StandbyServer for OS/2 - Benefits of a mirroring system

Applicable to: World-Wide

Benefits of StandbyServer:
Vinca's StandbyServer mirroring system can virtually eliminate server downtime and offers the following benefits for an OS/2 LAN Server Advanced network or OS/2 application server.

Complete server fault tolerance:
Because data is mirrored to a completely separate computer, all server components are redundant. In addition, because data is mirrored to a separate computer, the Vinca solution can even recover from a software failure on the primary machine.

Primary machine and standby machine do not need to be identical:
A less expensive computer can be used as the standby machine.

Automatic switchover to the standby machine:
When the primary machine fails, the standby machine is initialized as the working server without user intervention.

Easy to install and maintain:
No complex software needs to be installed or maintained. LAN Server Advanced systems use LAN Server Advanced s built-in Fault Tolerance system, while other OS/2 systems use the easy-to-install EZRAID Lite software.

Customizable remote notification features:
Using NetFinity, Vinca's StandbyServer can notify a system administrator of a server failure at a remote workstation or even on a digital pager.

Enhanced diagnosis of server failure:
StandbyServer allows system failures to be diagnosed while users continue to have access to their data and network services.

Does not impact network traffic:
Data is mirrored through a high-speed dedicated link rather than over the network wiring. StandbyServer does not affect network traffic and in some configurations actually enhances network performance.
