	product includes several explorers that are used to locate resources and discover
	information about them. See also discovery.

Fibre Channel	A collective name for the fibre optic technology that is commonly used to set up
	a storage area network (SAN) or virtual fabric (VSAN). A set of standards capable

	supports point-to-point, loop, and fabric topologies.

	which a user can limit the number and types of objects displayed. Also, a way in
	which an administrator can limit the amount of data collected by the Exchange
