About I/O performance tuning
53xx has up to 12 file systems. In general, the best I/O performance can be achieved if I/O requests are well balanced across the 12 file systems. NetBackup provides the following three load balancing algorithms that you can choose from:
0 ---- disable load balance
1 ---- default load balance(by capacity and throughput)
2 ---- load balance by number of source ID
Default is 1 (load balance by capacity and throughput). The tuning parameter is set in contentrouter.cfg file under the directory /msdp/data/dp1/pdvol/etc/puredisk. You can experiment with the other algorithms and find the best for your environment.
