DxEnterprise for AGs

Simplified HA for SQL Server Availability Groups

Eliminate Traditional Clustering Headaches Affordably

DxEnterprise for Availability Groups (AGs) enables SQL Server AGs to be made highly available within and between Windows and Linux nodes and across any type of infrastructure—all without relying on cumbersome and restrictive cluster orchestration technologies such as Pacemaker or Windows Server Failover Clustering (WSFC). DxEnterprise for AGs provides advanced fault detection and failover automation to minimize outages for SQL Server databases, helping customers achieve nearest-to-zero total downtime. Built on patented technology, the DxE for AGs tool is the only technology on the market that enables highly available SQL Server Availability Groups across mixed Linux and Windows nodes and mixed Linux distributions. Use this inexpensive tool to make your AG deployments easier to set up and manage. Using our graphical user interface, Windows PowerShell or DxMobi, our mobile app for Android or iOS smartphones, management is intuitive and flexible.

A Hybrid Cloud Optimized for Performance and Flexibility

DxEnterprise for Availability Groups is also the easiest way to achieve a true hybrid cloud. Its built-in Smart Availability technology enables easy, dynamic movement of workloads across physical, virtual and cloud infrastructure. The cloud vendor doesn’t matter either—you can be on AWS, Azure, etc. The software enables you to move primary workloads from any cloud and easily scale cloud-based reporting nodes. DxE for AGs also allows you to offload your secondary, real-time, read-only workloads from primary databases to the cloud to scale performance and maximize flexibility. Meanwhile, all your SQL Server workloads and reporting functions remain highly available—protected by DxE for AGs’ automatic fault detection and failover capability. DxE for AGs on Linux is available in the AWS Marketplace and can be spun up in minutes.

Combine AGs with local high availability for complete business resilience

DxE supports Extended Vhosts (exVhosts) for SQL Server AGs, enabling organizations to optimize their SQL Server environment and reduce costs by as much as 50% by combining local high availability (HA) and AGs for remote data protection. ExVhosts allow SQL Server admins to create AGs that span across independent HA instances all within the same cluster, unlike typical SQL Server HA/DR environments that require separate clusters for HA instances and AGs. DxE uses Stacked-Clustering and optional Express Micro-Tunnel technology to further reduce the potential for database transaction losses, meeting near-zero RTO, and accelerate RPO by boosting SQL Server AG performance by 3x. With this advanced technology, there is no need for VPNs and SQL Server workload management is simple with easy to manage end-to-end automatic fault detection and failover. Both Windows and Linux are supported, including support for AGs across mixed OS platforms. Learn more about DxE’s support for Extended Vhosts.


Choose Your Cloud Platform

DxEnterprise for Availability groups is available both on the Microsoft Azure Marketplace and the AWS Marketplace. There are various offers for your preferred operating system as well as offers that allow you to “bring your own license” so you can customize your licensing needs.

Virtual Machine Images are available in AWS and Azure for both Windows and Linux for quick and easy deployments of DxE. DxE is also available as a VM extension in Azure for both Windows and Linux, enabling Azure customers to easily add DxE software to their VMs in just one command. Click your cloud platform of choice to access DxE offers in the marketplace.

Integrating Security into your Availability Groups



DxEnterprise for AGs integrates seamlessly with DH2i’s network security software, DxOdyssey, to make it easy to create highly available multi-server / multi-site / multi-cloud Availability Groups. Without exposing any open ports or requiring the use of a VPN, DxOdyssey automatically creates the networking tunnels between the nodes that are required for cluster communication and Availability Group replication. These Express Micro-Tunnels then transmit TCP payloads via UDP for superior performance and security.
