816 Glossary
S_ID Source ID. Refers to the native port address (24 bit address).
SAN Storage area network. A network of systems and storage devices that communicate using Fibre
Channel protocols. See also fabric .
SAN architecture The overall design of a storage network solution, which includes one or more related fabrics,
each of which has a topology.
SAN port count The number of ports available for connection by nodes in the entire SAN.
scalability One of the properties of a SAN: the size to which a SAN topology can grow port and switch
counts with ease.
SCC SC connector. An SC connector is a fiber-optic cable connector that uses a push-pull latching
mechanism similar to common audio and video cables. For bidirectional transmissions, two
fiber cables and two SC connectors (dual SC) are generally used. SC is specified by the TIA
as FOCIS-3.
SCN State change notification. Used for internal state change notifications, not external changes.
This is the switch logging that the port is online or is an Fx_Port, not what is sent from the
switch to the Nx_Ports.
SCSI Small Computer Systems Interface. A parallel bus architecture and a protocol for transmitting
large data blocks to a distance of 15 to 25 meters.
SCSI-2 An updated version of the SCSI bus architecture.
SCSI-3 An SCSI standard that defines transmission of SCSI protocol data over different kinds of links.
SDRAM The main memory for a switch.
sectelnet A protocol similar to telnet but with encrypted passwords for increased security.
Secure Fabric OS An optionally licensed HP feature that provides advanced, centralized security for a fabric.
security policy Rules that determine how security is implemented in a fabric. Security policies can be
customized through HP Secure Fabric OS or HP Fabric Manager.
SEQ_ID 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.
sequence A group of related frames transmitted in the same direction between two N_Ports.
sequence initiator The N_Port that begins a new sequence and transmits frames to another N_Port.
sequence recipient Serializing/deserializing circuitry. A circuit that converts a serial bit stream into parallel
characters, and vice-versa.
serial The transmission of data bits in sequential order over a single line.
server A computer that processes end-user applications or requests.
service rate The rate at which an entity can service requests. See also request rate .
SES SCSI Enclosure Services. A subset of the SCSI protocol used to monitor temperature, power,
and fan status for enclosed devices.
SFF Small-form-factor. An industry term for a smaller transceiver. See SFP .
SFP Small-form-factor pluggable. A transceiver used on 2 GB/sec switches that replaces the GBIC.
SFP cable A cable specifically designed for use with an SFP. Not compatible with GBICs.
