Vote for Neverfail for VMware VirtualCenter
Neverfail for VMware VirtualCenter is a continuous availability solution designed to protect your VirtualCenter management environment, including License Server. It clones, and then continuously replicates, configuration settings, data and the SQL Server databases to ensure that a consistent, up-to-date copy of VMware VirtualCenter is maintained on a secondary server.
Neverfail then monitors VirtualCenter to predict risks to availability. Risk factors include services becoming unavailable, performance degradation, operating system failures and total machine failures. When an outage is unavoidable, Neverfail automatically switches VirtualCenter control to a secondary machine. There is no interruption to the management and control operations offered by VirtualCenter, virtual infrastructure management policies simply continue to run delivering maximum quality of service to end-user applications.
