IBM TotalStorage DS4000 EXP100 storage expansion unit

TotalStorage DS4000 EXP100 storage expansion unit The IBM TotalStorage DS4000 EXP100 Storage Expansion Unit is designed to enable the attachment of Serial Advanced Technology Attachment (SATA) disk drives for the IBM TotalStorage DS4300, IBM TotalStorage DS4400, and IBM TotalStorage DS4500. The new DS4000 EXP100 is a rack-mountable enclosure that supports up to fourteen of the new DS4000 250 GB SATA disk drive modules, offering up to 3.5 terabytes (TB) of capacity per enclosure.

Coupled with the DS4500 Disk Storage, it allows you to configure RAID protected storage solutions of up to 56 TB, or up to 28 TB with the DS4300, to help provide economical and scalable storage for your rapidly growing application needs for limited access, data reference capacity. The EXP100 utilizes SATA technology and is designed with redundant 2 Gbps Fibre Channel connections to the DS4000, supporting increased reliability and performance as compared to older, nonredundant parallel Advanced Technology Attachment (ATA) products.

DS4000s with EXP100 SATA disks build upon the highly successful and widely established base of DS4000s. They can be added to storage area networks to satisfy the needs of various fixed content, data reference applications that require large amounts of storage capacity but do not have the high utilization and access characteristics satisfied by Fibre Channel disk drive storage. Users will continue to have the advantages of the DS4000 Storage Manager's common, centralized management interface for handling both classes of storage needs.
