features must be installed on the same system and partition. The dual controllers support the Easy Tier
®
function that enables the controllers to automatically move hot data to attached SSDs and cold data to
attached HDDs in the AIX or Linux systems.
Important: 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
Specifications
Item
Description
Adapter FRU number
00FX840 (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 downward compatible to 2.0 and 1.0
Slot requirement
One PCIe x8 slot per adapter.
Adapters are installed in pairs.
For higher availability, place adapters in separate enclosures where supported.
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, full-height
Cables
Specific X , YO, or AA SAS cable features with new narrow HD connectors are used to attach to the
other adapter or expansion drawers.
Special cabling is required for multi-initiator and high availability configurations. For more
information, see Serial attached SCSI cable planning.
Attributes provided
• Support of the SAS Serial SCSI Protocol (SSP) and Serial Management Protocol (SMP).
• Provides RAID 0, RAID 5, RAID 6, RAID 10, RAID 5T2, RAID 6T2, and RAID 10T2 with hot-spare
capability. System level mirroring through the operating system is also supported. JBOD
functionality (512 byte) is not supported except for the initial formatting to 528 bytes of new
devices, as required.
Important requirements for adapter installation
If you are attaching a new or existing FC 5887 to an FC EJ0L adapter, verify that the latest System
Enclosure Services (SES) code is applied to the FC 5887 before attaching to the FC EJ0L 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.
