Abstract
A method comprising managing persistent messaging data in a volatile memory of a primary instance of a multi-node server, wherein the persistent messaging data is stored in a Hard Disk Device (HDD) and a Fast Persistent Memory (FPM) of the primary instance, repeatedly replicating the persistent messaging data to a corresponding HDD and a corresponding FPM of at least one standby instance of the multi-node server, repeatedly copying the persistent messaging data stored in the FPM or the HDD of the at least one standby instance to a Recovery Memory Region (RMR) in a volatile memory of the at least one standby instance, and responsive to a failure of the primary instance, initiating a failover procedure by the standby instance, wherein the failover procedure comprises reading at least some of the persistent messaging data from the RMR in lieu of the HDD of the at least one standby instance.
