supports RAID and non-RAID DASD, tape, and optical devices. This adapter supports the multi-initiator
and high availability configurations in AIX and Linux. IBM i does not support feature 5901 in
multi-initiator and high availability configurations.
Important: See the SAS RAID controllers for AIX, SAS RAID controllers for Linux, or SAS RAID
controllers for IBM i topics for more information and important considerations for multi-initiator and
high availability or dual storage IOA configurations
The 5901 supports SAS SFF disk drives located in a PCIe 12X I/O Drawer or SAS disk drives located in
an EXP 12S Disk Drawer or SAS disk drives located in a supported POWER system unit (split disk
backplane).
