SAS Multipathing

You can use J4200/J4400 arrays in a serial-attached SCSI (SAS) multipathing
configuration. Multipathing provides higher availability by allowing data to use
multiple paths to the arrays from Host Bus Adaptors (HBAs) on the same server or
on different servers.
Multipathing capability resides in the operating systems running on the servers, not
on the J4200/J4400 arrays. You enable, disable, and configure multipathing through
the operating software.
