SAN See Storage Area Network.
SAN agent A software program that
communicates with the manager and controls the
subagents. This component is largely platform
independent. See also subagent.
SAN File System SAN file systems allow
computers attached via a SAN to share data. They
typically separate the actual file data from the
metadata, using the LAN path to serve the
metadata, and the SAN path for the file data.
SAN Integration Server The SIS is a
pre-packaged system comprising an SVC, backend
storage, SAN and Ethernet Switches, and a master
controller assembled and pre-configured in a rack.
SAN Volume Controller The SVC is a SAN
appliance designed for attachment to a variety of
host computer systems, which carries out block level
virtualization of disk storage.
SCSI-3 SCSI-3 consists of a set of primary
commands and additional specialized command
sets to meet the needs of specific device types. The
SCSI-3 command sets are used not only for the
SCSI-3 parallel interface but for additional parallel
and serial protocols, including Fibre Channel, Serial
Bus Protocol (used with IEEE 1394 Firewire physical
protocol) and the Serial Storage Protocol (SSP).
SCSI Enclosure Services (SES) ANSI SCSI-3
proposal that defines a command set for soliciting
basic device status (temperature, fan speed, power
supply status, etc.) from a storage enclosures.
SCSI-FCP A standard that defines the protocol
used to transfer Small Computer System Interface
(SCSI) commands over the transport physical layer
of the fibre-channel interface. This standard is
published by ANSI as X3.269-1996.
SDD See subsystem device driver.

Serial Storage Architecture An IBM standard for
a computer peripheral interface. The interface uses
a SCSI logical protocol over a serial interface that
configures attached targets and initiators in a ring
topology
Server A program running on a mainframe,
workstation, or file server that provides shared
services. This is also referred to as a host.
Shared storage Storage within a storage facility
that is configured such that multiple homogeneous
or divergent hosts can concurrently access the
storage. The storage has a uniform appearance to
all hosts. The host programs that access the storage
must have a common model for the information on a
storage device. You need to design the programs to
handle the effects of concurrent access.
Simple Network Management Protocol A
protocol designed to give a user the capability to
remotely manage a computer network by polling and
setting terminal values and monitoring network
events.
SIS See SAN Integration Server.
Small Computer System Interface (SCSI)
ANSI standard for a logical interface to computer
peripherals and for a computer peripheral interface.
The interface utilizes a SCSI logical protocol over an
I/O interface that configures attached targets and
initiators in a multi-drop bus topology.
Small Form Factor Pluggable media (SF) a
transceiver to convert the internal electrical
communication transport to fibre gigabit transport.
For 2 Gbps fibre.
SNMP See Simple Network Management
Protocol.
