Malkit,
Try setting, in dsmserv.opt, DISKMAP NO. This setting can improve
performance with larger disk pools and with some disk sub-systems. To get
the best disk storage pool performance on Sun, we recommend using the
raw-partitions (see the reference manual or the help on "define vol" and
the notes on the disk device class).
Thanks...Jim Riehl

Subject: Solaris Performance
Hello
We have Solaris ADSM server v3.1.2 , with the following options in
dsmserv.opt :
BUFPoolsize 20480
EXPInterval 24
MOVEBatchsize 1000
MOVESizethresh 500
TCPNodelay yes
TCPWindowsize 0
TXNGroupmax 256
USELARGEbuffer yes
USELARGETAPEBLOCK yes
The backup is done to disk stg pool. We get bad performance on backing
up and restore as well. Attach are two of the worst performance during
the night backup.
I will appreciate your experience on tunning the ADSM server and
clients. We get better performance when doing selective/incremental
backup directly from the client, but still it doesn't get to 1mb/sec.
Awful !
