1-2 2-Gigabit Disk-Array Enclosure (DAE2) Hardware Reference
The DAE2 (2-gigabit disk-array enclosure) is a highly available,
high-performance, high-capacity storage system that uses a Fibre
Channel Arbitrated Loop (FC-AL) as its interconnect interface. An
enclosure connects to another DAE2 or a processor such as a CX700,
CX500, or CX300, and is managed by storage-system software in
RAID (Redundant Array of Independent Disk) configurations. The
enclosure is only 3U (5.25 inches) high, but can include 15 hard disk
drive/carrier modules. Its modular, scalable design allows for
additional disk storage as your needs increase. The examples and
illustrations in this manual show the rackmounted DAE2 in a
standard 40U EMC cabinet.
EMC produces two types of DAE2. The standard version includes
high-performance Fibre Channel disk drives and FC-AL link control
cards to manage them. The DAE2-ATA (Advanced Technology
Attachment) version uses economical, high-capacity ATA disk drives
and FC-to-ATA link control cards to manage the disks and provide an
interface between the FC-AL and the drives.
