EVA storage presentation
EVA uses virtualization technology, which organizes physical disks into disk groups.
Each disk group is a storage pool from which virtual disks are allocated. A virtual
disk is limited by the boundaries of a disk group, but may span over any number of
physical disks within one disk group. You cannot control the exact allocation of virtual
disks on physical disks, but you can influence it by choosing different protection
characteristics. For that, RAID technology is used, which provides various levels of
data redundancy, speed, and access time.
