PCIe3 RAID SAS quad-port 6 Gb LP Adapter (FC EJ0M; CCIN 57B4)
Learn about the specifications and operating system requirements for the feature code (FC) EJ0M adapter.
Overview
The PCIe3 RAID SAS quad-port 6 Gb LP Adapter is a PCI Express (PCIe), generation 3, RAID SAS
adapter that has a low-profile and short-form factor. The adapter is used in high-performance and
high-density, serial attached SCSI (SAS) applications. It supports the attachment of SAS hard disk drives
(HDDs) and solid-state devices (SSDs) by using four mini SAS high-density (HD) x4 connectors that
allow the physical links to be used in various narrow and wide-port configurations. The adapter does not
have write cache. Figure 25 on page 71 shows the PCIe3 RAID SAS quad-port 6 Gb LP Adapter.
The adapter is a 64 bit, 3.3 V, bootable SAS adapter that provides RAID 0, 5, 6, and 10 capability, and
system level mirroring via the operating system. The adapter provides both single and dual RAID
controller configurations. Dual controller configurations (dual storage IOA) must run RAID. JBOD (512
byte) functionality is supported only in a single controller configuration based on the operating system.
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 supports a maximum of 96 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. This adapter supports RAID
and non-RAID DASD. 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: 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
Figure 25 on page 71 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.
