Compare High Availability Cluster Options
For high availability cluster protection for SQL Server in Windows environments, you have several options. You can use AlwaysOn Availability Groups with SQL Enterprise Edition but it will not protect distributed transactions and the number of databases protected are limited. You can use AlwaysOn Failover Clusters, but you can’t create a multi-site cluster or protect applications other than SQL. You also won’t get improved replication efficiency.
For high availability cluster and added protection, simply add SIOS DataKeeper to Microsoft SQL Server Standard Edition AlwaysOn Failover Cluster. Save thousands of dollars with Standard Edition and add the flexibility to run SQL Server in any combination of physical, virtual, or cloud environment. You can also get high availability cluster protection for applications other than SQL Server, protect distributed transactions, system databases, and improved replication efficiency.
