HPE 3PAR Cluster Extension offers protection against application downtime due to a fault, failure, or site disaster by extending a local cluster between data centers over metropolitan distance. HPE 3PAR Cluster Extension reinstates critical applications at a remote site within minutes of an adverse event, integrating your open-system clustering software and HPE 3PAR Remote Copy to automate failover and failback between sites. This dual integration enables the cluster software to verify the status of the storage and the server cluster. The cluster software can then make correct failover and failback decisions, thus minimizing downtime and accelerating recovery.
