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. 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.
SCN State change notification. Information the switch logs about internal (not
external) state changes, for example, a port coming online or a port being
an Fx_Port. State change notifications are not used to log information that is
sent from the switch to the Nx_Ports.
SCR State change registration. An event that occurs when the Extended Link Service
(ELS) requests that the fabric controller add the N_Port or NL_Port to the list
of N_Ports and NL_Ports registered to receive the Registered State Change
Notification (RSCN) Extended Link Service.
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 The architecture defined by the Small Computer System Interface-2 standard. An
updated version of the SCSI bus architecture.
SCSI-3 A SCSI standard that defines transmission of SCSI protocol data over different
kinds of links.
SDRAM Synchronous dynamic random access memory. The main memory for a switch.
sectelnet A protocol similar to telnet but with encrypted passwords for increased security.
Secure Fabric OS An HP StorageWorks optionally licensed 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 Secure Fabric OS or Fabric Manager.
SEQ_ID Sequence identifier. A 1-byte field in the frame header that is changed 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 The N_Port to which a particular sequence of data frames is directed.
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.

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 small transceiver.
See also SFP.
SFP Small-form-factor pluggable. A type of transceiver used on 2-Gbps and 4-Gbps
switches that replaces the GBIC.
