RAID has been a system implemented in high-end servers and workstations for some time. Until recently however, it was not viable for most organizations. Now that it is an option, learn the ins-and-outs to determine how your organization can benefit.
Of course, a large part of making RAID affordable lies not only in reducing the cost of the controller itself, but also in making it compatible with less-expensive hard disks. SCSI RAID controllers have been available for quite some time, but most organizations cannot afford a single SCSI drive, let alone multiple drives. Thus, the next logical step in making RAID affordable would be an IDE RAID controller. With that in mind, last year Promise Technology introduced its FastTrak. Following its lead, Iwill also recently announced sIDE RAID66, an UltraDMA-66 IDE RAID controller.
Comprehensive reviews of both products can be found on HardwareCentral. This tutorial will primarily discuss the concepts of RAID.
