HPE 3PAR Cluster Extension 6.0 (CLX) software solution provides automatic, unattended, robust disaster recovery for your mission critical workloads. 3PAR Remote Copy replication technology protects your application data by keeping a continuous, consistent copy across two 3PAR arrays, in two data centers that are several kilometers apart. Server clustering technology deployed on servers in both data centers, in stretched fashion can failover application services across the data centers. CLX software integrates the stretched cluster’s failover mechanism with 3PAR’s Remote Copy replication technology to deliver a solution that protects both your application’s data and services from disasters.

In a CLX solution, In case of disastrous outage at any of the data centers, the clustering technology performs failover of the protected applications to the surviving data center. With the help of CLX software the cluster’s failover mechanism will prepare the replicated (via 3PAR Remote Copy) application data on the target data center, before restarting the applications. There is no need for server reboots, LUN presentation / mapping changes, or any other manual intervention during disaster recovery. During a failover across data centers, the CLX solution also automatically reconfigures the replication direction, when possible to retain a resilient infrastructure all the time.

CLX solution delivers unparalleled business continuity for your mission critical workloads with their data on 3PAR arrays. The solution’s sophisticated and robust automation will allow you to meet aggressive RTO and RPO objectives, while eliminating risks associated with manual disaster recovery procedures.

CLX software is currently available for Microsoft Windows Server Enterprise platform and can be deployed in both physical and virtualized (VMware or Microsoft Hyper-V) environments. CLX integrates with Microsoft Failover Cluster's failover mechanism to provide DR automation. HPE provides support and implementation services for CLX on Microsoft Windows environment, for more information, please visit: HPE Cluster Extension Software for more information about this product.

Starting from CLX 6.0, CLX software is also available for IBM AIX. On IBM AIX , CLX integrates Power HA clustering software's failover mechanism with 3PAR Remote Copy replication.
