STP. See shielded twisted pair.
T
target. A collection of logical units that are directly addressable on the network. The target corresponds to the server
in a client-server model.
TCP. See Transmission Control Protocol.
TCP/IP. See Transmission Control Protocol/Internet Protocol.
teaming. The grouping of two to four ports or adapters to increase transmission and reception throughput. Teaming
creates a single, high-speed, fault-tolerant link that provides load balancing for both outbound and inbound traffic.
Tivoli Storage Manager (TSM). A client/server product that provides storage management and data access services
in a heterogeneous environment.
Transmission Control Protocol (TCP). In TCP/IP, a host-to-host protocol that provides transmission in an internet
environment. TCP assumes Internet Protocol (IP) is the underlying protocol.
Transmission Control Protocol/Internet Protocol (TCP/IP). The Transmission Control Protocol and the Internet
Protocol, which together provide reliable end-to-end connections between applications over interconnected networks of
different types.
True Image data view. A data view that allows the file to be restored in the event of accidental deletion. It consists
of point-in-time images that provide a near-instant virtual copy of an entire storage volume.
TSM. See Tivoli Storage Manager.
U
universal serial bus (USB). A serial-interface standard for telephony and multimedia connections to personal
computers.
unshielded twisted pair (UTP). A cable medium with one or more pairs of twisted insulated copper conductors
bound in a single plastic sheath.
USB. See universal serial bus.
V
virtual local area network (VLAN). A logical association of switch ports based upon a set of rules or criteria such as
MAC addresses, protocols, network address, or multicast address. This concept permits resegmentation of the LAN
without requiring physical rearrangement.
virtual logical unit number (VLUN). A subset of a logical drive.
VLAN. See virtual local area network.
VLUN. See virtual logical unit number.
volume. (1) A unit of storage on disk, tape, or other data-recording media. (2) A logical disk visible to an appliance
over a storage network. A volume is a member of a single storage network of 1 - n fabrics. It can have 1 - n path
groups of 1 - n equivalent paths.
W
Windows Internet Naming Service (WINS). A Microsoft program that provides a distributed database for registering
and querying dynamic NetBIOS names to IP address mapping in a routed network environment.
WINS. See Windows Internet Naming Service.
