ABSTRACT:
Disclosed are ways of providing a highly flexible high availability storage system. Disk drive carriers for insertion into enclosures in a storage system include several disk drives. The enclosures accept carriers that include drives of different sizes, and drives compatible with different storage technologies, for instance Fibre Channel, SATA, or SAS. Drives oriented in their carriers in a manner that allows them to be connected to a common medium via identical flex circuits that are configured based on the orientation of the drives. Redundant controllers include redundant serial buses for transferring management information to the carriers. The carriers include a controller for monitoring the multiple serial buses and producing storage technology specific management commands for the disk drives.
