HP Brocade 8Gb SAN Switch for HP BladeSystem c-Class - Manual (Page 53)

directory service See SNS .
DLS Dynamic load sharing. Dynamic distribution of traffic over available paths. Allows for recomputing
of routes when an Fx_Port or E_Port changes status.
domain ID Unique identifier used in routing frames for all switches in a fabric. Usually assigned by the
principal switch, but can be assigned manually. The domain ID for an HP switch can be any
integer between 1 and 239. The default domain ID is usually 1.
E
E_D_TOV Error-detect time-out value. The minimum time a target waits for a sequence to complete before
initiating recovery. Can also be defined as the maximum time allowed for a round-trip transmission
before an error condition is declared.
E_Port Expansion port. A type of switch port that can be connected to an E_Port on another switch to
create an ISL.
EE_Credit End-to-end credit. The number of receive buffers allocated by a recipient port to an originating
port. Used by Class 1 and Class 2 services to manage the exchange of frames across the fabric
between source and destination.
EIA rack A storage rack that meets the standards set by the Electronics Industry Association (EIA)
enabled zone
configuration The currently enabled configuration of zones. Only one configuration can be enabled at a time.
end-to-end flow
control A facility that governs flow of class 1 and class 2 frames between N_Ports.
error With respect to FC, a missing or corrupted frame, time-out, loss of synchronization, or loss of
signal (link error).
exchange The highest-level FC mechanism used for communication between N_Ports. Composed of one or
more related sequences; can work in one or both directions.
F
F_Port Fabric port. A port that is able to transmit under fabric protocol and interface over links. Can be
used to connect an N_Port to a switch.
fabric An FC network containing two or more switches in addition to hosts and devices. May also be
called a switched fabric.
fabric name The unique identifier assigned to a fabric and communicated during login and port discovery.
FCIA Fibre Channel Industry Association. An international organization of FC industry professionals.
Among other things, provides oversight of ANSI and industry standards.
FCP Fibre Channel Protocol. Mapping of protocols onto the FC standard protocols. For example, SCSI
FCP maps SCSI-3 onto FC.
FCS switch Fabric Configuration Server switch. One or more designated HP switches that store and manage
the configuration and security parameters for all switches in the fabric.
Fibre Channel The primary protocol for building SANs to transmit data between servers, switches, and storage
devices. Unlike IP and Ethernet, Fibre Channel is designed to support the needs of storage devices
of all types. It is a high-speed, serial, bidirectional, topology-independent protocol, and is a highly
scalable interconnection between computers, peripherals, and networks.
fill word An IDLE or ARB ordered set that is transmitted during breaks between data frames to keep the
link active.
FL_Port Fabric loop port. A port that is able to transmit under fabric protocol and has arbitrated loop
capabilities. Can also be used to connect an NL_Port to a switch.
FLOGI The process by which an N_Port determines whether a fabric is present and, if so, exchanges
service parameters with it.
frame The Fibre Channel structure used to transmit data between ports. Consists of a start-of-frame
delimiter, header, optional headers, data payload, cyclic redundancy check, and end-of-frame
delimiter. There are two types of frames: link control frames and data frames.
