HPE 3PAR Peer Persistence software allows companies to federate their storage systems across geographically separated data centers. This inter-site federation of storage allows customers to use their data centers more effectively by allowing them to move applications from one site to another as per their business need, and more importantly, without any application downtime. Peer Persistence leverages the robust high availability solutions and extends it even further by enabling a peer relationship between storage systems located at geographically separated sites. Peer Persistence enables failover/failback between two sites/data centers to be transparent to hosts and without any disruption to applications running on them.
