I/O bus architecture
PCIe 3.0 but compatible to PCIe 2.0 or PCIe 1.0 slots.
Slot requirement
For details 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 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.
Internal SAS device attachment on a 9040-MR9 system requires specific AZ 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. For more information, see Serial attached SCSI cable
planning.
Attributes
• Four external mini SAS HD 4x connectors provide attachment of SAS device enclosures
• SAS Serial SCSI Protocol (SSP) and Serial Management Protocol (SMP)
• 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.
• Concurrent firmware update
• 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
• 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
Power Systems 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 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. For information about operating system and partition requirements, see one of the following
topics:
• The latest version of enabling libraries and utilities can be downloaded from Fix Central (http://
www.ibm.com/support/fixcentral/).
• Power Systems Prerequisites (http://www14.software.ibm.com/support/customercare/iprt/home).
• IBM SSIC (System Storage Interoperation Center) (http://www-03.ibm.com/systems/support/storage/
ssic/interoperability.wss).
• The latest version of the device driver or IBM Power RAID adapter utilities (iprutils) can be downloaded
from the IBM Service and Productivity Tools website (http://www14.software.ibm.com/webapp/
set2/sas/f/lopdiags/home.html).
