To utilize a DAS array as shared storage for a Windows failover cluster with block-level access, you can leverage Storage Spaces Direct (S2D) or configure the DAS as a Cluster Shared Volume (CSV). S2D creates a software-defined storage pool from the DAS drives, enabling highly available virtual disks. Alternatively, you can add the DAS as a CSV, making it accessible by all cluster nodes.
