probably be slowed until the controller pairing is established again. This ultra-dense SSD
option is similar to the Ultra Drawer (FC 5888), which remains available to B and C-models of
the Power 720, and Power 740.
Figure 2-31 shows the picture of the EXP30 drawer.

Each controller is connected to a GX++ 2-port PCIe2 x8 adapter (FC EJ03 CCIN 2C1E) in a
Power 720 and Power 740 server through a PCIe x8 cable. Usually both controllers are
attached to one server, but each controller can be assigned to a separate server, or a logical
partition.
Table 2-27 lists the RAID levels for the AIX, IBM i, Linux operating system, which are
supported by the controller.
Table 2-27 Supported RAID levels
The EXP30 Ultra SSD I/O drawer (FC EDR1) delivers up to 480,000 IOPS (read only), up to
410,000 IOPS (60% read and 40% write), or up to 325,000 IOPS (100% write) and has up to
30% performance improvement over the previous version of the EXP30 (FC 5888).
Reminder: The previous EXP30 drawer (FC 5888) is not supported on the D-models of
the Power 720 and Power 740 servers.
