This solution has an on-premise clouding bridge, but actively, there is no cloud version. Overall, on a scale from one to ten, I would give this solution a rating of nine. For me, it's very difficult to deal with marketing, I need to handle it for Microsoft. When we try to engage with customers, they are not interested because Microsoft doesn't have the corresponding credit, and due to this, we lose customers. If I am going to be confident enough to promote this Microsoft solution, I need my customer to have 100% trust in me. I am not comfortable promoting this solution to new customers.

Despite these challenges, online resources and clear documentation assist in the setup, enabling maintenance to be managed easily.

Scalability

Microsoft Storage Spaces Direct offers significant scalability benefits. Organizations can expand up to 16 nodes per cluster and use Cluster Sets to combine clusters. Different generations of hardware can be utilized, and storage can be increased without adding compute power. Challenges include the process of creating new volumes and migrating workloads after adding hosts. Scalability improves with more than two nodes, increasing potential while considering cluster and node configurations.

Stability

Microsoft Storage Spaces Direct experienced initial stability challenges during migration, needing thorough network configuration and training to ensure confidence. While some entities report seamless performance with Ready Nodes, others emphasize the necessity of proper management and training, noting rare incidents when running specific small applications. Lenovo Ready Nodes and properly maintained systems show heightened reliability. Users rate its stability between seven and eight, acknowledging occasional glitches.
