Overview
Centaur: XProtect Servers Failover - Standalone Failover application for Milestone Systems Management Server and SQL Server
6SS Centaur® is an application that groups two Milestone Management Servers and two SQL Servers into a virtual entity. The primary XProtect Combined server and the secondary XProtect Combined server will each have its own physical IP address. They will be combined together to form a virtual server with its own separate virtual IP address.All Milestone XProtect components, including the Event, Log, Recording, Mobile, and Microsoft SQL Servers, will be configured to use the Virtual IP Address in all their system communications. 6SS Centaur® will forward the data to the relevant server. Centaur will replicate and synchronize the real-time data once the Primary Server is down and will assure that the secondary server will take over in case the primary server goes down with minimal downtime period.
Key features
- Seamless Milestone Servers and Microsoft SQL Server Failover
