Disks
The 387 GB SSD (FC ES02 and FC ES04) used in the EXP30 Ultra SSD I/O drawer uses
high-performance, industrial-strength eMLC technology. These SSDs are packaged as
1.8-inch SAS drives, which can be added to or removed concurrently while the drawer is in
use.
A minimum of six SSDs are required in each Ultra drawer. Each controller can access all 30
SSD bays. The bays can be configured as one set of bays that is run by a pair of controllers
working together. Alternatively the bays can be divided into two logical sets, where each of
the two controllers owns one of the logical sets. With proper software if one of the controller
fails, the other controller can run both sets of bays.
FC ES02 and FC ES04 are identical SSD drives, but have separate feature codes for use with
the AIX, IBM i, and Linux operating systems. FC ES02 is used for AIX and Linux; FC ES04 is
used for IBM i.
EXP30 connection to a Power Systems server
The GX++ 2-port PCIe2 x8 adapter (FC EJ03 CCIN 2C1E) enables the attachment of the
EXP30 Ultra SSD I/O Drawer. The adapter is plugged into a GX++ slot of the 4U Power 720
and Power 740. Up to one PCIe cable connect the drawer to the GX++ 2-port PCIe2 x8
adapter.
The following cable lengths are available to connect a drawer with a GX++ 2-port PCIe2 x8
adapter.
