PCIe2 RAID SAS Adapter Dual-port 6-Gb LP (FC ESA2; CCIN 57C4)
Learn about the specifications and operating system requirements for the feature code (FC) ESA2
adapters.
Overview
The FC ESA1 is a full-height adapter and the FC ESA2 is a low-profile adapter. The names of these two
adapters are:
v FC ESA1: PCIe2 RAID SAS Adapter Dual-port 6-Gb
v FC ESA2: PCIe2 RAID SAS Adapter Dual-port 6-Gb LP
The PCI Express generation-2 (PCIe2), RAID SAS dual-port 6-Gb Adapter provides high-performance
solid-state drives (SSD) controller functions by using the PCIe2 technology. The adapter does not have
write cache and thus pairing with another PCIe2 RAID SAS Adapter Dual-port 6-Gb (either FC ESA1 or
FC ESA2) is optional. Pairing can provide controller redundancy and enhanced performance. There are
no batteries in the adapter to maintain.
The PCIe2 RAID SAS Dual-port 6-Gb Adapter supports SSD only. Hard disk drives (HDD) are not
supported by this adapter. The 69 GB SSD features are not supported.
The adapter provides two mini-SAS high-density (HD) connectors for the attachment of SSDs located in
the FC 5887 EXP24S, FC 5802, or FC 5803 12X PCIe I/O drawers. X , YO, or AT SAS cables with HD
connectors are used to attach to these drawers. A maximum of 18, 26, or 24 SSD can be controlled
depending on the I/O drawers being used. Only one drawer can be controlled. The FC 5802 12X PCIe
I/O drawer has a maximum of 18 SSDs. The FC 5803 PCIe I/O Drawer has a maximum of 26 SSDs. The
FC 5887 EXP24S Drawer has a maximum of 24 SSDs. If the SSDs are located in FC 5802 or FC 5803, one
or both of the controlling adapter pair must be located in that FC 5802 or FC 5803.
A single adapter or a pair of adapters provides RAID 0, RAID 5, RAID 6, and RAID 10 configurations for
systems or partitions running the AIX or Linux operating system and VIOS. The PCIe2 RAID SAS
Dual-port 6-Gb adapters do not support JBOD. The adapter provides RAID 5 and RAID 6 for systems or
partitions running the IBM i operating system. IBM i provides both mirroring and data spreading.
Systems or partitions running the AIX or Linux operating system and VIOS provide mirroring (logical
volume manager (LVM)).
For details about slot priorities and placement rules, see the PCI adapter placement topic collection for
your system.
