    For a complete description of product models, see the “Components” chapter within the Setup Guide. AssuredSAN 4004 Series enclosures support both traditional linear storage and new virtual storage, which uses paged-storage technology. For linear storage, a group of disks with an assigned RAID level is called a vdisk or linear disk group.
