Failover Cluster support in Windows Server 2008 R2 with Hyper-V provides a powerful mechanism to minimize the effects of planned and unplanned server downtime. It coordinates live migrations and failover of workloads between servers through a Cluster Shared Volume (CSV). The health of the cluster depends on maintaining continuous access to the CSV and the shared disk on which it resides.
In this paper: Uninterrupted Access to Cluster Shared Volumes (CSVs) Synchronously Mirrored Across Metropolitan Hot Sites
You will learn how DataCore Software solves a longstanding stumbling block to clustered systems spread across metropolitan sites by providing uninterrupted access to the CSV despite the many technical and environmental conditions that conspire to disrupt it.
