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 1 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: See the
SAS
RAID controllers for Linux topic for
more information and important considerations for multi-initiator
and high availability or dual storage IOA configurations
Figure 1 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.

Specifications
- Item
- Description
- Adapter FRU number
- 00E7167 (Designed to comply with RoHS requirement)
- Connector plug part number
- 00FW784 (The connector plug 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.)
- I/O bus architecture
- PCIe 3.0 but compatible to PCIe 2.0 or PCIe 1.0 slots.
- Slot requirement
- One available PCIe x8 slot per adapter.
- Cables
- Specific AE1 or YE1 SAS cable features with new narrow HD connectors
are used to attach the adapter to SAS devices.
- SAS device attachment requires specific cables
that are provided with the subsystem or device features that are being
attached.See Serial
attached SCSI cable planning.
- Voltage
- 3.3 V
- Form factor
- Short, low-profile but packaged for full-height installations.
- Maximum number
- For the maximum adapters supported, see the PCI adapter placement
topic collection for your system.
- Attributes
- Four external mini SAS HD 4x connectors provide attachment of
SAS devices
- SAS Serial SCSI Protocol (SSP) and Serial Management Protocol
(SMP)
- Concurrent firmware update
- Removable media device (DVD and SAS tape) are supported in a single
controller configuration only and cannot be combined with disk devices
attached to the same adapter. Removable media is not supported in
multi-initiator and high availability (dual storage IOA) configurations
- Support for multi-initiator and high availability or single controller
configurations
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 there are any prerequisites for this feature and attaching
devices. To check for the prerequisites, see IBM® Prerequisite
website .
The adapter is supported on the following
versions of the operating system:
- Supported on Firmware level 7.8, or later.
