• Disk Enclosure for up to 10 high-performance hot swap IBM Ultra 2 (LVD) disk drives, including both 7,200 and 10,020 rpm options
• Capacity ranging from 9.1 GB to 364 GB, utilizing 9.1, 18.2, or 36.4 GB disk drives
• Rack model
• Support for the 7046-B50 and other RS/6000 servers

The IBM Expandable Storage Plus (Exp Plus) disk enclosure provides low-cost disk storage for RS/6000 servers, especially for the 7046-B50. In addition, Exp Plus:

• Offers space for up to ten hot swap Ultra 2 (LVD) disk drives, including IBM's high performance 9.1, 18.2 (both 7,200 rpm and 10,020 rpm drives are available), and 36.4 (7,200 rpm) GB Ultrastar drives.
• Is designed to meet the needs of RS/6000 customers that have external disk capacity requirements and desire to use a Ultra 2 (LVD) interface. When combined with the IBM PCI 3-channel Ultra SCSI RAID Adapter, high performance and high availability are available.
• HACMP support is available in clustered server environments operating in non-concurrent modes.

IBM's Expandable Storage Plus provides leading-edge technology at a very affordable price.

IBM's Expandable Storage Plus (Exp Plus) is designed to meet the needs of many different types of customers, including those customers that are looking for standalone storage for a single server, rack mounted storage for several servers, or want to use SCSI technology as the connectivity option. Exp Plus provides excellent performance, high availability (when combined with a RAID based host bus adapter), enclosure services to ensure that problems are reported to the server (at customer selectable intervals), and an attractive price.

Exp Plus supports a wide variety of disk drives, including many of IBM's leading Ultrastar drives. Options are available for both 7,200 rpm technologies (9.1, 18.2, and 36.4 GB) and 10,020 rpm technologies (9.1 and 18.2 GB). These drives can be mixed together in the same enclosure. When connected to a RAID host bus adapter, such as the Ultra SCSI RAID Adapter, data protection and high performance are possible.

Exp Plus includes a single power supply (a second is available as an option, thus creating redundant power), space for up to ten disk drives, and SCSI Enclosure Services (SES). Exp Plus can be mounted into one of several racks, including the 7104 S00, 7015 R00, 7202-900, and the 2101-100. A tower (stand alone model) option is available as well. Using 36.4 GB disk drives, Exp Plus can support up to 364 GB of unprotected disk storage. Using RAID technology provides data protection, but does require some amount of space, depending on the RAID level selected.
