Compaq ProLiant CL380 New Advanced RAID Level for Today's Larger Storage Capac - Page 3

New Advanced RAID Level for Today's Larger Storage Capacities: 3 What customers can expect from Compaq RAID ADG solution RAID ADG is a new advanced RAID level that increases the number of sets of parity, creating multiple sets striped across the disks to provide unparalleled fault tolerance, greater than RAID 1 or RAID 5, and at a lower cost implementation than RAID 1. Designed for support on the Smart Array 5300 Controller, RAID ADG is ideal for applications requiring large volumes. Available in the 1st quarter of 2001, with the Smart Array 5300 Controller, RAID ADG can safely protect an array up to 56 total drives, ensuring customers of a powerful solution with high fault tolerance. Some customers' needs now require a fault tolerance scheme that would provide higher reliability than RAID 5 at a lower cost than RAID 1. Compaq recognized these customers' needs for high capacity RAID protection on a single storage array that could span a large number of disks. Customers can now complete their server/storage solution with a Compaq innovation - Advanced Data Guarding (RAID ADG) system. RAID ADG Features and Benefits ✔ RAID ADG can tolerate multiple simultaneous drive failures without downtime or data loss.1 ✔ Ideal for applications requiring large logical drives ✔ Can safely protect an array up to 56 total drives ✔ Greater fault tolerance than RAID 1 or RAID 5 ✔ Lower implementation cost than RAID 1 ✔ Supports Online Spare Drive ✔ Supports Online RAID Level Migration from RAID 1 or RAID 5 1 A RAID ADG Enabler Module must be attached to the controller to enable RAID ADG configuration via Array Configuration Utility (ACU). The module is shipped with the 128MB cache board. 13JE-1000A-WWEN
