The Storage Spaces Direct (S2D) technology is a new feature of Windows Server 2016, available only with the Datacenter version. It requires at least 2 nodes with 2 SSDs and 4 additional disks each in order to work. The peculiarity of this system is the capability of using hosts with integrated storage (SATA, SAS or NVMe) instead of external ad-hoc solutions to realize an overall secure, scalable and high performing system. In its broader configuration, S2D can work with 16 hosts and up to 400 drives for a total storage capacity in the order of the Petabyte, with disks hot-add capability. Communication between nodes requires 10GbE network hardware with remote-direct memory access (RDMA).
