(GigaBit Interface Converter) A small transceiver that plugs into the GBIC port of a network switch and connects to Fibre Channel and Gigabit Ethernet (GbE) optical fiber cables at the other end. ... The GBIC converts the serial electrical signals to serial optical signals and vice versa.

The FCID is similar to an IP address in Ethernet. It's used by Fibre Channel switches to route traffic between servers and their storage. Switches maintain a table of FCID to WWPN address mappings and what port the host is located on. The Fibre Channel switches share information with each other.

Management Data Input/Output (MDIO), also known as Serial Management Interface (SMI) or Media Independent Interface Management (MIIM), is a serial bus defined for the Ethernet family of IEEE 802.3 standards for the Media Independent Interface, or MII.

Fibre Channel is a layer 2 switching technology or cut through, with the protocol handled entirely in hardware. The iSCSI protocol (SCSI mapped to TCP/IP) running on Ethernet is a layer 3 switching technology with the protocol handled in software, hardware or some combination of the two.

PCIe Lanes: The Gist On every motherboard, there exist wires used for moving data between installed components. Those wires are called Peripheral Component Interconnect express (PCIe for short). PCIe lanes are used for many of the things you plug into your motherboard.

Layer 2, also known as the Data Link Layer, is the second level in the seven-layer OSI reference model for network protocol design. ... Layer2 is the network layer used to transfer data between adjacent network nodes in a wide area network or between nodes on the same local area network.

A gigabit represents ten to the ninth power on the International System of Units (SI). One gigabit is equal to 1,000,000,000 bits. The symbol of a gigabit is G. However, a bit is eight times smaller than a byte, which means a gigabit is eight times smaller than a gigabyte.

%GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port [dec] has bad crc. This message means that the Gigabit Interface Converter (GBIC) module is identified as a Cisco GBIC module, but it does not have a valid cyclic redundancy check (CRC) in the EEPROM data.

Most SFP+ slots are backward compatible with SFP modules to run at 1G speed. However, the SFP slots on Gigabit switch cannot support the 10G speed required by SFP+ modules. For instance, most 10Gb switches support 10G SFP+ and 1G SFP optics on SFP+ ports.

PCIe provides lower latency and higher data transfer rates than parallel busses such as PCI and PCI-X. Every device that's connected to a motherboard with a PCIe link has its own dedicated point-to-point connection. ... PCIe can scale from one to 32 separate lanes; it is usually deployed with 1, 4, 8, 12, 16 or 32 lanes.

Peripheral Component Interconnect, or PCI, is the most common way to attach add-on controller cards and other devices to a computer motherboard. This type of connector originated in the early 1990s, and is still in use today. Presently, there are three main PCI motherboard connectors (usually referred to as "slots".)

The transport layer is the fourth layer in the open system interconnection (OSI) model, and is responsible for end-to-end communication over a network. ... This layer enables the host to send and receive error corrected data, packets or messages over a network and is the network component that allows multiplexing.

GTIN describes a family of GS1 (EAN. UCC) global data structures that employ 14 digits and can be encoded into various types of data carriers. Currently, GTIN is used exclusively within bar codes, but it could also be used in other data carriers such as radio frequency identification (RFID).

GBIC and SFP are both a kind of hot-pluggable optical transceiver which is mainly used to convert between the optical signal and electrical signal. GBIC stands for Gigabit Interface Converter. SFP is short for Small Form-factor Pluggable. Usually, SFP is considered as an upgraded version of GBIC module.

IOAPIC. From OSDev Wiki. The Intel I/O Advanced Programmable Interrupt Controller is used to distribute external interrupts in a more advanced manner than that of the standard 8259 PIC. With the I/O APIC, interrupts can be distributed to physical or logical (clusters of) processors and can be prioritized.

A Gateway GPRS Support Node (GGSN) is part of the core network that connects GSM-based 3G networks to the Internet. The GGSN, sometimes known as a wireless router, works in tandem with the Serving GPRS Support Node (SGSN) to keep mobile users connected to the Internet and IP-based applications.
