For a migration project we have to transfer archive data from the old outdated TSM server to a new one.
The old server is running on AIX 7.1 with TSM 6.2.3.100, using 3592-4 drives.
The new server is running on Redhat 7.4 with Spectrum Protect 8.1.2 and a large disk subsystem as data storage.
The network between both servers allows a SCP file copy with about 50 Mb/s, but the TSM export to server runs with about 8 Mb/s only. This speed occurs after the database part of the export and after the mount of the tapes. So it is the current speed from 3592 tape through AIX, network and RedHat to the disk subsystem. All parts have been checked individually. The bottleneck must be between the 2 TSM servers. With this speed it would take more than half a year to transfer all data.
Any hints about tuning the transfer to at least the network speed ?
Regards
Uwe Koch
