PowerStore Metro Volume allows a single block volume to be synchronized and active on two PowerStore appliances. This can provide additional storage resiliency for a single host or support SQL Server FCI configurations in the same or separate sites.
The most common SQL Server use case for Metro Volume is in stretch cluster or metro cluster architectures utilizing separate storage appliances. The following Microsoft example contains the high-level architecture for these scenarios with a SQL Server FCI using separate storage appliances: SQL Server Multi-Subnet Clustering – SQL Server Always On | Microsoft Learn. In this architecture, the “data replication mechanism between the sites” can be implemented with PowerStore Metro Volume.
