Supermicro reference architecture SYS-1028U-S2D based on 4x 1U Ultra 10 NVMe servers has received the Microsoft® Windows Server® Software-Defined (WSSD) Storage Spaces Direct(S2D) Certification, and is a part of the first wave offerings in the WSSD Solutions Catalog.Microsoft S2D solution for Windows Server 2016 targets at the cost-effective, cloud-scale software-defined data center (SDDC) market segment, allowing highly available and scalable software-defined storage (SDS) deployments on commodity x86 hardware with direct-attached storage.Microsoft S2D offers two distinct deployment options: hyper-converged and converged. Both promote a streamlined IT infrastructure with lowered CAPEX and OPEX, while delivering high scalability and flexibility, and uncompromised performance and efficiency. It is considered a direct replacement of the traditional expensive SAN infrastructure.
