Lenovo and Microsoft have worked closely for many years to craft a software-defined storage solution leveraging the advanced feature sets of the Windows Server and Azure Stack HCI operating systems, combined with the flexibility of Lenovo ThinkSystem rack and edge servers. In addition, we have created Lenovo ThinkAgile MX solutions that contain only servers and server components that have been certified under the Microsoft Azure Stack HCI Program to run Microsoft Storage Spaces Direct (S2D) properly.

This solution provides a solid foundation for customers looking to consolidate both storage and compute capabilities on a single hardware platform, or for those enterprises that wish to have distinct storage and compute environments. In both situations, this solution provides outstanding performance, high availability protection and effortless scale out growth potential to accommodate evolving business needs.

This deployment guide makes extensive use of Windows PowerShell commands and scripts. It guides the reader through a set of well-proven procedures leading to readiness of the solution for production use. It covers multiple deployment scenarios, including RoCE and iWARP implementations of RDMA, as well as 2- and 3-node direct-connected deployments.

If you prefer to deploy an Azure Stack HCI cluster from the Windows Admin Center (WAC) deployment wizard, please refer to our companion document at the following URL:
