fabric switch

Also, switched fabric. Connects multiple devices from independent Fibre Channel-arbitrated loops (FC-ALs) and point-to-point topologies into a fabric using Fibre Channel switches.

FC

Fibre Channel is a high-speed serial inter- face technology that supports other higher layer protocols such as SCSI and IP.

FCode

Forth code. A type of boot code for use on Sun®'s SPARC® or Macintosh® hardware platforms. See also boot code and Flash.

FCoE

Fibre Channel over Ethernet. A new technology defined by the T11 standards body that allows traditional Fibre Channel storage networking traffic to travel over an Ethernet link by encapsulating Fibre Channel frames inside Layer 2 Ethernet frames. For more information, visit www.fcoe.com.

FL_Port

Fabric loop port. In a Fibre Channel, the fabric switch is capable of Fibre Channel Arbitrated Loop operations and is connected to one or more NL_Ports by a Fibre Channel Arbitrated Loop. An FL_Port becomes a shared entry point for public NL_Port devices to a Fibre Channel

fabric. FL_Ports are intermediate ports in virtual point-to-point links between end ports that do not reside on the same loop, for example NL_Port to FL_Port to F_Port to N_Port through a single Fibre Channel fabric switch.

Flash

Non-volatile memory where the boot code is saved. At times, Flash and boot code are used interchangeably.

generic port

See G_Port.

G_Port

Generic port. A port that can operate as either an E_Port or an F_Port. A G_Port can determine operating mode at switch port initialization, F_Port when an N_Port attachment is determined, E_Port when an E_Port attachment is determined. See E_Port, F_Port, FL_Port, L_Port, N_Port, NL_Port

HBA

Host bus adapter. See adapter.

input/output control

See ioctl.

intelligent storage peripheral

See ISP.

inter-switch link

See ISL.

ioctl

Input/output control. A system call in Unix/Linux systems. Allows an application to control or communicate with a device driver outside usual read/write operations.
