This document provides an overview of an IBM reference architecture for implementing high availability and disaster recovery for Microsoft SQL Server 2012 using AlwaysOn Availability Groups. The solution leverages IBM Flex System x240 compute nodes, Flex System V7000 storage, and Storwize V7000 and V3700 storage. It allows for automatic failover between two nodes in the main data center and manual failover to a node in a remote disaster recovery site, with the possibility of some data loss during asynchronous replication. The document describes the requirements, hardware components, architectural design, and deployment considerations for the solution.
