Storage Spaces Direct (S2D)

Windows Server Datacenter software-defined storage that pools local drives across cluster nodes into highly available volumes.

Definition

S2D underpins Microsoft hyperconverged infrastructure and Azure Local (formerly Azure Stack HCI), using SMB3 and RDMA between nodes. It supports 2 to 16 nodes, cache tiers and mirror or parity volumes.

Example

Enable-ClusterStorageSpacesDirect builds a pool from local NVMe and SSDs across four nodes.

Exam tip

S2D requires Datacenter edition and local (not shared SAN) drives; RDMA networking is strongly recommended.
