Raid, Rrtov, Rscn, San | HP Brocade 4Gb SAN c-Class BladeSystem

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.
request rate	The rate at which requests arrive at a servicing entity.
route	With respect to a fabric, the communication path between two
	switches. May 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.
RR_TOV	Resource recovery time-out value. The minimum time a target
	device in a loop waits after a LIP before logging out a SCSI
	initiator.
RSCN	Registered state change notiﬁcation. A switch function that
	allows notiﬁcation of fabric changes to be sent from the switch
	to the speciﬁed nodes.
SAN	Storage area network. A network of systems and storage
	devices that communicate using FC protocols.
SDRAM	Synchronous dynamic random access memory. The main
	memory for a switch. See also switch.
sequence	A group of related frames transmitted in the same direction
	between two N_ports.
service rate	The rate at which an entity can service requests.
single mode	The ﬁber optic cabling standard that corresponds to distances
	up to 10 km between devices.
SNMP	Simple Network Management Protocol. An Internet
	management protocol that uses either IP for network-level
	functions and UDP for transport functions, or TCP/IP for
	both. SNMP can be made available over other protocols
	(such as UDP/IP) because it does not rely on the underlying
	communication protocols. See also MIB, trap (SNMP).
SNS	Simple Name Server. A switch service that stores names,
	addresses, and attributes for up to 15 minutes, and provides
	them as required to other devices in the fabric. May also be
	referred to as a directory service.
switch	Hardware that routes frames according to FC protocol and is
	controlled by software.
