Reference Architecture - Windows Failover Cluster - Two Nodes Multi-Site


Introduction

A two node multi-site Windows failover cluster is typically used in non-production environments. The key benefits of such an approach include providing a “cut down” replica of a standard four-node failover cluster used in production and facilitating simplified failover of services to disaster recovery sites.
In this architecture we are deploying a single Windows server in both the primary and secondary sites. These are clustered using Windows failover clustering. A quorum file server is deployed (if one does not already exist) in the primary site to provide a third “tie-breaker” node when it comes to voting on the primary node in the cluster.

Deploying A SQL 2012 AlwaysOn Cluster

This document will cover the design and deployment of a SQL Server 2012 AlwaysOn cluster. SQL Server 2012 AlwaysOn clusters are a high availability technology. They build mirrored database instances across a Windows cluster. This provides the benefits of both technologies with clustering providing a single point of access and the mirroring providing redundant copies of the databases.
