Abstract

This deployment guide provides comprehensive instructions for designing, deploying, and validating Microsoft Storage Spaces Direct (S2D) solutions on Lenovo ThinkAgile™ MX servers running Windows Server 2025. The document reflects the latest Microsoft and Lenovo best practices, including modern RDMA networking technologies, and certified hardware configurations.

Readers are guided through all phases of deployment, beginning with hardware preparation, firmware validation, operating system installation, and role configuration, followed by detailed deployment procedures for both converged and hyperconverged architectures. Coverage includes multiple networking models using RoCEv2 and iWARP RDMA technologies, with support for switched and direct-connected cluster designs ranging from two to sixteen nodes.

The guide emphasizes the use of Lenovo-certified ThinkAgile MX configurations validated under the Microsoft Azure Stack HCI Program, helping ensure optimal performance, resiliency, scalability, and supportability. Detailed PowerShell examples are provided throughout to streamline deployment and reduce configuration complexity.

In addition to core S2D deployment procedures, the document includes guidance for failover cluster creation, Storage Spaces Direct enablement, storage volume creation, resiliency validation, and RDMA verification for large-scale environments. The result is a practical, step-by-step reference enabling organizations to build highly available software-defined storage platforms using local server storage while eliminating the need for traditional shared-storage infrastructures.
