header The portion of a Fibre Channel frame that contains control and addressing
information associated with the frame.
HiPPI High-Performance Parallel Interface. An 800 Mbps interface normally used in
supercomputer environments.
hop count The number of ISLs a frame must traverse to get from its source to its destination.
host A computer system that provides end users with services, such as computation
and storage access.
hot swappable Description of a replacement unit that can be substituted for a defective unit
while the subsystem is running (performing its normal function).
HSSDC High-speed serial data connection. A form factor that allows quick connections
for copper interface.
A second-generation HSSDC connector.
HSSDC-2
See also HSSDC.
HTTP Hypertext Transfer Protocol. The standard TCP/IP transfer protocol used on
the World Wide Web.
hub A Fibre Channel wiring concentrator that collapses a loop topology into a
physical star topology. Nodes are automatically added to the loop when they
are active and removed when they are inactive.
hunt group A number of N_Ports registered as a single Alias_ID so that the fabric can
route a word to a port that is not busy.
I2C Inter-integrated circuit. A type of bus used to connect integrated circuits (ICs).
ICT Intracircuit test.
Idle Continuous transmission of an ordered set over a Fibre Channel link when no
data is being transmitted in order to keep the link active and maintain bit,
byte, and word synchronization.
ID_ID Insistent domain ID. A parameter of the configure command in Fabric OS.
iFCP Internet Fibre Channel Protocol. A protocol that supports Fibre Channel Layer 4
FCP-Over-TCP/IP. It is a gateway-to-gateway protocol in which TCP/IP switching
and routing components enhance/replace Fibre Channel fabric.
iFCS IP storage fabric configuration server.
IFL Interfabric link. A connection between a router and an edge fabric.
Architecturally, such connections can be of type EX_Port-to-E_Port or
EX_Port-to-EX_Port.
in-band Transmission of management protocol over the Fibre Channel.
initiator A server or workstation on a Fibre Channel network that initiates communications
with storage devices.
See also target.
Insistent Domain Sets the domain ID of a switch as insistent, so that it remains the same over
ID Mode reboots, power cycles, failovers, and fabric reconfigurations. This mode is
required to support FICON traffic.
See ID_ID.
integrated fabric The fabric created by an HP StorageWorks SAN Switch Integrated/64,
consisting of six HP StorageWorks 1 GB switches cabled together and
configured to handle traffic seamlessly as a group.
