SATP and PSP
PSP:
Path Selection Plug-In, also called Path Selection Policy.
Handles path selection for a given device.
SATP:
Storage Array Type Plug-In, also called Storage Array Type Policy.
Handles path failover for a given storage array
To manage storage multipathing, ESXi uses a collection of Storage APIs, also called the Pluggable Storage Architecture (PSA). The PSA is an open, modular framework that coordinates the simultaneous operation of multiple multipathing plug-ins (MPPs). The PSA allows 3rd party software developers to design their own load balancing techniques and failover mechanisms for particular storage array, and insert their code directly into the ESXi storage I/O path.
