Storage Spaces Direct: building a fault-tolerant 4-node setup

Storage Spaces Direct picks up the baton from Microsoft Clustered Storage Spaces, meaning it is a true SDS technology for Windows Server 2016. The testing of S2D is in full swing right now, and in this research, we provide a systematic guide on a practical deployment of a fault-tolerant 4-node setup.

Enterprises seek for ultimate performance, total fault-tolerance and availability to secure their business continuity. Thus, the 4-node setup which ensures exceptional uptime even in the case of multiple node failures seems to be the right choice.

The setup consists of 9 detailed steps: from Windows Server roles and features installation to the node failure test executed with our own specialized tool called Storage Data Corruption Test.

In the result, we have successfully built an S2D 4-node setup, which can withstand a node crash. It proves to be a good example of Enterprise-level infrastructure ensuring high uptime and performance due to overprovisioning in hardware resources.

Storage Replica: Overview

Storage Replica is a feature of Windows Server 2016, designed for the disaster recovery purposes. The replication it provides is block-level and volume-based. Storage Replica is targeted at disaster avoidance since the replication of data is done to a remote location.

Before, Windows had replication only at other levels, like file-to-file replication, applications replication, and VM-level replication. There was also block-level replication in the storage market, but vendor lock-in made it too expensive.

Storage Replica provides new opportunities for disaster recovery and disaster preparedness in the industry. With it, the data is synchronously protected at two separated sites, either different buildings, cities, or countries.

Storage Replica provides synchronous and asynchronous replication. With synchronous replication, the data is written to two locations simultaneously before completion of the IO, which is a way to go for mission-critical data. Asynchronous replication provides faster response time to application, so it comes in handy when the sites are too wide apart.
