Overview

The IBM TotalStorage DS4700 / DS4700 Express is a midrange 4-Gbps storage system designed to grow with your business. The DS4700 has (16) drive bays and can support the addition of (6) EXP810 expansion enclosures to install 112 disk drives. You may select from high speed FibreChannel E-DDM (Enhanced Disk Drive Modules) or high-capacity SATA E-DDMs for nearline storage requirements. With the appropriate licensing, SATA and FC disk modules can be intermixed on the same DS4700.

You can preserve your investment in your DS4300 and DS4500 equipment by utilizing your older 2Gbps EXP710 enclosures.

Please note which enclosure you are using before ordering disk modules. EXP810 disk modules are not compatible with EXP710 expansion arrays. The reverse is also true.

Expansion Shelf	Maximum # of Enclosures	Drive Type
EXP700	7 Expansion Enclosures x 14 Drives per Enclosure
EXP710
EXP810 and internal	6 Enclosures x 16 Drives per Enclosure

The IBM EXP810 expansion unit with ESM firmware 9898 or higher is supported attaching to the DS4300, DS4500, DS4700, and DS4800 subsystems with controller firmware version 6.23.xx.xx and later. Version 9898 and higher is also required to support the intermix of EXP710 and EXP810 with EXP100 storage expansion enclosures behind the DS4300, DS4500, DS4700 and DS4800 storage subsystems with controller firmware version 6.23.xx.xx, 6.60.xx.xx and 7.xx.xx.xx and to support the intermixing of the Fibre Channel and SATA E- DDMs within the EXP810 drive expansion enclosure in any storage subsystem configuration.
