Best performance is achieved when multiple RAID sets are configured and optimized under a pair of
adapters in a high availability, multi-initiator RAID configuration (dual storage IOA) which allows for an
Active-Active mode of operation.
The adapter support a maximum of 98 attached disk devices that depends on the drive enclosure
attached. A maximum of 48 devices can be solid-state devices (SSDs). Externally attached devices are
designed to run at a maximum data rate of 6 Gbps for SAS disk devices and 3 Gbps for SAS tape
devices. This adapter supports RAID and non-RAID DASD, and SAS tape devices. Specific device
attachment support rules apply. This adapter supports the multi-initiator and high availability (dual
storage IOA) configurations in AIX, IBM i, and Linux partitions. This adapter enables configuring the
SAS drives as dedicated hot-spares with equal or higher capacity.
Important: For more information, see the SAS RAID controllers for AIX, SAS RAID controllers for IBM i,
or SAS RAID controllers for Linux topics for more information and important considerations for
multi-initiator and high availability or dual storage IOA configurations.
Figure 49 shows the adapter. The connector plug (A) is installed in an empty port and prevents damage
to that port whenever a cable for the adjacent port connectors is plugged-in or removed.
