Symantec 5.1 manual availability and scalability. Also called virtual SAN or VSAN

50 CommandCentral Glossary

administrative operations on resources, including starting, stopping, restarting, and monitoring at the service group level.

Veritas NetBackup A Symantec product family that provides a fast, reliable backup and recovery solution for environments ranging from terabytes to petabytes in size. The term NetBackup refers to either of two products that interact with the CommandCentral Storage product: Veritas NetBackup DataCenter and Veritas NetBackup BusinesServer.

Veritas Volume Manager A Symantec product installed on storage clients that enables management of physical disks as logical devices. Veritas Volume Manager enhances data storage management by controlling space allocation, performance, data availability, device installation, and system monitoring of private and shared systems.

virtual fabric	A storage area network (SAN) technology in which a group of switches and other
	objects constitute a hardware-based, isolated environment within a physical fabric.
	Virtual fabrics create multiple, isolated SAN environments within a physical SAN
	fabric in order to enable more efficient use of the SAN, especially in terms of
	availability and scalability. Also called virtual SAN or VSAN.
virtual hub	A set of switch ports on the same fabric that are placed into a logical grouping
	and use an address spoofing mechanism to emulate a Fibre Channel Arbitrated
	Loop (FC-AL) hub. A virtual hub can be comprised of all the ports on a single switch
	or several ports on one or more switches. It is used primarily to allow older
	loop-only devices to be attached to a switched fabric and be accessible as though
	they were fabric capable.
virtual IP address	A unique IP address associated with a VCS cluster. This address can be used on
	any system in the cluster, along with other resources in the VCS cluster service
	group. A virtual IP address is different from a system’s base IP address, which
	corresponds to the system’s host name. See also IP address.
virtual machine	An environment or software container that does not physically exist but is created
	in another environment. A virtual machine can run its own operating systems
	and applications as if it were a physical computer.
virtual SAN	See virtual fabric.
virtualization	A method of representing one or more objects, services, or functions as a single
	abstract entity so that they can be managed or acted on collectively. An example
	of virtualization is the creation of a virtual fabric from a switch and associated
	storage resources as a means of controlling access and increasing scalability in
	the storage network.
virtualization server	A server that hosts multiple virtual machines with the help of a virtualization
	application, such as VMware. The virtualization server provides virtualization
	data to the Management Server.
visible storage	Allocated LUNs that are zoned to a host.
