Enterprise Virtual
Array The Enterprise Virtual Array is a product that consists of one or more storage systems. Each storage
system consists of a pair of HSV controllers and the disk drives they manage. A storage system
within the Enterprise Virtual Array can be formally referred to as an Enterprise storage system,
or generically referred to as the storage system.
Enterprise Virtual
Array rack A unit that holds controller enclosures, disk drive enclosures, power distribution supplies, and
enclosure address buses that, combined, comprise an Enterprise storage system solution. Also
called the Enterprise storage system rack.
See also rack.
environmental
monitoring unit See EMU.
error code The portion of an EMU condition report that defines a problem.
ESD Electrostatic Discharge. The emission of a potentially harmful static electric voltage as a result of
improper grounding.
ESI Enclosure Services Interface. The SCSI-3 engineering services interface implementation developed
for Storage products. A bus that connects the EMU to the disk drives.
ESP Enclosure Services Processor. An EMU that implements an enclosure’s services process.
event Any significant change in the state of the Enterprise storage system hardware or software
component reported by the controller to HP P6000 Command View.
See also controller event, drive enclosure event, management agent event, and termination event..
Event Information
Packet See EIP.
Event Number See Evt No.
Evt No. Event Number. A sequential number assigned to each Software Code Identification (SWCID)
event. It is a decimal number in the range 0-255.
exabyte A unit of storage capacity that is the equivalent of 2
60
bytes or 1,152,921,504,606,846,976
bytes. One exabyte is equivalent to 1,024 petabytes.
F
fabric A Fibre Channel fabric or two or more interconnected Fibre Channels allowing data transmission.
fabric port A port which is capable of supporting an attached arbitrated loop. This port on a loop will have
the AL_PA hexadecimal address 00 (loop ID 7E), giving the fabric the highest priority access to
the loop. A loop port is the gateway to the fabric for the node ports on a loop.
failover The process that takes place when one controller assumes the workload of a failed companion
controller. Failover continues until the failed controller is operational.
fan The variable speed airflow device that cools an enclosure or element by forcing ambient air into
an enclosure or element and forcing heated air out the other side.
See also blower.
Fault Management
Code See FMC.
FC HBA Fibre Channel Host Bus Adapter. An interchangeable term for Fibre Channel adapter.
See also FCA.
FCA Fibre Channel Adapter. An adapter used to connect the host server to the fabric. Also called a
Host Bus Adapter (HBA) or a Fibre Channel Host Bus Adapter (FC HBA).
See also FC HBA.
FCC Federal Communications Commission. The federal agency responsible for establishing standards
and approving electronic devices within the United States.
FCP Fibre Channel Protocol. The mapping of SCSI-3 operations to Fibre Channel.
fiber The optical media used to implement Fibre Channel.
