Tape performance
2003-07-22 13:04:11
I am wondering if there is something in TSM that throttles the tape
performance we should be getting. I can do a dd test from the operating
system to the tape drive and with that receive 2 GB per minute (32 MB/sec)
but when I do a test through TSM, I only get 1 GB per minute.
My environment is:
TSM 5.7.0 on Solaris 8
Server: Sunfire 880
Tape drives are 9840 Fibre attached.
As a result, we are questioning the value of putting in the more expensive
tape drives when we can't seem to pump the data through as expected.
Any ideas of what I might look at would be appreciated.
Thanks,
