Concurrent maintenance procedure
Concurrent maintenance of this double-wide adapter is not supported through the Hardware
Management Console (HMC). Concurrent maintenance must be done from within the partition operating
system. In IBM i, the Hardware Service Manager (HSM) of the system or owning partition automatically
turns off or turns on the power on both PCI slots when either slot is selected.In AIX or Linux , you must
manually power off and on each slot separately.
Important:
v You must turn off the power to both PCI slots if you are installing or removing this adapter with the
power to the system turned on.
v If this adapter is the load source IOA, or any other storage IOA with critical DASD attached for the
system, this concurrent maintenance procedure should be done by a qualified service provider.

Overview
The Peripheral Component Interconnect-X (PCI-X) DDR External Dual – x4 Port SAS Adapter is a
low-profile adapter for high-performance and high-density, serial-attached SCSI (SAS) applications. The
adapter provides two mini SAS 4x connectors, which allow the eight physical links to be used in various
narrow and wide-port configurations. The adapter is a 64-bit, 3.3 V, bootable SAS adapter that provides
RAID 0, 5, 6, and 10 capability. Some RAID level support is operating system dependent. The adapter
provides RAID 0, RAID 5, RAID 6 and RAID 10 for AIX and Linux. Under the IBM i operating system,
mirroring and data spreading is provided by the operating system and RAID 5 and RAID 6 is provided
by the adapter.
The adapter does not have write cache. (The write performance of RAID level 5 and RAID level 6 may be
poor on adapters which do not provide write cache. Consider using an adapter which provides write
cache when using RAID level 5 or RAID level 6.)
The adapter can address up to 48 SAS disk drives, although the actual number of drives in a system is
subject to the physical placement limitations of the system. Externally attached devices are designed to
run at a data rate of 1.5 Gb/s for Serial Advanced Technology Attachment (SATA) devices, and 3 Gb/s
for SAS devices. This card supports RAID and non-RAID DASD, tape, and optical devices. Feature 5912
supports the 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
