High-availability cluster

High-availability cluster is a group of computers with server application that can be reliably utilized with a minimum amount of down-time.

They operate by using high availability software to harness redundant computers in groups or clusters that provide continued service when system components fail.

Without clustering, if a server running a particular application crashes, the application will be unavailable until the crashed server is fixed.

HA clustering remedies this situation by detecting hardware/software faults, and immediately restarting the application on another system without requiring administrative intervention, a process known as failover. As part of this process, clustering software may configure the node before starting the application on it.

For achieving high availability of resourses Supplier in SONM may organize high-availability cluster with three of more Hub nodes using the following software:
