It’s T-SQL Tuesday, the blog party that SQL Server expert Adam Machanic started. This month’s episode is hosted by Marlon Ribunal (blog | Twitter). The topic: That One SQL Server Outage You’ll Never Forget. As a high availability and disaster recovery expert, I’ve had a front-row seat on the outages that my customers experienced, many of them mind-boggling. But […]
I’ve had the opportunity to speak at the EightKB virtual conference and talk about a topic that I spent decades trying to learn. The goal of EightKB is to provide high value, highly technical content that focuses on what makes SQL Server work. And since my area of expertise is on high availability […]
The SQL Server Always On Failover Clustered Instance: The Senior DBA’s Ultimate Field Guide course was created in an attempt to help SQL Server DBAs and server administrators responsible for SQL Server Failover Clustered Instances (FCI) become more confident in what they do. This idea dawned on me as I was talking to customers who are unnecessarily […]
You know how it feels like to stare at this for a very long time (I ended up having to wear eyeglasses because of it.) Better yet, try it. Just for 5 minutes straight without blinking. But staring at a computer monitor for a long time isn’t the real issue. It’s the confusion of trying […]
With the continuous improvement that Microsoft has invested in the WSFC technology over the years, implementing and managing it has become a lot easier. I started doing my Gone Clustering in 60 Minutes presentation back in 2010. And I’m still amazed at how much it has improved. But I still talk about the frustrating hardware compatibility […]
In Part 2 of this blog post series, you’ve seen the interaction between SQL Server and the Windows Server Failover Cluster (WSFC). In Part 3, you’ve seen the different WSFC components that make Always On Availability Groups (AG) highly available. If SQL Server and the WSFC need to coordinate and communicate consistently to stay […]
“How can you expect to fix the engine if you don’t even know how it works?” – my friendly neighborhood car mechanic. My 20-year old Nissan X-Trail has been misbehaving recently. I can understand that, given how old it is, it has served it’s purpose. But, no. It still drives great and […]
I’ve always wanted to become a pilot ever since I was a kid. It’s one of the reasons I love traveling. I finally decided to pursue my childhood dream and scheduled an introductory flight. And it was a blast. There were preliminary lessons before we got on the plane. Not a full […]
Ever wonder what goes on under-the-hood when you deploy a SQL Server Always On Availability Groups (AGs) for high availability? I’ve been writing about AGs since it was introduced in 2012. Back when there wasn’t a lot of documentation available about the feature, we relied on direct interaction with the product team and conversations […]
I’m NOT a gamer. Nor have I played computer games as a technology professional. OK, maybe Solitaire and Minesweeper on Windows ’95. But I had the amazing opportunity to be a part of Grand Theft Auto V release back in 2013. And the not-as-popular game L.A. Noire in 2011. My colleague and […]
