Glossary public device A loop device that can transmit a fabric login command (FLOGI) to a switch, receive acknowledgement from the switch's login server, register with the switch's name server, and communicate with fabric-attached devices. Public devices communicate with fabric-attached devices through the switch's bridge port (B_Port) connection to a Director or Switch. Contrast with private device. public loop A public loop is connected to a switched fabric (through the switch bridge port (B_Port)), and the switch has an active embedded fabric loop port (FL_Port) that is user transparent. All devices attached to the loop can communicate with each other, and public devices attached to the loop can communicate with fabric-attached devices. Contrast with private loop. pull-down menu See drop-down menu. RAID See redundant array of independent disks. RAM See random access memory. random access memory RAM. A group of computer memory locations that is numerically identified to allow high-speed access by the controlling microprocessor. A memory location is randomly accessed by referring to its numerical identifier (D). Contrast with redundancy.

redundancy

Performance characteristic of a system or product whose integral components are backed up

by identical components to which operations will automatically failover in the event of a

component failure. Redundancy is a vital characteristic of virtually all high-availability (24

hours/7 days per week) computer systems and networks.

RAID. Grouping of hard drives in a single system to provide greater performance and data

integrity. RAID systems have features that ensure data stored on the drives are safe and

quickly retrievable.
