Operating system or partition requirements
If you are installing a new feature, ensure that you have the software that is required to support the new
feature and that you determine whether any prerequisites must be met for this feature and attaching
devices. To check for operating system and partition requirements, see one of the following links:

PCIe3 LP 4 x8 SAS Port Adapter (FC EJ11; CCIN 57B4)
Learn about the specifications and operating system requirements for the feature code (FC) EJ11 adapter.
The PCIe3 LP 4 x8 SAS Port Adapter is a PCI Express (PCIe), generation 3, RAID SAS adapter is a
low-profile, short-form factor adapter. The adapter is used in high-performance and high-density, serial
attached SCSI (SAS) applications. It supports the attachment of SAS DVD or 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 41 on
page 92 shows the PCIe3 LP 4 x8 SAS Port Adapter.
A maximum of four DVD or tape drives can be attached per adapter by using four AE1 cables (FC
ECBY). A maximum of eight DVD or tape drives can be attached by using four YE1 cables (ECBZ).
Externally attached devices are designed to run at a maximum data rate of 6 Gbps for SAS tape devices.
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 41 on page 92 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
