EDR1 PCIe storage enclosure PCIe2 (3.1 GB Cache RAID SAS
Enclosure 6 Gb x8)
v This enclosure is a 1-unit (1U) high
I/O drawer that provides 30
hot-swap SSD bays and a pair of
integrated SAS controllers. The
SAS controllers provide large write
cache and enhanced performance.
v
The EXP30 does not support
HDDs.
v
A maximum of 30 SSDs are
supported in this disk drive
enclosure.
v
The EXP30 can be configured as
follows:
– One set of 30 bays and the set is
owned by both controllers that
are working together.
– Two logical sets and each of the
two controllers owns one of the
logical sets.
v
The EXP30 is attached to the

Installing a disk drive or solid-state drive in the 8248-L4T, 8408-E8D, or
9109-RMD with the AIX system or logical partition power turned on
Learn how to install a disk drive or solid-state drive in a system, drive enclosure, or an expansion unit,
with the AIX
®
operating system or logical partition that controls the drive location is powered on.
If you are servicing a failing part, see the service procedures for “Replacing a disk drive or solid-state
drive in the 8248-L4T, 8408-E8D, or 9109-RMD with the AIX system or logical partition power turned on”
on page 55.
Continue with this procedure for installing a new or upgraded drive.
Before installing or replacing a feature, ensure that the software required to support the feature is
installed on the system. For information about software prerequisites, see IBM Prerequisite website
(www-912.ibm.com/e_dir/eServerPrereq.nsf). If the required software is not installed, go to Fix Central
(www.ibm.com/support/fixcentral) to download it, and install it before continuing.
If you are installing solid-state drives, review the configuration rules and then return here. For more
information, see “Solid-state drive configuration rules for the 8248-L4T, 8408-E8D, or 9109-RMD” on page
