New Advanced RAID Level for
Today's Larger Storage Capacities:
Advanced Data Guarding
Abstract: The purpose of this paper is to communicate the
advantages of utilizing Compaq’s new RAID innovation, Advanced
Data Guarding (ADG).
RAID ADG provides a new level of fault protection at a high level of
capacity utilization. Designed to be first supported on the Smart
Array 5300 Controller, RAID ADG is ideal for applications
requiring larger storage volumes, delivering a powerful fault tolerant
solution at a lower implementation price.
Every Compaq server customer implementing an array with 8 or
more hard disk drives should consider this new RAID level.
This innovative Compaq solution for the Smart Array 5300 is patent pending
and is not a feature of competitors’ PCI RAID products.
