header
A Fibre Channel frame has a header and a payload. The header contains control and addressing
information associated with the frame. See also payload.
HiPPI
High-Performance Parallel Interface. An 800 Mbit/sec interface normally used in supercomputer
environments.
hop count The number of ISLs a frame must traverse to get from its source to its destination. See also ISL.
host
A computer system that provides end users with services such as computation and storage access.
hot swappable A subsystem component, such as a power supply or fan assembly, that can be replaced while the overall
system remains powered and functional.
HSSDC High-speed serial data connection. A form factor that allows quick connections for copper interface.
HSSDC-2
A second-generation HSSDC connector
HTTP Hypertext Transfer Protocol. The standard TCP/IP transfer protocol used on the World Wide Web.
HTTPS
Hypertext Transfer Protocol secure link. Switches and directors configured for SSL grant access to
management tools through hypertext transfer protocol secure links (which begin with https://) instead of
standard links (which begin with http://). See also SSL.
hub
A Fibre Channel wiring concentrator that collapses a loop topology into a physical star topology. SAN
devices are automatically added to the loop when active and removed when 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.
I
I2C Related to internal circuitry on motherboard.
ID_ID
Insistent domain ID. A parameter of the configure command in the Fabric OS.
idle Continuous transmission of an ordered set over a Fibre Channel link when no data is being transmitted,
to keep the link active and maintain bit, byte, and word synchronization.
iFCP
Internet Fibre Channel Protocol. 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, these can be of type
EX_Port-to-E_Port or EX_Port-to-EX_Port.
IKE Internet Key Exchange. The protocol used to set up a security association in the IPSec protocol suite.
