Redundant Controller SAS Port: (for Yotta 3 Single_Redundant Series)
Four 4-port SAS ports can be applied to the RAID subsystem. The RAID subsystem
supports Port 0, 1, 2, 3 and 0&1&2&3 cluster option.
LUN base: Each SAS device attached to the SAS host adapter must be assigned a
unique SAS ID number. A SAS RAID controller can connect up to 122 devices and
128 (16*8) volumes. The RAID subsystem is as a large SAS device. We should
assign an LUN base from a list of SAS LUNs.
