Can SQL Server Failover Cluster Instance run on S2D twice as fast as SQL Server Availability Groups on Storage Spaces? Summary
Since I’m done with measuring SQL Server Basic Availability Groups (BAG) on Storage Spaces and SQL Server Failover Cluster Instances (FCI) on Storage Spaces Direct (S2D) performance, I can write the most interesting part in this series: performance comparison.
Can SQL Server Failover Cluster Instances run on S2D twice as fast as SQL Server Availability Groups on Storage Spaces? Part 2: Studying FCI performance
It is the second part of my research on SQL Server Availability Groups (AG) and SQL Server Failover Cluster Instances (FCI) performance. Before, I measured SQL Server AG performance on Storage Spaces. Today, I study the performance of SQL Server FCI on S2D, trying to prove that this thing can run 2 times faster than SQL Server AG 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
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?
So, we all know about Microsoft’s Storage Spaces Direct (S2D to put it simple) by now. It’s the feature introduced in Microsoft Server 2016 (Datacenter Edition) that pools together server’s storage allowing to build…that’s right: highly available and easily scalable software-defined storage systems. In this article, I’m gonna talk about not as much about its fault-tolerance characteristics themselves, but some hands-on experience, namely: how to replace a failed disk.
