Abstract
Examples include a system comprising a non-volatile memory, a cluster management interface, and a multi-node cluster. In some examples, the cluster management interface may monitor a system critical alert to determine if the system critical alert has been triggered. Based on the determination that it has been triggered, the cluster management interface may multicast a system failure notification. The multi-node cluster of the system has multiple nodes, each node connected to the non-volatile memory and having a processor and a processor cache. Each node of the multi-node cluster may determine if the system failure notification has been received and based on the determination that it has been received, each node may freeze execution of all processes on the process and flush the processor cache to the non-volatile memory.
