TSM Reclamation and large tape formats
2005-06-09 15:48:40
We are being pushed to improve our reclamation thresholds in order to drive
down the amount of tape volsers required...
We are using STK 9940 tape drives and get 300GB - 1 TB of data stored on each
tape. I'm trying to explain that with the larger tape sizes it is much more
difficult to keep the reclamation numbers at the same target levels as with the
smaller tape volumes.
We have 2 tsm servers / 50 lan-free clients / approx 2 TB of disk pool and we
backup 8 TB nightly...
Between copypool and migration we have limited reclamation cycles...
Just inquiring on what the rest of the tsm community is experiencing in regards
to tsm reclamation with large tape...
thanks
