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 (DxE) for AGs provides advanced fault detection and failover automation to minimize outages for SQL Server databases, helping customers achieve nearest-to-zero total downtime. The DxE for AGs tool is the only technology on the market that enables highly available SQL Server AGs 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.

Simplified Management and Networking

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 AG replication. DxE’s express-tunnels then transmit TCP payloads via UDP for superior performance and security. Watch this demo video to see how this advanced technology works together.

Using its SDP-enhanced availability group clustering technology, cross-network failover can also be achieved. This not only reduces the complexity and cost of running hybrid clusters between on-premises and the cloud, it also makes it easier to take advantage of Microsoft’s SQL Server licensing rules that allow for “free” HA and DR secondary replicas for deployments with Software Assurance.

Combine AGs with Local High Availability for Complete Business Resilience

DxE supports Extended Vhosts 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 availability groups 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-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.

Accelerate Your Enterprise’s Digital Transformation (DX) with DxEnterprise for AGs in Containers

Easily build highly available SQL Server availability groups that span multiple containers in the datacenter, remote sites and the cloud using DxEnterprise for Availability Groups in Containers. DxE for AGs in Containers enables highly available cloud-native SQL Server AGs in containers, including support for Kubernetes clusters. It simplifies the road to adopting and deploying HA stateful containers, helping organizations create new, innovative applications while accelerating their digital transformation (DX) efforts. Using its secure, multi-subnet Express Micro-Tunnel technology to automatically handle the network connectivity required for cluster communication and AG replication, creating distributed, containerized AG clusters across availability zones/regions, hybrid cloud and multi-cloud environments have never been easier.

To get started with DxEnterprise for AGs in Containers, download the free developer edition or visit the DH2i Store to purchase for production workloads.
