F
fabric A fabric consists of cross-connected FC devices and switches.
FC Fibre Channel. High-speed serial interface technology that supports other higher layer protocols
such as SCSI and IP; FC is primarily used in SANs.
FC over Ethernet See FCoE.
FCF Fibre Channel Forwarder.
FCoE FC over Ethernet. An encapsulation of FC frames over Ethernet networks. This allows FC to use
10 Gigabit Ethernet networks while preserving the FC protocol.
FDX Full–Duplex. Allows communication to occur in both directions simultaneously.
Fibre Channel See FC.
flash Non-volatile memory where the boot code is saved. At times, flash and boot code are used
interchangeably.
frame A data unit consisting of a start-of-frame delimiter, header, data payload, CRC, and an
end-of-frame (EOF) delimiter.
FRU Field Replaceable Unit.
FTP File transfer protocol. A standard network protocol used to transfer files from one host to another
over a TCP-based network.
G
GE Gigabit Ethernet. A version of Ethernet that supports data transfer rates of 1 Gigabit per second.
H
HP mpx Manager Also known as Router Manager. A workstation-based router management tool that provides a
software interface, or a GUI, to configure and monitor intelligent storage routers.
I
IANA Internet Assigned Numbers Authority is responsible for the global coordination of the DNS root,
IP addressing, and other Internet protocol resources.
initiator A system component, such as a network interface card, that originates an I/O operation.
IOCB Input/Output Control Block.
IOCTL Input/Output Control. A system call in UNIX/Linux systems that allows an application to control
or communicate with a device driver outside usual read/write operations.
IP Internet Protocol. A method by which data is sent from one computer to another over the Internet.
IP specifies the format of packets, also called datagrams, and the addressing scheme.
IP address Internet Protocol address. The numeric address of a computer that is in the format used on the
Internet.
iqn iSCSI qualified name.
iSCSI Internet Small Computer System Interface. Transmits native SCSI over the TCP/IP stack. In a system
supporting iSCSI, a user or software application issues a command to store or retrieve data on
a SCSI storage device. The request is processed by the operating system and is converted to one
or more SCSI commands that are then passed to software or to a card. The command and data
are encapsulated by representing them as a serial string of bytes proceeded by iSCSI headers.
The encapsulated data is then passed to a TCP/IP layer that breaks it into packets suitable for
transfer over the network. If required, the encapsulated data can also be encrypted for transfer
over an insecure network.
iSNS Internet Storage Name Service. Used for discovery and management of IP-based SANs.
