Multipathing Software Configuration
Configuring Native Multipathing
PowerStore supports the Native Multipathing Plugin (NMP).
This section describes the procedure required for configuring native multipathing for PowerStore volumes.
For best performance, it is recommended to do as follows:
•
Set the NMP Round Robin path selection policy on PowerStore volumes presented to the ESXi host.
