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.
