Dear Geek,

VMware ESXi has its own multipathing software Native Multipath Module (NMP), which is available without the need for extra configurations.

NMP is the default multipathing module of VMware. This module provides two submodules to implement failover and load balancing.

SATP: monitors path availability, reports path status to NMP, and implements failover.
PSP: selects optimal I/O paths.

PSA is compatible with the following third-party multipathing plugins:

Third-party SATP: Storage vendors can use the VMware API to customize SATPs for their storage features and optimize VMware path selection.
Third-party PSP: Storage vendors or third-party software vendors can use the VMware API to develop more sophisticated I/O load balancing algorithms and achieve larger throughput from multiple paths.

Thanks.
