This topic describes the device drivers that are supported by the storage subsystems in the SAN infrastructure.
For the clients, SAN File System requires either a single-pathing or a multi-pathing device driver to communicate with the storage subsystems.
A single-pathing device driver allows for basic communication between the client machine and a storage subsystem. You can use any standard single-pathing device drivers that are supported by your storage subsystems.
A multi-pathing device driver allows multiple Fibre Channel paths to be connected to the storage subsystem and to be managed for functions such as redundant-path failover and load balancing. The multi-pathing device drivers you need on the clients depends on the types of storage subsystems you have in the SAN environment:
