Some time ago, I published here comparison of SQL Server Failover Cluster Instances (FCI) and SQL Server Availability Group (AG) performance while having them run on top of StarWind Virtual SAN (https://www.hyper-v.io/can-sql-server-failover-cluster-instance-run-twice-fast-sql-server-basic-availability-groups-2-node-cluster-part-2-studying-fci-performance/). Today, I measure SQL Server AG performance on Storage Spaces. The next part sheds light on SQL Server FCI performance on S2D. Can I squeeze two times more TPM out of SQL Server FCI on S2D than SQL Server AG can provide on Storage Spaces?
Can SQL Server Failover Cluster Instance run on S2D twice as fast as SQL Server Availability Groups on Storage Spaces? Part 1: Studying AG performance
