A collection of interdependent resources that logically
represents a clustered client/server function. This is a
user-definable entity used by Microsoft Cluster Server
(MSCS) software.
A hardware device that facilitates communications
between a host and one or more devices organized on
an RA4000.
A device that provides an interface between a host
system (server) and storage system or other devices
connected on a fibre channel arbitrated loop or fabric.
A storage device including disk drives and one or
more resident array controllers.
A misunderstood command sent by software that
causes processing to halt.
An automatically assigned address that comes from an
unused IP address pool. When the client/server
session ends, the IP address is returned to the pool.
The server can use fewer IP addresses to
communicate with clients. Clients do not need to
provide a hard-coded address to the server.
A standard network protocol that primarily operates
on a physical level, using network interface cards and
cabling to transmit data between computers. Transfer
rates are normally 1,000 or 10,000 megabits per
second.
The process of moving the operation of a previously
failed cluster group from the secondary cluster node
back to the primary node.
The process of moving the operation of a cluster
group from the primary node to the secondary node in
the same cluster.
A design concept that allows continued operation of a
computer entity when a fault (or failure) is
encountered. Tolerance is achieved primarily by
designing redundant elements into the entity.
