Parallel Database Cluster Model PDC/O5000 for Oracle8i and Windows 2000 Administrator Guide
Fabric
A complex set of interconnections through which there can be
multiple and (to the user) unknown paths from point to point. The
term “fabric” is used to refer to the X or Y portion of the internal or
external network; for example, the X fabric.
Fault tolerance
A characteristic that allows continued operation of a computer entity
when a fault (or failure) is encountered. Fault tolerance applies to a
computer component, an individual computer, or a cluster of
computers, primarily through designing redundant elements into the
entity.
FC-AL
See Fibre Channel Arbitrated Loop (FC-AL).
Fibre Channel
An IEEE standard for providing high-speed data transfer among
workstations, mainframes, supercomputers, desktop computers,
storage devices, and display devices.
Fibre Channel
Arbitrated Loop
(FC-AL)
A storage area network (SAN) topology that uses FC-AL storage
hubs to arbitrate I/O requests between cluster nodes and shared
storage resources.
Fibre Channel
Fabric
A storage area network (SAN) topology that uses Fibre Channel SAN
Switches to connect cluster nodes with shared storage resources.
Fibre Channel
Fabric Setup
Software (FCSS)
utility
Installs the HSZDISK driver and other shared storage subsystem
device drivers required for Microsoft Windows 2000 clusters and
sets the Arbitrated Loop Physical Address (ALPA) and registry. The
FCSS utility is located on the Solutions Software for ACS CD.
Heartbeat
A signal transmitted between cluster nodes to indicate whether the
nodes are operating.
High availability
A term used to identify a computer system that can continuously
deliver services to its clients 99.9 percent of the time (no more than
8.5 hours of downtime per year).
Hot-pluggable
A computer component that can be removed and replaced without
powering down the system.
Hot spare
A computer component that is powered on, not actively processing
data, and awaiting a request to take over operation of a failed
component.
