PRIMECLUSTER GLS for Windows User's Guide 4.3

Glossary

Activate

Refers to making a virtual adapter operational.

Adapter Setting Script

Script for assigning IP addresses in virtual adapters automatically.
This script is executed automatically after you execute the strhanet command to activate virtual adapters.

Blade Server

A server consisting of multiple computer boards ("server blades") housed together for ease of maintenance and storage. Each blade functions as an individual server.

Deactivate

Refers to making a virtual adapter unavailable for use.

Disconnect Function

A function for disconnecting failed standby adapters depending on notifications from the monitor function.

Duplicate Control Function

A function for achieving high reliability in communications by controlling the redundancy of network communication paths.

GLS

Acronym of (PRIMECLUSTER) GLS for Windows.
GLS provides software that achieves redundant line control of network transmission paths to which a system is connected, and so improves the overall reliability of the communication infrastructure.
GLS is produced by Fujitsu Ltd.

LAN

Acronym of Local Area Network.
A LAN is a network of multiple computers and other devices (such as printers) in a restricted location (such as an office).

Link Status Monitor

A function for monitoring transmission paths based on notifications of communication status between physical adapters and neighboring network devices.

MAC Address

A fixed number assigned as an identifier to an NIC.
The transfer of data between NICs is based on MAC (Media Access Control) addresses.

Monitor Function

A function for monitoring network devices connected to the server in which GLS is installed.
The monitor function sends notification to the switch function or restore function when a network failure occurs or when a network device is restored.

Network Switch

A generic name for a communications device for switching transmission paths and packet exchange.

NIC

Acronym of Network Interface Card.
A generic name for a component to connect computers and other devices to a network such as a LAN.
An NIC contains at least one network adapter for use in network communications.

NIC Sharing

A function for assigning an IP address to different network addresses by sharing NICs between virtual adapters.

NIC Switching Mode

A method of achieving high reliability in communications by duplicating network transmission paths using exclusively a pair of NICs that switch to each other when one of them has a failure. The NICs must be connected on the same network.

Operational

The status of being in use for communications, or the transmission path for these communications.
A physical adapter during operation is referred to as an "operational adapter".

Physical Adapter

A network adapter in an NIC.

Ping Monitor

A function for monitoring the communication status of the network. By setting a destination system as the ping monitor target, you can detect communication failures up to that system.
The ping monitor also sends notification to the switch function or restore function when a network failure occurs or when a network device is restored.

PRIMEQUEST

The family of IA (Intel Architecture) servers manufactured by Fujitsu Ltd.

PRIMERGY

The family of IA (Intel Architecture) servers manufactured by Fujitsu Ltd.

Restore Function

A function for connecting a physical adapter as an operational adapter or standby adapter once it has been restored after a failure.

Standby

The status of being ready to take over in case of a failure in an operational adapter, or the transmission path for that takeover.
A physical adapter during standby is referred to as a "standby adapter".

STP

Acronym of Spanning Tree Protocol.
A method of averting problems that may occur when network switches are structured as loops.

Switch Blade

A server blade equipped with a Gigabit LAN and switching hub function.

Switch Function

A function for switching communications from operational to standby adapters depending on notifications from the monitor function.

Virtual Adapter

A virtual network adapter created by bundling physical adapters.

Virtual IP Address

An IP address assigned to a virtual adapter.

Virtual MAC Address

A MAC address assigned to a virtual adapter.

VLAN Tagging

A method of attaching network-specific identifiers (called tags) to packets used when creating multiple virtual networks on the same physical line.

VLAN Tagging Adapter

A virtual adapter created with the VLAN tagging function of physical adapters.
