Yes, IRP supports failover mode at the operating system level. As a requirement, one must install two IRP instances on two separate hardware units having the latest CentOS operating system preinstalled. Using the CentOS High Availability feature, one of the IRP instances runs in an Active mode while the second one runs in a Passive mode. Each server must have two network cards: one used for network communication and the other one used for data synchronization with the partner instance. In case of the Active instance failure, the Passive one will immediately take over.
