It’s Time To Demystify Quorums

June 29, 2015 by sios2017 Leave a Comment

As I read through the SQL Server forums and field questions from IT pros, it surprises me how many are simply off-put by the mention of the word quorum. It’s a six-letter word treated like a part of our collective four letter vocabulary.

Quorum Defined: A voting mechanism to ensure correct ownership of cluster resources.A “quorum” in an IT-sense is simply a voting mechanism to ensure the correct ownership of a cluster. Most commonly, it’s used in conjunction with Always On (both Failover Cluster Instances and Availability Groups), Hyper-V Clusters and all Windows Server Failover Clusters.

The key isn’t to know where to use them it’s how to use them. I put together a short 30 minute webcast that dives into the a variety of quorum types most commonly used — including the pros, cons, and illustrations to demystify quorums and, dare I say, make them easy to understand. I also suggest tuning in after the 30 minute mark — we had some great questions come in as part of the Q&A.

Topic of the Evening: Turbo-Charged Transaction Logs
Presented by: David Maxwell (@dmmaxwell)

The transaction log is one of the most critical, yet often misunderstood components of SQL Server. From out of control log growth to very long startup times, problems with the transaction log can cause a lot of pain. In this session, we’ll look at how the transaction log works and how to optimize it’s performance. You’ll learn how to determine the right settings for maximum throughput, and what to do when things get out of control.
