VMware Terms
Virtual Switch VMware Infrastructure lets you create abstracted
network devices called virtual switches
(vSwitches). A vSwitch can route traffic internally
between virtual machines and link to
external networks.
Virtual Disk A file or set of files that appears as a physical disk
drive to a guest operating system. These files can
be on the host machine or on a remote file system.
VirtualCenter Server A service that acts as a central administrator for
VMware servers connected on a network. This
service directs actions on the virtual machines
and the virtual machine hosts. VirtualCenter
Server is the working core of VirtualCenter.
SAN/iQ Terms
Cluster A cluster is a grouping of storage nodes that
create the storage pool from which you create
volumes.
Failover Manager A specialized manager running as a VMware
guest operating system that allows you to place a
quorum tie-breaker node into a 3rd location in the
network to provide for automated failover/failback
of the Multi-Site SAN clusters. The Failover
Manager is designed to run on VMware Server,
which is installed on your own hardware, separate
from the SAN hardware.
Management Group In the SAN/iQ software, a collection of one or more
storage nodes which serves as the container
within which you cluster storage nodes and create
volumes for storage.
