The IBM TotalStorage DS4000 EXP100 Storage Expansion Enclosure is designed
for data archival, data reference, and near-line storage applications and enables the
attachment of Serial Advanced Technology Attachment (SATA) disk drives for
DS4000 storage subsystems such as the DS4100, DS4300, DS4400, DS4500, and
DS4800.

The EXP100 is a rack-mountable storage expansion enclosure that supports up to
fourteen 1.5 Gbps 400 GB SATA disk drive modules, offering up to 5.6 terabytes
(TB) of capacity per expansion enclosure.
Note: There are two EXP100 machine types:
v 1710 (model 10X or 10U)
v 1724 (model 1Xx, where x is an alphanumeric character)
Coupled with DS4000 storage subsystems such as the DS4100, DS4300, DS4400,
DS4500, and DS4800, you can configure RAID-protected storage solutions of up to
89.6 TB, providing economical and scalable storage for your rapidly growing
application needs for limited-access, data-reference storage capacity.
The EXP100 utilizes the latest SATA disk drive technology and is designed with
redundant 2 Gbps Fibre Channel connections to the DS4000 storage subsystem,
offering reliability and performance.
