Release Notes

8 Configuring Dell Storage Manager for High Availability | 3272-BP-DSM
2.2.2 Microsoft Hyper-V with failover clustering
When using Hyper-V, if a host fails, the virtual machines will be restarted on another host in the cluster,
limiting downtime to how long the VMs take to reboot on another node in the cluster.
2.2.3 Live Migration
Microsoft Hyper-V Live Migration also can provide the important role of being able to proactively move the
virtual machines to another node in the cluster for maintenance. Should a host need rebooting, the virtual
machine can safely be migrated to another node in the cluster proactively.
2.2.4 Hyper-V Replica
In situations where there is no array-based storage to store the DSM VMs, a standalone Hyper-V host with
local redundant disks, in conjunction with using Hyper-V Replica, can ensure that the VMs can be recovered
on another host server or cluster in the environment. Where possible, the replicas should also be stored
outside of the failure domain of the arrays being managed.
