Introduce MSDP load balancing servers gradually
Veritas recommends that you add load balancing servers only after the storage server reaches maximum CPU utilization. Then, introduce load balancing servers one at a time. It may be easier to evaluate how your environment handles traffic and easier to troubleshoot any problems with fewer hosts added for deduplication.
Many factors affect deduplication server performance.
Because of the various factors, Veritas recommends that you maintain realistic expectations about using multiple servers for deduplication. If you add one media server as a load balancing server, overall throughput should be faster. However, adding one load balancing server may not double the overall throughput rate, adding two load balancing servers may not triple the throughput rate, and so on.
If all of the following apply to your MSDP environment, your environment may be a good candidate for load balancing servers:
The deduplication storage server is CPU limited on any core.
Memory resources are available on the storage server.
Network bandwidth is available on the storage server.
Back-end I/O bandwidth to the deduplication pool is available.
Other NetBackup media servers have CPU available for deduplication.
Gigabit Ethernet should provide sufficient performance in many environments. If your performance objective is the fastest throughput possible with load balancing servers, you should consider 10 Gigabit Ethernet.
