Glossary compact flash Volatile flash memory used in a manner similar to hard disk storage. It is connected to a bridging component that connects to the PCI bus of the processor. Not visible in the processor's memory space. Condor A Brocade 4-Gbit/sec switch and director ASIC. controlled port A port that fulfils one of the following conditions: a) is a member of an Admin Domain, either explicitly assigned or part of AD0, or b) if the switch to which the port belongs is a member of an Admin Domain. configuration (1) A set of parameters that can be modified to define the operational characteristics of a switch. (2) In Brocade Zoning, a zoning object that contains a set of zones; analogous to a zone set used by other Fibre Channel switch vendors. See also zone configuration. congestion The reduction of throughput below the requested amount either due to oversubscription within a fabric of switches or within a group of interconnected ASICs inside a switch. A congested link is an ISL on which multiple devices have collectively requested more throughput than the link supports at one time. core PID The default PID mode for SilkWorm 200E, 3016, 3250, 3850, 3900, and 4100 switches and SilkWorm directors, the recommended format for Brocade switches and fabrics. It uses the entire 8-bit address space and directly uses the port number as the area_ID. It supports up to 256 ports per switch. See also VC Encoded PID, native PID, and extended edge PID. CP1 The first-generation director CP blade provided with the SilkWorm 12000. This CP supports 1- and 2Gbit/sec port speeds. It supports only the dual domain configuration in the chassis. CP2 The second-generation director CP blade provided with the SilkWorm 24000. This CP supports 1- and 2-Gbit/sec port speeds. It supports both a dual domain and a single domain configuration in the chassis. CP4 The third-generation director CP blade provided with the SilkWorm 48000. This CP supports 1-, 2-, and 4-Gbit/sec port speeds, as well as 16-, 32-, and 48-port 4-Gbit/sec blades. It also supports the FR4-18i blade when set to chassisConfig mode 5. CRC Cyclic redundancy check. A check for transmission errors, included in every data frame. credit In Fibre Channel technology, the number of receive buffers available to transmit frames between ports. See also BB_Credit and EE_Credit. CSCN Common services connection framework. Custom zoning In EZSwitchSetup, a zoning option that provides a device accessibility matrix for you to modify and then automatically creates zones based on the matrix. See also Advanced zoning and Typical zoning. D D_ID dark fiber DAS Destination identifier. A 3-byte field in the frame header, used to indicate the address identifier of the N_Port to which the frame is headed. A leased fiber optic cable running between sites characterized by not having a service provided on the wire by the leasing company. All services are provided by the customer. Direct attached storage. 6 Brocade Glossary Publication Number: 53-1000040-03
