	CommandCentral Glossary 37
CLARiiON storage group	In an EMC CLARiiON storage array, a set of addressable units (LUNs) defined so
	that an operator can perform one LUN masking operation for the entire set of
	LUNs rather than separately for each LUN. Contrast with storage group.
cluster	A set of hosts (each termed a node) that share a set of disks and are connected by
	a set of redundant heartbeat networks. A cluster can have from one to 32 member
	systems, or nodes. Also called VCS cluster. Specific to virtualization, one or more
	virtualization servers.
cluster communication	Communication between clusters using either of the two core communication
	protocols defined by Veritas Cluster Server: GAB and LLT. The communication
	takes place by means of heartbeat signals sent between systems or fast
	kernel-to-kernel broadcasts.
collector	A measurement representing a specific state or numerical value for objects in the
	storage network. The Alarm Service uses collectors to monitor and correlate status
	and performance information, using several different processes. The Alert Manager
	uses information gathered by collectors to trigger policy actions such as SMTP
	mail, console alerts, commands, and logging. See also policy.
Command Central	A program, used in earlier releases of the SANPoint Control and CommandCentral
Configuration Utility	Storage products, that scanned the storage network in order to identify potential
	configuration problems before installation. The program is no longer supported.
CommandCentral	A product offering designed to maximize the return on an enterprise’s storage
Storage	technology investment by providing tools with which a storage administrator can
	make the storage network or SAN operate as effectively as possible.

Storage Agent Push

Install Utility

A Windows-based utility with which you can install an agent that enables the collection of data through a variety of explorers. Using the Agent Push Install Utility, you can manage installs, upgrades, and uninstalls for multiple Windows-based managed hosts from one central location.

CommandCentral	A Server component (Windows service/UNIX daemon) that retrieves and correlates
Storage Alarm Service	SNMP and other data and sends alerts to the CommandCentral Storage Alert
	Manager for further processing using defined policies. The Alarm Service has a
	command-line interface—vxascmd—with which you can connect to an Alarm
	Service server to obtain server and object information and perform various Alarm
	Service commands and queries.
CommandCentral	A Server component that manages policies associated with objects on the storage
Storage Alert Manager	network. A policy associates certain sets of conditions with storage resources and
	defines actions to be taken when these conditions are detected. The Alert Manager
	is seamlessly integrated with the CommandCentral Storage product so that Console
	users can monitor, define, and modify policies.
CommandCentral	A graphical user interface that displays reports and other information for users
Storage Console	of the CommandCentral Storage product through a standard Web browser. The
