Disk array enclosures
The D-Series and U-Series Appliance include disk array enclosures (DAEs). The DAE is
a drawer that slides in and out of the 40U rack. The storage disk drives, I/O modules,
and cooling modules are located inside of the DAE.
Use the power and weight calculator to plan for the weight of the configuration.
ECS Appliances use two types of DAE:
l
The D-Series includes the Pikes Peak (dense storage) enclosure, which can hold
up to 98 disks.
l
The U-Series includes the Voyager DAE, which can hold up to 60 disks.
