Disk Enclosure Components The SureStore E Disk System SC10, or disk enclosure, is a high availability Ultra2 SCSI storage product. It provides an LVD SCSI connection to the controller enclosure and ten slots on a single-ended backplane for high-speed, high-capacity LVD SCSI disks. Six disk enclosures fully populated with 9.1 Gbtye disks provide 0.54 Tbytes of storage in a 2-meter System/E rack. When fully populated with 73 Gbyte disks, the array provides over 3 Tbytes of storage. These values represent maximum storage; usable storage space will vary depending on the RAID level used. The disk enclosure consists of modular, redundant components that are easy to upgrade and maintain. See Figure 2. Disks, fans, power supplies, and Bus Control Cards (BCCs) are replaceable parts that plug into individual slots in the front and back of the disk enclosure. Redundant fans, power supplies, and disk modules can be removed and replaced without interrupting storage operations. In addition, a single disk within a volume group can be replaced while the system is on. 20 Disk Enclosure Components
