Fibre Channel-
Arbitrated Loop (FC-
AL) A form of Fibre Channel network in which up to 126 nodes are
connected in a loop topology, with each node's L_Port transmitter
connecting to the L_Port receiver of the node to its logical right. Nodes
connected to a Fibre Channel Arbitrated Loop arbitrate for the single
transmission that can occur on the loop at any instant using a Fibre
Channel Arbitrated Loop protocol that is different from Fibre Channel
switched and point to point protocols. An arbitrated loop may be
private (no fabric connection) or public (attached to a fabric by an
FL_Port). (SNIA)
field-replaceable unit
(FRU) An assembly component that is designed to be replaced on site, without
the system having to be returned to the manufacturer for repair.
FRU See field-replaceable unit (FRU) .
Gbyte Gigabyte (GB).
global spare A spare disk drive that is available to all virtual disks in a system.
HBA See host bus adapter (HBA) .
host bus adapter
(HBA) An I/O adapter that connects a host I/O bus to a computer’s memory
system (SNIA).
hot swap The ability to remove and replace a FRU while the system is powered
on and operational.
in-band
management Transmission of a protocol other than the primary data protocol over
the same medium as the primary data protocol. Management protocols
are a common example of in-band transmission. (SNIA)
This type of access is available through use of the
Phoenix
Configuration API (CAPI) to develop a programmed interface.
initialization The process of writing a specific pattern to all data blocks on all disk
drives in a virtual disk. This process overwrites and destroys existing
data on the disk drives and the virtual disk. Initialization is required to
make the entire virtual disk consistent at the onset. Initialization
ensures that virtual-disk verifications performed in the future are
executed correctly.
