Table 1-15 Maximum number of disk-only I/O drawers supported
1.6.4 EXP30 Ultra SSD I/O Drawer
The enhanced EXP30 Ultra SSD I/O Drawer (FC EDR1) provides the Power 720 and
Power 740 up to 30 solid-state drives (SSD) in only 1U of rack space without any PCIe slots.
The drawer provides up to 480,000 IOPS and up to 11.6 TB of capacity for AIX or Linux
clients. Plus up to 48 additional hard disk drives (HDDs) can be directly attached to the Ultra
Drawer (still without using any PCIe slots) providing up to 43.2 TB additional capacity in only
4U additional rack space for AIX clients. This ultra-dense SSD option is similar to the Ultra
Drawer (FC 5888), which remains available to B and C models of Power 720, and Power 740.
The EXP30 attaches to the Power 720 or Power 740 server with a GX++ adapter, FC EJ03.

twenty-four 2.5-inch hot-swap SFF SAS HDDs on POWER6, POWER7, and
servers in 2U of 19-inch rack space. The EXP24S bays are controlled by SAS
adapters/controllers attached to the I/O drawer by SAS X or Y cables.
