|
| AL_PA or Arbitrated | A |
|
| Loop Physical Address | The value of the AL_PA corresponds to bits 7:0 of the |
|
|
| Address Identifier. |
|
|
|
|
|
| Arbitration | The process of selecting one respondent from a group requesting |
|
|
| service at the same time. |
|
|
|
|
|
| Close (CLS) | An Arbitrated Loop protocol used to terminate a loop circuit. |
|
|
|
|
|
| Current Fill Word | The fill word that the Loop Port State Machine uses when a fill word is to |
|
|
| be transmitted. |
|
|
|
|
|
| Duplex Cable | Two fibers in one cable suitable for duplex transmission. |
|
|
|
|
|
| Fiber Optics | Light transmission through optical fibers for communication or signaling |
|
|
|
|
|
| Fibre Channel | Fibre Channel is a data transfer interface technology that maps several |
|
|
| common transport protocols including IP and SCSI, allowing it to merge |
|
|
|
| |
|
| technology. Fibre channel is an open standard as defined by ANSI and |
|
|
| OSI standards and operates over copper and fiber optic cabling at |
|
|
| distances of up to 10 Kilometers. It is unique in its support of multiple |
|
|
| interoperable topologies including |
|
|
| switching and it offers several qualities of service for network |
|
|
| optimization. With its large packet sizes, Fibre Channel is ideal for |
|
|
| storage, video, graphic and mass data transfer applications. |
|
|
|
|
|
| LED |
| |
|
|
|
|
| Gb/s | Gigabits per second. |
|
|
|
|
|
| Node | An entity with one or more N_Ports or NL_Ports. |
|
|
|
|
|
| Open (OPN) | An Arbitrated Loop protocol used to establish a loop circuit. |
|
|
|
|
|
| Protocol | A data transmission convention which may include timing, control, |
|
|
| formatting, error detection with correction and data representation. |
|
|
|
|
|
| SCSI | Small Computer System Interface. Standard interface for storage |
|
|
| modules. |
|
|
|
|
|
| SFP | Small |
|
|
| compliant with |
|
|
| board space of the existing GBIC products. |
|
|
|
|
|
| Topology | The logical and/or physical arrangement of stations on a network. Fibre |
|
|
| Channel topologies include |
|
|
| fabric. |
|
|
|
|
|
| Transceiver | A device that converts one form of signaling to another for both |
|
|
| transmission and reception. SFPs and GBICs are transceivers. |
