Multipath HA requirement
Multipath HA is required on all
Multipath HA was previously referred to as
except for some HA pairs system configurations, which use single-path HA and lack the redundant standby connections. FAS22xx Multipath Storage.
What multipath HA for HA pairs is
Multipath HA provides redundancy for the path from each controller to every disk shelf in the configuration. It is the preferred method for cabling a storage system. An without multipath HA has only one path from each controller to every disk, but an HA pair with multipath HA has two paths from each controller to each disk, regardless of which node owns the disk.

How the connection types are used
A multipath HA configuration uses primary, redundant and standby connections to ensure continued service in the event of the failure of an individual connection.
Advantages of multipath HA
Multipath connections in an reduce single-points-of-failure. HA pair
