Since the nodes of a cluster must have the same hardware and software configuration, the updates will need to be installed through the "Cluster-Aware Updating (CAU)" console.

Since Windows Server 2012 R2, there is a new feature called "Dynamic witness" that allows to dynamically manage the voting right of the witness disk or share.

Configuring your cluster quorum is important for your cluster to function properly and for as long as possible.

Managing quorum and witness disk or share is very important when creating the cluster, because your cluster depends on it.

With failover clusters, you can offer many highly available services, such as file servers, iSCSI servers, DHCP servers, ...

With MPIO, you can use multiple paths to access resources of your iSCSI server and distribute the network load across multiple links.

When using multiple Hyper-V servers, it may be interesting to be able to automatically replicate some virtual machines from one server to another.

As on any virtualization server (hypervisor), you can export and import virtual machines, as well as their snapshots (checkpoints), virtual hard disks, ...

With Hyper-V, you can create virtual switches to better distribute network flows or connect virtual machines to an internal network.

Rather than using a physical hard disk from a virtual machine, you can also use an iSCSI disk as a virtual disk.

One of the main disadvantages of virtualization is the loss of performance at the storage level. Nevertheless, Hyper-V allows you to use a physical hard disk directly from a VM.

Although Hyper-V doesn't allow by default to choice the virtual hard disk's format to use, it's possible to choose it manually.
