SAN SAN architecture SAN port count Scalability SAS SCC SCN SCR SCSI SCSI-2 SCSI-3 SDRAM Sectelnet Secure Fabric OS Security policy SEQ_ID Sequence Sequence initiator Sequence recipient SERDES Serial Server SES Storage Area Network. A network linking computing devices to disk or tape arrays and other devices over Fibre Channel. The overall design of a storage network solution, which includes one or more related fabrics, each of which has a topology. The number of ports available for connection by nodes in the entire SAN. One of the properties of a SAN; the size to which the SAN topology can grow port and switch counts with ease. Brocade Storage Application Services. SC Connector. A fiber-optic cable connector that uses a push-pull latching mechanism similar to common audio and video cables. State Change Notification. Used for internal, not external, changes. State Change Registration. The command used by devices to register to receive RSCNs. Small Computer Systems Interface. Parallel bus architecture and a protocol for transmitting large data blocks to a distance of 15 to 25 m. An updated version of the SCSI bus architecture. A SCSI standard that defines transmission of SCSI protocol data over different kinds of links. The main memory for the switch. A protocol similar to telnet, but with encrypted passwords for increased accuracy. An optionally licensed Brocade feature that provides centralized security tools for a fabric; some Secure Fabric OS features migrated to base Fabric OS starting with Fabric OS 5.2.0 and continued in Fabric OS 5.3.0. Rules that determine how security is implemented in a fabric. Sequence Identifier; a 1-byte field in the frame header change to identify the frames as being part of a particular Exchange Sequence between a pair of ports. A group of related frames transmitted uni-directionally from one N_Port to another. The N_Port that begins a new sequence and transmits frames to another N_Port. The N_Port to which a particular sequence of data frames is directed. SERializing/DESerializing circuitry. A circuit that converts a serial bit stream into parallel characters, and vice-versa. The transmission of data bits in sequential order over a single line. A computer that processes end-user applications or requests. SCSI Enclosure Services. A subset of the SCSI protocol used to monitor temperature, power, and fan status for enclosed devices. Brocade SAN Glossary 1/29/2008 Page 24 of 29
