Hi, I have inherited 2 TSM instances which offsite to each other using virtual volumes using a
dedicated 1 Gigabit ethernet link. The device classes all have a capacity of 20,480.0.
Server A copies poola to poolremotea and Server B copies poolb to poolremoteb.
A. the copies are slow and sometimes very slow.
b. filesize copied is from aprrox 100 mb to 250gig
c. simultaneous cross copying - depending on when various housekeeping runs.
d. various pools cross copied - varying sizes daily
e. used for both DB snapshot and copy pools
I am planning to ask for more tape drives on ServerB(money permitting) to take at least half
the traffic off the above method - so only one side vaults to the other using virtual volumes.
Does anyone have any tips on how to speed this up? Network tell me the link is only
50-70% utilised.
thanks rob
