Hi All,
Environment:
- TSM v3.7.3
- IBM7337 library (15 slots) with around 10 tapes for onsite tape pool
status full, a cleaning tape and 3 to 4 scratch tapes
- Currently there are around 40 nodes defined in TSM
- a few more nodes are coming and backup data volume on existing nodes is
expected to grow, so there will be move media operation soon
- there is only one onsite tape storage pool defined and that is having
collocation off
To improve restore performance, I am thinking of turning on collocation for
onsite tape pool. But there are more nodes than number
of slot in library, should I define maxscratch=N and let TSM to collocate
data on the 40 nodes within the N tapes. Keep monitoring tape usage and
adjust N whenever necessary. Any suggestion on the setup and the number N?
Thanks in advance.
Regards,
Eric Tang
