Environment: TSM server AIX 5.3 P570 TSM 5.3.3.0 Client Win2003 HP Proliant DL585 64GB TSM client 5.3.2.2
We restored 178 GB in 7.5 hours. The restore consisted of 1 file that is 160 GB and 25 files totaling 18 GB. The 160 GB file was on 1 LTO3 tape in a L700 library with a 2 GB fibre connection. The restore initially started running at over 30 GB per hour and gradually slowed to less than 20 GB per hour by the time it completed for the large file. Then the 25 smaller files (18 GB) restored at the faster speed. The workload was light on the TSM server and the client. Can anyone provide some insight as to what may cause a large restore to decrease in throughput?
