2-3 Previously, implementing mass storage controller redundancy required duplication of the mass storage controllers, as well as the disk drives. By pairing OSCRO with RAID 5 arrays, you gain the benefits of fault tolerance for the disks and the controllers without the additional costs of complete disk drive redundancy. OSCRO extends the reliability of Windows NT servers by ensuring continuing operation of the system, even when a mass storage controller fails. The Compaq Online Storage Controller Recovery Utility for Windows NT provides a means of managing the mass storage controllers of the entire Windows NT network from a single management station. OSCRO is a natural partner for Compaq PCI Hot Plug technology. The combination of the two eliminates the need to shut the system down when a mass storage controller fails. OSCRO permits the system to continue operating after a controller failure, and PCI Hot Plug technology allows replacement of the failed controller without shutting the system down.
