How is NVMe-oF doing? Part 3: StarWind NVMe-oF Initiator + Linux SPDK NVMe-oF Target

Finally, I got the hands-on experience with StarWind NVMe-oF Initiator. I read that StarWind did a lot of work to bring NVMe-oF to Windows (it’s basically the first solution of its kind), so it’s quite interesting for me to see how their initiator works! In today’s post, I measure the performance of NVMe drive presented over Linux SPDK NVMe-oF Target while talking to it over StarWind NVMe-oF Initiator.


How is NVMe-oF doing? Part 2: Chelsio NVMe-oF Initiator + Linux SPDK NVMe-oF Target

While some OS-s built on Linux kernel support NVMe-oF, Windows just does not. No worries, there are some ways to bring this protocol to a Windows environment! In this article, I investigate whether presenting an NVMe drive over RDMA with Linux SPDK NVMe-oF Target + Chelsio NVMe-oF Initiator provides you the perfomance that vendors of flash list in their datasheets.


Re-investigating performance of SQL Server Availability Groups on Storage Spaces. Why You Should Always Enable Read-Only Routing

In this post, I am going to take a closer look at the impact of read-only routing on SQL Server Availability Groups performance.

I measured SQL Server Availability Groups (AG) performance before. And, a guy from Reddit recommended enabling read-only routing to achieve higher performance.


How is NVMe-oF doing? Part 1: Linux NVMe-oF Initiator + Linux SPDK NVMe-oF Target

Considering how often I see NVMe-related titles over the Internet, I consider NVMe-oF to be still a hot topic. That’s why I decided to pitch in 🙂


Setting up a Windows Failover Cluster for a home lab

Setting up a failover cluster is a thing that admins must do. To build such cluster, you need to configure shared storage. And, there are a lot of ways to do that. Today, I’d like to discuss how to build a Windows Failover Cluster using a virtual SAN solution (StarWind Virtual SAN) as a shared storage provider.


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?


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.
