Logical resources are all of the resources defined on the ASC Server, including
SAN Resources, NAS Resources, Replica Resources, and Snapshot Groups.
SAN and NAS logical resources consist of sets of storage blocks from one or
more physical hard disk drives. This allows the creation of logical resources that
contain a portion of a larger physical disk device or an aggregation of multiple
physical disk devices.
Clients do not gain access to physical resources; they only have access to logical
resources. This means that an administrator must configure each physical
resource to one or more logical resources so that they can be assigned to the
clients.
When you highlight a SAN or NAS Resource, you will see a small icon next to
each device that is being used by the resource.
