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.starwindsoftware.com/blog/hyper-v/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?


What is a Hyper-V Quick Create VM gallery & how to create one?

Windows 10 Creator Update introduced Quick Create to Hyper-V, the feature allowing to create a custom VM from a Hyper-V Quick Create gallery image. It is a handy tool for testing new software or OS features which developers and guys in QA may enjoy a lot. This being said, I describe today how to create a VM template and add it to a gallery.


How to create a bootable USB for Windows Server 2019 installation?

Since Windows Server 2019 release, the Internet is booming with its reviews. Someday, I maybe write my own one too. Till then, why don’t we focus on something more important than just listing new Windows Server features? In today’s post, I share the scripts for creating and formatting bootable USB disks for Windows Server.


Where is it smarter to keep databases? Azure SQL vs. Microsoft SQL Server in a VM

In this article, I compare deployment of Microsoft Azure SQL and SQL Server in a VM. I review the pros and cons of both approaches towards SQL Server deployment and take a closer look at cases when you may actually need each.


Can SQL Server Failover Cluster Instance run twice as fast as SQL Server Basic Availability Groups in 2-node cluster? Part 3: Comparison time!

In this article, I’d like to compare results of the previous two and find out whether SQL Failover Cluster Instance (FCI) can provide you two times higher performance than SQL Server Basic Availability Groups (BAG).


Can SQL Server Failover Cluster Instance run twice as fast as SQL Server Basic Availability Groups in 2-node cluster? Part 2: Studying FCI performance

In my previous article, I measured SQL Server Basic Availability Groups (BAG) performance. This, as it comes from the name, addresses SQL Cluster Failover Cluster Instance (FCI) performance. I expect SQL Server FCI to exhibit two times higher performance than BAG. Before I start, I’d like to tell you one important thing about this measurement. SQL Server FCI database resides on a StarWind virtual device. Why did I choose StarWind? Because I got their NFR license some time ago and decided to give this software-defined storage solution a shot. Let’s just hope that it won’t limit SQL Server FCI performance.


Can SQL Server Failover Cluster Instance run twice as fast as SQL Server Basic Availability Groups in 2-node cluster? Part 1: Studying BAG performance

I thought: “Hey, why not write an article about BAG performance?” Later, I realized that you need to compare this performance to something else, right? So, I decided to add SQL Server Failover Cluster Instance (FCI) performance measurements. Maybe, I’ll add some SQL Server Availability Groups (AG) measurements at the end; but, let’s see first whether SQL Server FCI can run twice as fast as SQL Server BAG. In this study, I measured BAG performance alone. Now, as we know the scope of the article, let’s move on!


Hyper-V live migrations: Which settings ensure the best performance?

This post addresses Hyper-V live migration – the topic which any admin faces with at some point. In my salad days of working as an admin, Hyper-V live migration was a saving grace, so I decided to write an article about it. In this article, I want to cover some live migration and migration wizard settings that ensure maximum performance of this process.
