Organizations typically require that their critical applications are available to end users on a continuous basis, and thus the need for reliable solutions that provide High Availability (HA) and Disaster Recovery (DR) continues to increase. Most HA and DR solutions available today use multiple redundant components to extend these vital capabilities to hosted data. Several factors are important when choosing the best and most appropriate HA and DR solutions for a given infrastructure, including reliability, robustness, cost, efficiency, automation, ease-of-use, and related performance impacts to the hosted application.
In this technical paper, we will discuss an important HA and DR feature, Microsoft SQL Server 2012 AlwaysOn Availability Groups (AVG), and how it addresses the issues mentioned above when deployed on Dell™ 12th Generation PowerEdge™ Servers. The guidelines and recommendations for implementing AVG will be illustrated by a review of some of the possible user scenarios. We will also discuss how PowerEdge Servers can be combined in a variety of server and storage configurations that make Dell the right platform for deploying Microsoft AlwaysOn HA and DR solutions.
