    Multipathing
    Multipathing allows an ESX or ESXi host to use more than one physical path between the ESX or ESXi host and the
    storage array.
    Multipathing provides load balancing, which is the process of distributing I/O across multiple physical paths, reduces or
    removing potential bottlenecks.
    Multipathing also provides redundancy and fault tolerance in case of a failure of any element in the SAN network such as
    an adapter, switch, or cable. The ESX or ESXi host can switch to another physical path, which does not use the failed
    component. This process of path switching to avoid failed components is known as path failover.
    To support path switching with an FC SAN, the ESXi host typically has two or more HBAs available from which the storage
    array can be reached and for full fault tolerance uses two or more switches. Additionally for full fault tolerance two storage
    processors on the Hitachi storage arrays should be utilized so that the HBA can use a different path to reach the disk
    array.
