Dell EMC S2D Ready Nodes are preconfigured with server and switch deployments; therefore, the information in this guide is based on the assumption that the Ready Nodes have been deployed according to the procedures in Dell EMC Microsoft Storage Spaces Direct Ready Node: Deployment guide for scalable hyper-converged infrastructure with RX740xd and R640 Storage Spaces Direct Ready Nodes.
This guide details the procedures for deploying and configuring the S2D Ready Node cluster up to virtual machine (VM) deployment. The guide also recaps some procedures that are relevant for SQL Server deployments. To support high-availability (HA) needs for any enterprise SQL Server deployment, multiple options are available at different deployment levels. For HA on a host level, we recommend Windows Host Clustering because it takes advantage of the hardware resiliency that is built into the S2D Ready Node. However, to further safeguard against operating system corruption and VM-level failures, we recommend using SQL Server clustering in conjunction with Windows Host Clustering. This guide addresses both types of clustering.
