DuraStor 6220SS/7220SS Installation and User's Guide O ownership In an active-active configuration, each controller has ownership of arrays and dedicated spares. If one controller fails, the other controller assumes temporary ownership of its arrays and dedicated spares. P PSU Stands for Power Supply Unit. S SAF-TE (SCSI Accessed Fault-Tolerant Enclosure) The SAF-TE specification is an open specification designed to provide a comprehensive standardized method to monitor and report status information on the condition of disk drives, power supplies, cooling systems, and other components used in highavailability LAN servers and subsystems. See also enclosure. SAN (Storage Area Network) A high-speed, special-purpose network that interconnects different data storage devices with data servers, on behalf of a larger network of users. SCSI (Small Computer System Interface) SCSI is an industry standard for connecting peripheral devices and their controllers to an initiator. Storage devices are daisy-chained together and connected to an HBA. The HBA provides a shared bus that attached peripherals use to pass data to and from the host system. Examples of devices attached to the HBA include disk drives, CD-ROM drives, optical disk drives, and tape drives. In theory, any SCSI device can be plugged into any SCSI controller. See also HBA (host bus adapter). SCSI adapter A SCSI adapter is a 16-bit fast/wide or 8-bit narrow, single-ended or differential physical connection between a router and SCSI devices. Each SCSI adapter supports up to 16 (fast/wide) or 8 (narrow) SCSI devices, including itself. Glossary-4
