Double-Take how to provide extended clusters for Microsoft Hyper-V, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

February 9, 2009-Double-Take Software, the world's leading provider of workload optimization software, announced today that it is expanding its software-based replication solution, GeoCluster? To support failover clustering and Hypervisor-based virtualization in Windows Server 2008. Double-Take Software's products and services enable customers to move, protect, recover, and run workloads flexibly in both physical and virtual environments.

GeoCluster is designed to work seamlessly with failover clusters, eliminating the need for shared storage and allowing customers to easily create distributed clusters. In Hypervisor-based Window Server 2008, everything needed to support virtualization has become a feature of the operating system itself.

GeoCluster extends the clustering capabilities provided by Windows Server so that failover clusters can be established in different physical locations without sharing storage. Eliminating the need for shared storage also makes shared storage no longer the failure point of cluster applications, and improves the reliability and availability of running applications on Windows Server 2008. By extending Windows Server 2008 (Enterprise and data Center Edition) fault clustering capabilities, GeoCluster adds additional data protection, improves disaster recovery, and provides continuous data and application access between different sites.

Bob Roudebush, director of Double-Take Software Solutions Engineering, said: "GeoCluster uses Double-Take 's proven data replication capabilities to protect cluster workloads in the same simple and cost-effective way as Double-Take protects non-clustered workloads. By porting cluster capabilities to Windows Server, GeoCluster makes high availability clustering not only a local tool, but also a disaster recovery solution."

* the released GeoCluster complements the inherent failover clustering capabilities of Windows Server 2008, a cost-effective clustering software that enhances Windows Server 2008's ability to handle critical tasks and high availability Windows applications. For example, with the release of Microsoft Windows Server 2008 Hyper-V, IT managers can move virtual computers between different Hyper-V hosts through fast mobility and failover clustering features. Every licensed Windows Server 2008 Enterprise and data Center Edition has this capability, as well as extended virtualization rights. By adding GeoCluster, organizations can cluster Hyper-V workloads even if they do not have access to the storage area network. In addition, customers can not only move virtual computers within a data center, but also move virtual computers to any node in the cluster, regardless of the physical location of the node.

Zane Adam, Senior Director of Virtualization Strategy at Microsoft, said, "We have seen about 1/3 of Microsoft customers configure the clustering and high availability features of Windows Server 2008. They use server virtualization to reduce costs, including ensuring business continuity through consolidation and improved IT efficiency. Double-Take Software's GeoCluster integrates with Windows Server 2008 and Hyper-V to provide customers with a cost-effective software management solution for protecting and managing cluster applications in different physical locations.
