Managing cluster performance for NDMP sessions
NDMP Redirector distributes NDMP loads automatically over nodes by using the optional 2x10GbE + 2x8GB Fibre Channel NIC on Generation 6 nodes. You can enable NDMP Redirector to automatically distribute NDMP two-way sessions to nodes with lesser loads. The load-distribution capability results in improved cluster performance when multiple NDMP operations are initiated.
NDMP Redirector checks for the following before redirecting the NDMP operation:
- CPU usage
- The number of running NDMP operations
- The availability of tape devices
