IBM 74Y4064 Handbook

SAS device attachment requires specific cables that are provided with the subsystem or device
features that are being attached. Special cabling is required for multi-initiator and high
availability configurations. Specific AE1 or YE1 SAS cable features are required for SAS Tape
attachment. See Serial attached SCSI cable planning.
Attributes
v Four external mini SAS HD 4x connectors provide attachment of SAS device enclosures
v SAS Serial SCSI Protocol (SSP) and Serial Management Protocol (SMP)
v RAID 0, 5, 6, or 10 with hot-spare capability. System level mirroring through the operating
system is also supported. JBOD functionality (512 byte) is supported in a single controller
configuration only.
v Concurrent firmware update
v Removable media device (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
v Support for multi-initiator and high availability or single controller configurations
Other important requirements for adapter installation
If you are attaching a new or existing FC 5887 to an FC EJ0J adapter, verify that the latest System
Enclosure Services (SES) code is applied to the FC 5887 before attaching to the FC EJ0J adapter, see the
IBM Prerequisites website.
An automatic sector conversion takes place for use with the new adapter when migrating existing SAS
disk enclosures and devices from existing previous PCIe SAS adapters to PCIe2 or PCIe3 SAS adapters.
For more information about the migration procedures, see Upgrading a SAS RAID storage adapter.
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 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
