High Availability – Hyper-V can leverage Failover Clustering to cluster physical Hyper-V hosts together. Clustering Hyper-V hosts enables a Virtual Machine to seamlessly failover from one host to another. Highly-Available Virtual Machines are managed with Failover Cluster Manager under Roles instead of with Hyper-V Manager. Clustered VMs are usually placed on Cluster Shared Volumes (CSV) that are accessible by all nodes in the cluster. A CSV is similar to a VMFS Datastore in VMware.

Virtual Machine - A Hyper-V VM can virtualize the same basic parts as a physical computer, such as memory, processor, storage, and networking.

Disaster recovery - For disaster recovery, Hyper-V Replica creates copies of virtual machines by streaming them to another physical location, so you can restore the virtual machine from the copy.

Backup - Hyper-V offers two types of backup. A production checkpoint uses saved states and Volume Shadow Copy Service (VSS) creates application-consistent backups for programs that support VSS. Everpure has a VSS Hardware Provider that enables application consistent snapshots on the Everpure Volume.

Optimization - Each supported guest operating system has a set of services and drivers, called integration services, which allow the VM to communicate with the hypervisor.

Portability - Features such as live migration, storage migration enable migrating the VM to a new host or storage without impacting the VM availability. Import/export enables offline VM portability at the expense of time, and capacity. These features can be augmented with FlashArrays replication and snapshot technologies for a nearly instant clone of one or more VMs.

Remote connectivity - Hyper-V includes Virtual Machine Connection, which can be invoked by ‘connecting’ to a VM within Hyper-V Manager and Failover Cluster Manager. Unlike Remote Desktop, this tool gives you console access, so you can see what's happening in the guest even when the operating system isn't booted or connected to the network.

Security - Secure boot and shielded virtual machines help protect against malware and other unauthorized access to a virtual machine and its data.
