Active Peer Persistence is a feature for HPE Alletra 9000 and HPE Primera storage that keeps storage volumes (LUNs) active and accessible at both the source and target sites at the same time. It is designed to help IT teams maintain application availability when one site experiences an issue or outage.

Instead of relying on manual failover steps, Active Peer Persistence provides automatic, transparent failover. That means hosts can continue to access their data without needing to be reconfigured, even if one site goes down. In practice, it helps organizations rethink how they handle site-level disruptions by reducing downtime and operational complexity.

With Active Peer Persistence, the same LUNs are presented as active at both the source and target sites. Hosts can access these LUNs from either site, which sets the foundation for seamless failover.

When a site issue or outage occurs, the system detects the problem and automatically shifts I/O to the surviving site. This failover is designed to be transparent to the hosts, so applications continue to run without needing manual intervention or complex reconfiguration.

The video demonstration shows both the initial setup and a simulated site failure, illustrating how the storage environment continues to serve workloads from the remaining site while keeping the same LUNs active.

The setup process for Active Peer Persistence on HPE Alletra 9000 and HPE Primera involves configuring storage at both the source and target sites so that the same LUNs are active and available to hosts from each location.

In the video, the configuration steps are followed by a simulated site failure to validate behavior. During this test, workloads continue to run because the system automatically fails over to the surviving site while keeping the LUNs active. This approach helps IT teams reimagine their resilience strategy by making it easier to test and confirm that their storage environment can handle site-level disruptions without interrupting host access.
