Multiple Switched Fabrics - In the Fibre Channel switched fabric topology (called FC-SW), devices are connected to each other through one or more Fibre Channel switches. Multiple switches in a fabric usually form a mesh network, with devices being on the "edges" of the mesh. OSI - The Open Systems Interconnection Basic Reference Model (OSI Reference Model or OSI Model for short). OSI is a communications and computer network protocol design that grew out a need for interoperability between equipment manufacturers. PCI - Peripheral Component Interconnect is an industry standard bus for attaching peripherals to a computer motherboard. PCS - Physical Coding Sublayer is part of the PHY, the PCS sublayer is responsible for encoding the data stream from the MAC layer for transmission by the PHY layer and decoding the data stream received from the PHY layer for the MAC layer PFC -- Priority-based Flow Control (PFC) provides a link level flow control mechanism that can be controlled for independently for each priority. The goal of this mechanism is to ensure zero loss due to congestion in DCB networks. PHY - The physical layer device, a circuit block that includes a PMD (physical media dependent), a PMA (physical media attachment), and a PCS (physical coding sublayer). PMD - Part of the PHY, the Physical-Media-Dependent sublayer is responsible for signal transmission. The typical PMD functionality includes amplifier, modulation, and wave shaping. Different PMD devices may support different media. QoS - Quality of Service is the ability to provide different priority to different applications, users, or data stream, or to ensure a certain level of performance to a data stream. RAN - Regional Area Network Serial ATA - The Serial Advanced Technology Attachment interface is primarily designed for transfer of data between a computer and mass storage devices SFP+ - 10 Gigabit Small Form Factor Pluggable transceiver module is 30% smaller, more power efficient, requires fewer components, and lower cost than the XFP form factor. SMF - Single-mode Fiber SR - Fiber cable standard for "short range" over multimode cabling TCP/IP - Transmission Control Protocol/Internet Protocol Twinax - Twinaxial cabling is a type of cable similar to coax, but with two inner conductors instead of one. Due to cost efficiency it is becoming common in modern very short range high speed differential signaling applications. UTP - Unshielded twisted pair WAN - Wide Area Network XFP - 10 Gigabit Small Form Factor Pluggable transceiver module is a hot-swappable, protocolindependent optical transceiver 15
