McDATA 3000 manual Storage Area Networking, Striping, Subnet, Synchronous, FC/SCSI Tape Pipelining

		Glossary
Storage Area Networking
	A high-speed network that establishes a direct connection between
	storage devices and servers, thereby externalizing storage from the
	the server and allowing information to be shared among multiple
	host servers without affecting performance of the primary network.
striping	A RAID (Redundant Array of Inexpensive Disks) term. The process
	of dividing a large logical block of data into multiple physical blocks
	of equal size for storage on multiple disk drives. See RAD and
	Redundant Array of Inexpensive Disks.
subnet	A network that is a component of a larger network.
switch	A mechanical, electrical or electronic device which opens or closes
	circuits, completes or breaks an electrical path, or selects paths or
	circuits. McDATA SAN systems use a serial switch (for example, a
	WTI or Penril device) to provide connectivity between an UltraNet
	Edge 3000 and a modem.
synchronous	Signals that are sourced from the same timing reference and have the
	same frequency.
FC/SCSI Tape Pipelining	Performs remote tape backup performance over extended distances
	using a new or existing IP or ATM (FC/SCSI only at this time)
	network, devices appear local to the server and sustained bandwidth
	is comparable to local performance up to thousands of miles.
Telnet	A program that allows you to connect to other computers on the
	Internet. Telnet is the terminal-remote host protocol developed for
	ARPAnet. The format of the telnet command is telnet
	address.domain or telnet address.domain interface #.
TCP/IP	Transmission Control Protocol/Internet Protocol. A special type of
	communication protocol used by some computer networks.
UBR	ATM Unspecified Bit Rate
VBR	ATM Variable Bit Rate
VCI	ATM Virtual Circuit Identifier
VPI	ATM Virtual Path Identifier
WAN	See Wide Area Network.
Wide Area Network	A computer and voice network that encompasses a geographical area
	including campuses, metropolitan areas, and combinations of such
	areas.
WWN	World Wide Name, a 64 bit unique identifier for nodes and ports in a
	fabric.
