HiPPI High-performance Parallel Interface. An 800 Mbit/sec interface normally
used in supercomputer environments.
Hop count Hop count is the number of ISLs a frame must traverse to get from its source
to its destination.
Hot swappable A component that can be replaced while under power.
HSSDC High Speed Serial Data Connection. A form factor that allows quick
connections for copper interfaces.
HSSDC-2 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 HTTPS instead of
standard HTTP links.
Hub A Fibre Channel wiring concentrator that collapses a loop topology into a
physical star topology. A hub can automatically recognize an active node and
inserts it into the loop; a node that is not functioning is automatically
removed from the loop.
Hunt Group A number of N_Ports registered as a single Alias_ID, so the fabric can route a
word to a port that is free.
I
Idle An ordered set transmitted continuously over a link when no data is being
transmitted to maintain an active link. It helps maintain bit, byte, and word
synchronization.
IFCP Internet Fibre Channel Protocol. Supports FC Layer 4 FCP-Over-TCP/IP; a
gateway-to-gateway protocol in which TCP/IP switching and routing
components exchange/replace FC fabric.
IKE Internet Key Exchange. The protocol used to set up a security association in
the IPsec protocol suite.
In-band Transmission of management protocol over the Fibre Channel transport.
Initiator A server or workstation on a Fibre Channel network that initiates
transactions to tapes or disks.
Ingress Rate Limiting A licensed fabric service that restricts the speed of traffic from a particular
device by setting the maximum speed traffic can flow through a particular
F_Port or FL_Port. See also Adaptive Networking.
Integrated Fabric The fabric created by connecting multiple Brocade switches with multiple ISL
cables, and configuring the switches to handle traffic as a seamless group.
Intercabinet A specification for copper cabling that allows up to 33-m (108 ft) distances
between cabinets.
