SI Sequence initiative.
Simple Name Server
(SNS)
A switch service that stores names, addresses, and attributes for up to 15 minutes and
provides them as required to other devices in the fabric. SNS is defined by Fibre Channel
standards and exists at a well-known address. Also referred to as directory service or name
server.
Single CP Mode The -s option of the firmwareDownload command. Using firmwareDownload -s
enables Single CP Mode. In the 2/64, Single CP Mode enables a user to upgrade a single
CP and to select full install, autoreboot, and autocommit.
Single Mode The fiber-optic cabling standard for devices up to 10 km apart.
S-Link Service Facilities used between an N_Port and the fabric, or between two N_Ports, for login,
sequence/exchange management, and maintaining connections.
SLP Service Location Protocol.
SMDS Switched Multimegabit Data Service. A good protocol for interconnecting LANs; however,
SMDS has less error-checking capability than Frame Relay.
SMF Single-mode fiber. See LWL.
SMI Storage Management Initiative. A broad-based initiative sponsored by the Storage
Networking Industry Association (SNIA) to standardize all aspects of storage management for
multivendor storage networking products.
SMI Structure of management information. A notation for setting or retrieving SNMP management
variables.
SMI-S Storage Management Initiative Specification. Defines the interface that allows storage
management systems to manage and monitor storage area network (SAN) resources.
SNA/SDLC Systems Network Architecture/Synchronous Data Link Control. A structure for transferring data
among a variety of computing platforms.
SNMP Simple Network Management Protocol. An Internet management protocol that uses either IP
for network-level functions and UDP for transport-level functions, or TCP/IP for both. Can be
made available over other protocols, such as UDP/IP, because it does not rely on the
underlying communication protocols. See also
community (SNMP).
SNS Simple Name Server.
SOF Start of frame. A group of ordered sets that marks the beginning of a frame and indicates the
class of service the frame will use.
soft zone A zone consisting of zone members that are made visible to each other through client service
requests. Typically, soft zones contain zone members that are visible to devices using Name
Server exposure of zone members. The fabric does not enforce a soft zone. Note that
well-known addresses are implicitly included in every zone.
SoIP SCSI-over-IP.
SONET Synchronous optical network. A standard for optical networks that provides building blocks
and flexible payload mappings.
special character A 10-bit character that does not have a corresponding 8-bit value but is still considered valid.
The special character is used to indicate that a particular transmission word is an ordered set.
This is the only type of character to have five 1s or 0s in a row.
SPLD Simple PLD. Usually, either a PLA or PAL.
