N-Shared-Disk Replicated to OneAdditional topics of interest include:• Primary Server Shutdown• Secondary Server Failures• Using DataKeeper Standard To Provide Disaster Recovery For Hyper-V Virtual Machines• Frequently Asked QuestionsN-Shared-Disk Replicated to OneThis configuration allows you to replicate the shared volume(s) of the primary site to a remote system acrossthe network.This configuration is ideal for providing local failover within the Primary Site and disaster recovery protectionshould the entire Primary Site go down.Example:USECASEExtend your MSCS or WSFC cluster to a DR site by replicating the shared volume to a remotetarget. In the event of a primary site outage, the remote server becomes the active server.Additional topics of interest include:DataKeeper for Windows Technical DocumentationPage 94
N-Shared-Disk Replicated to N-Shared-Disk• Creating Mirrors with Shared Volumes• Managing Shared Volumes• Adding a Shared System• Removing a Shared System• Frequently Asked QuestionsN-Shared-Disk Replicated to N-Shared-DiskThis configuration replicates data between sites where each site utilizes shared storage.Note that the number of systems in the Primary Site does not have to equal the number of systems in theRemote Site.Also note that only the Source Server has access to the Source Volume. Shared Source systems and allsystems on the target side cannot access the volume and are locked from the file system's perspective.Example:USECASEExample:USECASEUsers who wish to provide the same level of availability in their DR site will deploy thisconfiguration to ensure that regardless of what site is in service, the availability level stays thesame.Where Hyper-V clusters are configured with virtual machines distributed across many clusternodes, it is important to have a similar number of cluster nodes available in the disasterrecovery sight to ensure that the resources are available to run all of the virtual machines in theevent of a disaster.DataKeeper for Windows Technical DocumentationPage 95
