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

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. See also

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.
redundant array of independent disks
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.
