Your VMware customer has a requirement for transparent failover between campus data centers. Which HP 3PAR StoreServ feature enables the customer to fulfill this requirement?

Synchronous Long Distance replication ensures data consistency between sites but does not, by itself, provide the transparent host-level failover capability required for non-disruptive operation in a metro cluster environment.

HP 3PAR Peer Persistence is a specific feature designed to enable transparent failover for VMware vSphere Metro Storage Cluster environments between two data centers. It allows host applications to maintain continuous access to data, automatically switching I/O to the secondary array in case of a primary array or site failure without application interruption.

One-to-One replication is a general description of a replication topology and does not refer to a specific HP 3PAR feature that provides transparent failover between data centers for VMware hosts.

Port Persistence is a feature that ensures host connectivity to a storage port even if its primary controller fails, operating within a single storage array, not between separate data centers.
