SES SCSI Enclosure Services. A subset of the SCSI protocol used to monitor temperature, power, and fan
status for enclosed devices.
SFP Small-form-factor pluggable. A transceiver used on 2 Gbit/sec switches that replaces the GBIC.
SilkWorm The brand name for the Brocade family of switches.
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.”
SLAP Switch Link Authentication Protocol.
SLP Service Location Protocol.
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.
SSH Secure shell. Used starting in Brocade Fabric OS v4.1 to support encrypted telnet sessions to the switch.
SSH encrypts all messages, including the client sending the password at login.
SSL Secure sockets layer.
Standard
Translative
Mode
Allows public devices to communicate with private devices that are directly connected to the fabric.
striping A RAID technique for writing a file to multiple disks on a block-by-block basis, with or without parity.
switch A fabric device providing bandwidth and high-speed routing of data via link-level addressing.
switch name The arbitrary name assigned to a switch.
switch port A port on a switch. Switch ports can be E_Ports, F_Ports, or FL_Ports.
syslog Syslog daemon. Used to forward error messages.
