Deploying Microsoft Windows Multi-Site Failover Clusters and HPE 3PAR Peer Persistence

Executive summary

HPE 3PAR Peer Persistence software enables HPE 3PAR StoreServ systems located in different data centers at metropolitan distances to act as peers to each other, presenting nearly continuous storage system access to hosts connected to them in the event of array or data center failure. This capability allows users to configure a high-availability solution between two sites or data centers where storage access, failover, and failback remain transparent to the hosts and applications running on those hosts. Compared to traditional cluster failover models where, upon failover, the applications must be restarted, HPE 3PAR Peer Persistence software allows hosts to remain online - serving their business applications even when they switch storage access from their original site to the storage array on the remote site, resulting in a much improved recovery time.
This guide provides information about deploying Microsoft Windows Multi-Site Failover Clusters across two data centers or sites with HPE 3PAR StoreServ Peer Persistence. A Windows multi-site failover cluster is designed to maintain data availability beyond a single physical or logical site failure. Additional guidance is provided for adding a third HPE 3PAR StoreServ system to provide disaster tolerance for long distance fault boundary known as HPE 3PAR Three Data Center Peer Persistence (3DC PP).
