storage management server in a fabric. Each installation is a management agent.
The client for the agent is a standard browser.
EMI Electromagnetic Interference. The impairment of a signal by an electromagnetic
disturbance.
EMU Environmental Monitoring Unit. An element which monitors the status of an
enclosure, including the power, air temperature, and blower status. The EMU
detects problems and displays and reports these conditions to a user and the
controller. In some cases, the EMU implements corrective action.
enclosure A unit used to hold various storage system devices such as disk drives, controllers,
power supplies, blowers, an EMU, I/O modules, or blowers.
enclosure address An Enterprise storage system bus that interconnects and identifies controller
bus enclosures and disk drive enclosures by their physical location. Enclosures within
a reporting group can exchange environmental data. This bus uses enclosure ID
expansion cables to assign enclosure numbers to each enclosure. Communications
over this bus do not involve the Fibre Channel drive enclosure bus and are,
therefore, classified as out-of-band communications.
enclosure number
One of the vertical rack-mounting positions where the enclosure is located. The
(En) positions are numbered sequentially in decimal numbers starting from the bottom
of the cabinet. Each disk enclosure has its own enclosure number. A controller
pair shares an enclosure number. If the system has an expansion rack, the
enclosures in the expansion rack are numbered from 15 to 24, starting at the
bottom.
enclosure services Those services that establish the mechanical environmental, electrical
environmental, and external indicators and controls for the proper operation and
maintenance of devices with an enclosure as described in the SES SCSI-3
Enclosure Services Command Set (SES), Rev 8b, American National Standard
for Information Services.
