  • Creating logical disk drives for raid subsystems
    Patent number: 9811454
    Abstract: A computer storage system includes multiple disk trays, each disk tray holding two or more physical disks. The disks on a single tray are virtualized into a single logical disk. The single logical disk reports to the RAID (redundant array of inexpensive disks) subsystem, creating the impression that there is one large capacity disk. In one implementation, each disk in the tray is allocated to a different RAID group. By allocating the disks in a tray to different RAID groups, if the tray is removed, only a portion of several different RAID groups are removed. This arrangement permits a simple reconstruction of the RAID groups if a disk tray is removed from the system.
