We use IBM PowerHA SystemMirror for high availability and VM protection. It covers scenarios like local node failures or even outages across entire sites. Additionally, it can manage workloads running in a NAS environment, such as Oracle databases or applications. PowerHA operates in an active-passive mode, meaning only one node runs the workload. In case of a primary node failure, PowerHA automatically switches to the secondary node, ensuring continuous operation. If even the secondary node fails, PowerHA can further failover to another active system in a secondary site, providing an additional layer of disaster recovery.

I primarily use this solution as a database server.
