis speed when using two drives.
I have 18 *4Gbyte files on each RAID5 and can see that the data is evenly distributed in each file. I can see that the file say 7Gbytes is spread throughout many of the Disk Storage Volumes. I don't want to go straight to tape as this causes a huge headache in scheduling. Is this a known bottleneck or is there a way around to get at least 20MB/Sec?
