PCIe3 4 x8 SAS Port Adapter (FC EJ10; CCIN 57B4)
Learn about the specifications and operating system requirements for the feature code (FC) EJ10 adapter.
Overview
The PCIe3 4 x8 SAS Port 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 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 40 on page 90 shows the PCIe3 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 40 on page 90 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.
