Specifications
Item Description
Adapter FRU number
000MH910 (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
For more information about slot priorities, maximums, and placement rules, see PCIe adapter
placement rules and slot priorities (http://www.ibm.com/support/knowledgecenter/POWER9/
p9eab/p9eab_mtm_pciplacement.htm) and select the system that you are working on.
Voltage
3.3 V
Form factor
Short, low-profile but packaged for full-height installations.
Cables
Specific X, YO, AA, or AT SAS cable features with new narrow HD connectors are used to attach
to the other adapter or disk expansion drawers.
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. 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 Support for multi-initiator and high availability or single controller configurations
Important requirements for adapter installation
If you are attaching a new or existing 5887, ESLL, or ELLS enclosure to an FC EJ0M adapter, verify that
the latest System Enclosure Services (SES) code is applied to the enclosure before attaching to the FC
EJ0M adapter. For details, 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:
v The latest version of enabling libraries and utilities can be downloaded from Fix Central
(http://www.ibm.com/support/fixcentral/).
v IBM Power Systems Prerequisites (https://www14.software.ibm.com/support/customercare/iprt/
home).
v IBM SSIC (System Storage Interoperation Center)(http://www-03.ibm.com/systems/support/storage/
ssic/interoperability.wss).
