EMC Fibre Channel Disk-Array Processor Enclosure (DPE) Hardware Reference
The name for the printed-circuit board within the computer
chassis that allows the server to access the Fibre Channel loop
and thus the SP(s).
See FRU (field-replaceable unit).
A hardware assembly that can be replaced on site, instead of at
the point of manufacture.
H
Another name for Fibre Channel adapter.
See server.
See replace under power.
An FC_AL switching device that allows multiple servers and
targets, such as storage systems, to connect at a central point. A
single hub configuration appears as a single loop.
J
Another application for DAE (Disk Array Enclosure).
L
A CRU in an enclosure that connects Fibre Channel signalling to
the disk modules. Provides fiber channel connectivity between
the SP, disks, and other enclosures. It also provides bypass
capability for faulted or missing units, and monitors and controls
enclosure elements.
One or more disk modules (each having a head assembly and
spindle) bound into a group — usually a RAID Group. The
operating system sees the LUN, which includes one or more disk
modules, as one contiguous span of disk space.
M
See SP memory module.
