Glossary

Data Sharing
A SAN solution in which files on a
storage device are shared between multiple hosts.
DATABASE 2 (DB2®)
A relational database
management system. DB2 Universal Database™ is
the relational database management system that is
Web-enabled with Java support.
Device driver
A program that enables a computer
to communicate with a specific device, for example,
a disk drive.
Disaster Recovery Planning
Functions as a
logical subset to the BCP process. IT operation’s
teams manage the DRP process to ensure
continuity of operations in the event of a wide variety
of disaster scenarios
Disk group
A set of disk drives that have been
configured into one or more logical unit numbers.
This term is used with RAID devices.
Disk Mirroring
A fault-tolerant technique that
writes data simultaneously to two hard disks using
the same hard disk controller.
Disk Pooling
A SAN solution in which disk storage
resources are pooled across multiple hosts rather
than be dedicated to a specific host.
DRP
See Disaster Recovery Planning
duplex
Pertaining to communication in which data
or control information can be sent and received at
the same time, from the same node. Contrast with
half duplex
.
DWDM
See Wave Division Multiplexing.
E
E_Port
An E_Port is used as an inter-switch
expansion port to connect to the E_Port of another
Fibre Channel switch, in order to build a larger
switched fabric.
Enterprise network
A geographically dispersed
network under the backing of one organization.
ESCON®
Enterprise Systems Connection
Architecture®. A zSeries® 900 and S/390®
computer peripheral interface. The I/O interface
utilizes S/390 logical protocols over a serial interface
that configures attached units to a communication
fabric.
Event
In the Tivoli environment, any significant
change in the state of a system resource, network
resource, or network application. An event can be
generated for a problem, for the resolution of a
problem, or for the successful completion of a task.
Examples of events are: the normal starting and s
ping of a process, the abnormal termination of a
process, and the malfunctioning of a server.
F
F_Port
An F_Port is a fabric port that is not loop
capable. It is used to connect a N_Port to a switch.
Fabric
The Fibre Channel employs a fabric to
connect devices. A fabric can be as simple as a
single cable connecting two devices. The term is
often used to describe a more complex network
utilizing hubs, switches, and gateways.
FC
See Fibre Channel.
FCIP
See Fibre Channel over IP.
FCP
See Fibre Channel protocol.
FCS
See Fibre Channel standard.
Fiber optic
The medium and the technology
associated with the transmission of information
along a glass or plastic wire or fiber.
Fibre Channel
A technology for transmitting data
between computer devices at a data rate of up to 2
Gbps. It is especially suited for connecting computer
servers to shared storage devices and for
interconnecting storage controllers and drives.
Fibre Channel Arbitrated Loop
A reference to the
FC-AL standard, a shared gigabit media for up to
127 nodes, one of which can be attached to a switch
fabric. See also arbitrated loop and loop topology.
