New Advanced RAID Level for Today's Larger Storage Capacities:
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
Array 5300
st
the 1 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.
