    In a dual-controller system, when a controller fails, the partner controller assumes temporary ownership of the failed controller's vdisks and resources. If a fault-tolerant cabling configuration is used to connect the controllers to drive enclosures and hosts, both controllers' LUNs are accessible

    controller host ports for access by hosts. The storage system presents only volumes, not vdisks, to hosts. You can create vdisks with or without volumes by using the Provisioning Wizard, or you can create vdisks manually. Best practices for creating vdisks include: • To maximize capacity, use disks

The external port may be a port in an I/O adapter (such as an FC HBA) in a server, or a port in a network switch. The controllers automatically discover hosts that have sent an inquiry command

While a snapshot is a point-in-time logical copy of a volume, the volume copy service creates a complete "physical" copy of a volume within a storage system. It is an exact copy
