storage management station
A system that is used to manage the
storage system. A storage management
station does not need to be attached to
the storage system through the
fibre-channel input/output (I/O) path.
storage partition
Storage system logical drives that are
visible to a host computer or are shared
among host computers that are part of a
host group.
storage partition topology
In the DCS3860 Storage Manager client,
the Topology view of the Mappings
window displays the default host group,
the defined host group, the host
computer, and host-port nodes. The host
port, host computer, and host group
topological elements must be defined to
grant access to host computers and host
groups using logical drive-to-LUN
mappings.
striping
Splitting data to be written into equal
blocks and writing blocks simultaneously
to separate disk drives. Striping
maximizes performance to the disks.
Reading the data back is also scheduled
in parallel, with a block being read
concurrently from each disk then
reassembled at the host.
subnet
An interconnected but independent
segment of a network that is identified by
its Internet Protocol (IP) address.
sweep method
A method of sending Simple Network
Management Protocol (SNMP) requests
for information to all the devices on a
subnet by sending the request to every
device in the network.
switch A fibre-channel device that provides full
bandwidth per port and high-speed
routing of data by using link-level
addressing.
switch group
A switch and the collection of devices
connected to it that are not in other
groups.
switch zoning
See zoning .
system name
Device name assigned by the vendor's
third-party software.
TCP See Transmission Control Protocol .
TCP/IP
See Transmission Control Protocol/Internet
Protocol .
terminate and stay resident program (TSR
program)
A program that installs part of itself as an
extension of DOS when it is executed.
topology
The physical or logical arrangement of
devices on a network. The three
fibre-channel topologies are fabric,
arbitrated loop, and point-to-point. The
default topology for the disk array is
arbitrated loop.
TL_port
See translated loop port .
transceiver
A device that is used to transmit and
receive data. Transceiver is an
abbreviation of transmitter-receiver.
translated loop port (TL_port)
A port that connects to a private loop and
allows connectivity between the private
loop devices and off loop devices (devices
not connected to that particular TL_port).
Transmission Control Protocol (TCP)
A communication protocol used in the
Internet and in any network that follows
the Internet Engineering Task Force (IETF)
standards for internetwork protocol. TCP
provides a reliable host-to-host protocol
between hosts in packed-switched
communication networks and in
interconnected systems of such networks.
It uses the Internet Protocol (IP) as the
underlying protocol.
Transmission Control Protocol/Internet Protocol
(TCP/IP)
A set of communication protocols that
provide peer-to-peer connectivity
functions for both local and wide-area
networks.
trap In the Simple Network Management
Protocol (SNMP), a message sent by a
managed node (agent function) to a
management station to report an
exception condition.
