Can ATA RAID Make It to the Enterprise?
For the most part, the deployment of ATA RAID units has been limited to the realm of overclockers and small businesses with extremely low budgets, but times are changing.For the most part, the deployment of ATA RAID units has been limited to the realm of overclockers and small businesses with extremely low budgets, but times are changing. With shrinking IT budgets and with advances in inexpensive Advanced Technology Attachment drive technology, ATA RAID devices enterprise time may be coming. (ATA is the connector interface for IDE drivesstandard drives found in virtually all desktop machines and some low-end workstations.) While I doubt that high-end shops will ever stray from enterprise-class Fibre Channel and SCSI implementations as their primary form of data storage, inexpensive ATA devices can be used as high-speed tape replacements to provide backup services.
One new product that addresses this market comes from Nexsan Technologies (www.nexsan.com). The InfiniSAN D2D (for Disk to Disk) backup system uses Nexsan-developed firmware and code to create a backup system with true hot-swap abilities and the complete redundancy that are usually found only in SCSI and Fibre Channel RAID units.
