Networking
Networking in a Hyper-V Server cluster can be very confusing for newcomers. A clustered Hyper-V Server host requires a large number of distinct network connections in comparison to most other computing system deployments. The traffic types were covered in Chapter 1, Hyper-V Cluster Orientation. For review, they are given as follows:
Management
Live Migration
Cluster and Cluster Shared Volumes
Virtual machine
Storage (unless using direct-attached)
The recommended setup is to use at least a one-gigabit adapter for each of the above. If you won't be using Cluster Shared Volumes, then you can skip having a dedicated adapter for cluster communications. The pathways to iSCSI, SMB 3.0, and Fibre Channel benefit from the redundancy of multiple adapters, and most storage can leverage multi-path I/O (MPIO) to aggregate bandwidth. Be aware that it is common to overestimate the amount of bandwidth that storage systems actually require. Keep this in mind if you are considering using more than two...
