3 Enterprise Virtual Array hardware components This chapter describes the Enterprise Virtual Array hardware components. Fibre Channel drive enclosures The drive enclosure contains the disk drives used for data storage. A storage system includes multiple drive enclosures. The major components of the enclosure are: • 3U enclosure • Dual redundant, active-to-active 2 Gbps FC loops • 2.125-Gb, dual loop, 14-drive enclosure • Dual 2 Gbps FC I/O modules (A and B loops) • Copper Fibre Channel cables • Fibre Channel disk drives and drive blanks • Dual redundant power supplies • Dual redundant blowers • Cache batteries • Environmental Monitoring Unit (EMU) Enclosure layout The disk drives mount in bays in the front of the enclosure. The bays are numbered sequentially from left to right. A drive is referred to by its bay number. Enclosure status indicators are located in the lower-right, front corner. Figure 6 (page 26) shows the front and rear views of the FC drive enclosure. Figure 6 FC drive enclosure-front and rear views 1. Drive bay 1 3. EMU 5. Blower 1 7. Blower 2 9.
