Access Control sets an accessible logical disk for each host (HBA) or each port.
The use of the access control feature enables the division of logical disks into logical disk groups. The
division extends the flexibility of the system configuration. The feature also ensures data protection

Dedicated software (AccessControl - NEC Storage S2900), which is purchased separately, is necessary
