DH2i Company is the leading provider of server application virtualization solutions. Our products provide a unified operational model that orchestrates SQL Server management, high availability (HA), and disaster recovery (DR) across heterogeneous physical and virtual infrastructures. DxConsole and DxHADR provide individual instance mobility and policy-based monitoring, intelligently automating IT operations and maintaining required performance and availability SLAs.
SQL Server virtualization and clustering, software-defined networks, and cloud-based infrastructures were developed to help protect data and keep it available for business use. Over time, however, these SQL Server environments have become more and more complex. Read how an availability framework allows for complete application mobility between physical, virtual, or cloud infrastructures in any environment.
Every business using Microsoft SQL Server to manage mission critical business processes should have both a high availability and a disaster recovery (HADR) plan that enables it to continue business operations in the event of a natural or man-made outage. A HADR plan is different from having a backup plan...
With the release of SQL Server 2012, licensing has shifted from socket based to core based—changing requirements for unlimited virtualization. For virtualized SQL Server deployments, regardless of the project's true needs, Enterprise Edition is required. However, many of the instances being virtualized do not require any of the features of SSEE.
As organizations look to leverage SQL Server for managing mission-critical applications, minimizing lifecycle risk is a major issue. This risk exposure can take many forms. Learn how to make sure your SQL Server lifecycle management practices result in complete risk mitigation while maximizing the overall economic benefit of SQL Server throughout its lifecycle.
The technology most often considered when looking to obtain SQL Server HA is Windows Server Failover Clustering (WSFC). With WSFC, if one SQL Server database server fails in a cluster, another one will automatically take over, keeping downtime to a minimum. But WSFC has some serious limitations. Learn how to create a highly available active/active self-managed private SQL Server cloud without WSFC.
SQL Server VM sprawl has greatly increased the time and complexity of patch management, limited companies' ability to leverage physical servers for instance workloads, locked companies into a single VM vendor and created an unsustainable software license management problem.
