Glossary

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

62.5micron 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.
