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...
