PCIe3 RAID SAS quad-port 6 Gb Adapter (FC EJ0J; CCIN 57B4)
Learn about the specifications and operating system requirements for the feature code (FC) EJ0J adapter.
The PCIe3 RAID SAS quad-port 6 Gb Adapter is a PCI Express (PCIe), generation 3, RAID SAS adapter
that has a low-profile, 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 configurations. SAS tape attachment is only supported
in a single adapter configuration and cannot be mixed with SAS disk on the same adapter. The adapter
does not have write cache. Figure 36 on page 81 shows the PCIe3 RAID SAS 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 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 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.Linux. 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.
