• The green LED indicates link status. If the green LED is on, at least one PCIe link is in the trained state.
• The amber LED indicates FRU identify. If the amber LED is on, it will blink at 2 Hz, and indicates that the
adapter is in the identify function state.

Overview
The PCIe3 SAS RAID quad-port 6 Gb adapter is a PCI Express (PCIe), generation 3, SAS RAID adapter
that has a low-prole, short-form factor, but packaged for full height installation. The adapter is used in
high-performance and high-density, serial attached SCSI (SAS) applications. It supports the attachment
of SAS disk and SAS tape by using four mini SAS high-density (HD) x4 connectors that allow the physical
links to be used in various narrow and wide-port congurations. SAS tape attachment is only supported in
a single adapter conguration and cannot be mixed with SAS disk on the same adapter. The adapter does
not have write cache. Figure 44 on page 136
shows the PCIe3 SAS RAID quad-port 6 Gb adapter.
Important: There is no FCoE support on POWER9 systems.
The adapter is a 64 bit, 3.3 V, bootable SAS adapter that provides RAID 0, 5, 6, 10, 5T2, 6T2, and 10T2
capability, and system level mirroring via the operating system. The adapter provides both single and dual
RAID controller congurations. Dual controller congurations (dual storage IOA) must run RAID. JBOD
(512 byte) functionality is supported only in a single controller conguration based on the operating
system. Best performance is achieved when multiple RAID sets are congured and optimized under a pair
of adapters in a high availability, multi-initiator RAID conguration (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. Specic device attachment
support rules apply. This adapter supports the multi-initiator and high availability (dual storage IOA)
congurations in AIX, IBM i, and Linux partitions. This adapter enables conguring the SAS drives as
dedicated hot-spares with equal or higher capacity.
Important: 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 congurations
