drive cage FCAL module
An interface module, located in a drive chassis,
connecting a drive cage to a controller node or
to another drive cage.
drive chassis
Enclosure that takes up 4U of an EIA-standard
rack, used for housing the drive cage(s).
drive chassis cabinet
In a multi-cabinet storage server, any cabinet
that is connected to a node cabinet but does not
contain controller nodes.
drive chassis housing
The enclosure that houses the components of a
drive chassis.
drive magazine
An electronic circuit board mounted on a
mechanical structure that is inserted into a drive
bay in a drive cage. A drive magazine holds up to
four physical disks.
drive magazine filler panel
A panel used to seal off an empty drive bay. All
slots in a drive cage must be sealed for EMI and
airflow considerations.
drive mount
A metal bracket used to secure a physical disk to
a drive magazine. Each disk requires two drive
mounts.
E
enclosure services interface
Interface on the DC2 and DC4 drive cages
through which the node software communicates
to the cage enclosure services controller to
obtain status and control the cage behaviors.
event
A normal system occurrence.
ESI
See enclosure services interface.
export
To make a virtual volume available to a
particular instance of a host (that is, a host WWN
that is actually present on a port) by creating an
association between the name of the virtual
volume and a LUN for that host on that port. See
also LUN, VLUN, and VLUN template.
F
FCAL
Stands for Fibre Channel-Arbitrated Loop. FCAL
is a fast serial bus interface standard used to
connect storage devices to servers.
FCAL module
See drive cage FCAL module.
Fibre Channel adapter
A Fibre Channel PCI host bus adapter (HBA)
located in a controller node. The Fibre Channel
adapter connects a controller node to a host or
to a drive chassis.
filtering
In the InForm Management Console, filtering a
table temporarily removes table entries that do
not meet the specified criteria. See also selecting.
G
Gigabit Ethernet adapter
A network adapter located in a controller node.
The Gigabit Ethernet adapter connects a
controller node to a network for the purpose of
