I’m super proud to announce that Ben E. Weissman and I have published Azure Arc-Enabled Data Services Revealed - Second Edition available now at Apress and your favorite online booksellers! Buy the book now or keep reading below if you need to be more convinced :) A couple of notes about the book first, I enjoyed working with this bleeding-edge tech and collaborating with the SQL Server Engineering Team at Microsoft on this.

At work, I get to work with some fantastic tech that pushes the boundaries of performance. I needed to do some performance testing from a Windows server into a FlashBlade using s3. I reached out to a colleague of mine, Joshua Robinson, who told me about s5cmd. s5cmd is a very fast, parallel s3 compatible command-line client. Check out Joshua’s post for some performance numbers. Here’s a direct quote from his post.

I’m proud to announce that I will be speaking at SQLBits! I had the absolute pleasure of speaking at SQLBits in the past, both in person and virtual, and experienced first hand how great this event is and cannot wait to get back and speak again (in person)! And this year, I have several sessions with some of my best friends on our data community!!! One on building and deploying container based applications in Kubernetes and the other on deploying SQL Server in Kubernetes

My updated course “Configuring and Managing Kubernetes Storage and Scheduling” is now available on Pluralsight here! If you want to learn about the course, check out the trailer here, or if you’re going to dive right in, check it out here! This course teaches you how to decouple state and configuration from your Pod’s lifecycle using persistent storage and configuration as data and how to schedule Pods to Nodes in your Kubernetes cluster.

This blog post shows you how NTFS stores data, what the NTFS Allocation Unit means, and how SQL Server performs IOs of variable size. How NTFS Stores Data on Disk A Master File Table (MFT) is the data structure that describes files and directories on NTFS. In Figure 1, you can see an MTF record has several sections describing the metadata about the file and pointers to blocks that make up the file.

In this post, we’re going to walk through configuring Active Directory authentication for SQL Server on Linux. We will start by joining the Linux server to the domain, configuring SQL Server on Linux to communicate to the domain, and then use adutil to create our AD users and set up Kerberos for SQL Server login authentication. Before getting started First, let’s get some environment requirements set. We’ll need an Active Directory domain, a Linux host to install SQL Server on, some DNS records for that host, and the DNS client on that host configured for our environment.

My updated course “Configuring and Managing Kubernetes Networking, Services, and Ingress” is now available on Pluralsight here! If you want to learn about the course, check out the trailer here, or if you’re going to dive right in, check it out here! It’s time to dig deeper into Kubernetes networking! You will learn Kubernetes cluster networking fundamentals and configuring and accessing applications in a Kubernetes Cluster with Services and Ingress.

The intent of this post is a quick reference guide based on the recommendations made on Pure Storage Support page in the Microsoft Platform Guide. The target audience for this blog post is for SQL Server DBAs introducing them to the most impactful configurations and settings for running SQL Server on physical machines on Pure Storage. Physical Host Configuration Check with your hardware vendor to see if they publish a guide for SQL Server-specific configurations for their server platforms.
