High Availability and Disaster Recovery

The High Availability & Disaster Recovery Virtual Chapter focuses on one of the most important aspects of a business - data availability. The goal of the HA&DR Virtual Chapter is to provide a PASS community for Microsoft SQL Server professionals to learn more about how to protect their data and minimize the risk to a business. Join us in our monthly webinar series to learn more about the numerous tools and techniques for SQL Server business continuity. Our webinars are held on the second Tuesday of each month at 1pm Eastern. Make sure to join this Virtual Chapter in the myPASS portal so you can stay informed of our learning opportunities.

May 2017 SQL Server 2016 Always On Availability Groups Perf & Internals

Abstract

Always On Availability Groups (AGs) were introduced in SQL Server 2012. AGs significantly expanded our HA/DR options. However, in both SQL 2012 and SQL 2014 two limitations were extant in the code—both Network Transport and Log Redo significantly compromised performance. In SQL Server 2016, these limitations have been significantly improved.

 

Our work shows enhancements of 7x – 10x, allowing over 1/2GB/s (4Gb/s) across the wire. These improvements expand solutions options for Tier 1 OLTP and Data Warehouse workloads, Tier 1 and Tier 2 consolidation, and more. This presentation explains the improvements, characterizes the new solutions, and shows commodity servers and modern non-shared in-server flash storage showing the profound contrast between SQL Server 2014 vs. 2016. Doing so moves the performance bottleneck from the SQL Server codebase to the CPU where it belongs.
