Router
A device connected to two or more networks that decides to which network to send
the data. It is often used in SANs to connect SCSI devices to Fibre Channel
networks.
SAN
Storage Area Network. This concept brings networking to storage. It is a highly
scalable, managed, server-storage infrastructure that offers gigabit speed data
connectivity, high system availability, extensive fault tolerance, and low cost of
ownership.
Scalability
The ability of a system to incrementally increase connectivity and performance.
SCSI
Small Computer System Interface. There are several variations that range from an
8-bit interface for up to 7 peripherals to a 16-bit interface for up to 15 peripherals.
It is commonly used for many types of peripherals such as disks, printers, scanners,
and just about anything else.
Short Wave
Lasers or LEDs that emit light with wave lengths around 780 nm or 850 nm. Short
wave lasers are used for FC-AL links up to ~700m. They are typically used with
multimode fiber. A fiber core size of 50 microns provides greater performance than
62.5 micron fiber, which is supported for compatibility with existing wiring
networks, for example, FDDI.
S_ID
A Fibre Channel Address of a frame defining the source node for that frame.
SNMP
Simple Network Management Protocol. A protocol used to examine and change
configuration parameters and counters of network-connected devices. Agents
(software running in the monitored/controlled devices) communicate with
management consoles and store variables as counters or in simple tables. The
variables are defined by MIBs.
SNMP Agent
A management entity consisting of hardware and embedded software which
responds to SNMP requests over Ethernet from an SNMP manager.
