RAID
Redundant array of independent disks. A collection of disk drives that appear as a single volume to the
server and are fault tolerant through mirroring or parity checking.
receiver
A device that performs detection and signal processing.
redundancy
Multiple instances of a component to maintain high availability (HA).
remote switch
An optional product for long-distance fabrics, requiring a Fibre Channel-to-ATM or SONET gateway.
repeater
A circuit that uses a recovered clock to regenerate and transmit an outbound signal.
route
In a fabric, the communication path between two switches. Might also apply to the specific path taken by
an individual frame, from source to destination.
routing
The assignment of frames to specific switch ports, according to frame destination.
RW
Read/write. Refers to access rights.
SAN
Storage area network. A network of systems and storage devices that communicate using Fibre Channel
protocols. See also fabric.
SAN architecture
The overall design of a storage network solution, which includes one or more related fabrics, each of which
has a topology.
SAN port count
The number of ports available for connection by nodes in the entire SAN.
scalability
One of the properties of a SAN; the size to which a SAN topology can grow port and switch counts with
ease.
SCN
State change notification. Used for internal state change notifications, not external changes. This is the
switch logging that the port is online or is an Fx_port, not what is sent from the switch to the Nx_Ports.
SCSI
Small Computer Systems Interface. A parallel bus architecture and a protocol for transmitting large data
blocks to a distance of 15 to 25 meters.
Secure Fabric OS
A separately sold HP feature that provides advanced, centralized security for a fabric.
security policy
Rules that determine how security is implemented in a fabric. Security policies can be customized through
HP Secure Fabric OS or HP Fabric Manager.
