HP StorageWorks Fabric OS 5.0.0 MIB Reference Guide (AA-RW1QA-TE, May 2005)

288 Glossary
server
A computer that processes end-user applications or requests.
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 Gbps switches that replaces the GBIC.
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
called a 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 HP 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.
