On the TSM-server you define the paths of system A, the storage-agent system. System B will then make will send the backup-data via the LAN to the storage-agent on system A. (as specified with "LANFREETCPServeraddress") >From system A the data will be sent over the SAN to a tapedrive.
This mechanism with a remote storage-agent is nice when you have a fast internal/virtual network, like in the IBM's P570's. You only need 1 system with an HBA to tape while the other lpars in the system use the internal network to sent the data to the system with the HBA. I played with it and got a reasonable performance on a P570, when using a virtual internal network with an high MTU size.

ENABLELANFREE yes COMMmethod TCPip LANFREETCPPort 1511 LANFREECOMMMETHOD TCPip LANFREETCPServeraddress sta_2.domain.hr TCPPort 1500 TCPServeraddress main_tsm.domain.hr ... now my question is : when i define /dev/rmt drives i must do it on STA server (A) which sees the drives phisicaly and hardlinked to /dev directory exactly as seen by the MAIN_TSM server OR can i place dummy /dev/rmt* on client server since it's using information from STA server which sees the drives (rmt's) for real ? how do you manage it ? i got a feeling after some implementation that STA must be installed and configured on every server which has BA client ready to backup/archove on it ... (this is maybe even true) it would be nice that 1 STA i enough and lanfree BA clients can use him ... i think i need a vacation, i talk too much thanks. my new record :-) ------------------------------------------------------- Total number of objects inspected: 253 Total number of objects backed up: 253 Total number of objects updated: 0 Total number of objects rebound: 0 Total number of objects deleted: 0 Total number of objects expired: 0 Total number of objects failed: 0 Total number of bytes transferred: 2.96 TB LanFree data bytes: 2.96 TB Data transfer time: 3,948.46 sec Network data transfer rate: 805,348.31 KB/sec Aggregate data transfer rate: 110,039.74 KB/sec Objects compressed by: 0% Elapsed processing time: 08:01:37 TSM 5.3.4 AIX 5.2 LTO3 bla bla ...
