We have 2 NW 6.5 servers (1 sp8 and one sp7 soon to be upgraded), Dell PE 2650s with 4 GB ram and a little over 1 TB of data on a fiber san. I'm just starting to use Arcserve 11.5 for Linux, installed on SLES 10.2 on a dell 1950, 4 GB ram. No groupwise. The 2 NW servers are clustered, but I'm backing up the nodes directly, so no cluster awareness for the backups. I have GB connections to the backup agents.

Can anyone make any general recommendations to get the best throughput? I'm getting about 550 MB/minute in testing, but am hoping for better if I can get it.

Here's my current tsa.cfg file:

#######
Read Buffer Size:
65536
Read Threads Per Job:
4
Read Thread Allocation:
100
Read Ahead Throttle:
2
Cache Memory Threshold:
10
Disable Cluster:
yes
Show Cluster Volumes On Node:
no
Enable GroupWise:
0
Enable Caching:
yes
Disable Demigration:
no

I also have settings for tcp minshall, delayed ack and nagle all set to on.
Any suggestions are greatly appreciated. If I need to provide more info, I'll be glad to. Thanks for any tips.
