S2D and SAN coexistence in Windows Server failover clustering for Hyper‑V, SQL Server, and file services
Organizations running modern data centers increasingly need flexible storage architectures that balance performance, resiliency, and investment protection. With Windows Server 2022 and Windows Server 2025, Microsoft now enables true S2D and SAN coexistence—allowing Storage Spaces Direct (S2D) to operate alongside traditional SAN storage within the same failover clustering environment. This mixed-storage approach lets IT teams optimize workloads such as Hyper-V, SQL Server, and file services by combining high-performance local storage with existing enterprise SAN infrastructure, all while maintaining full cluster support and operational consistency.
