Currently in beta form and scheduled for launch in the second quarter of 2002, the Quantum DX30 is a rack-mounted, disc-based backup system that thinks it's a tape library. It can be installed in front of an existing tape backup system without having to change an administrator's backup policy.
The advantage of disc backup over tape backup is speed. While the DX30 is not designed to replace tape as an inexpensive method of archiving data, it is designed to help administrators meet their backup windows by storing data faster, said Quantum.
Data backed up to the DX30 can then be transferred to a tape archive without the pressure of a backup window.
The DX30 packs 3TBytes of storage capacity within a 3.5in rackable chassis and uses a development of the RAID approach to storage called Adaptive Disk Array Management (ADAM). Quantum said the DX30 was faster then current disc-to-disc storage backup systems, but has issued not figures to back up the claim.
The company described ADAM technology as "a completely different approach to disc storage that is optimised for large, high-speed data transfers," that is less expensive that standard RAID devices.
Tape storage has come under increasing scrutiny as the falling price of disc storage threatened to eat in to tape's share of the data storage market.
However, experts such as Steve DuPlessie of the Enterprise Storage Group have said high-speed disk storage systems such as the DX30 will work as an intermediary between primary storage and tape storage, which is still the least expensive way to archive data.
