How many virtual machines can I put on a single Hyper-V host in a cluster?
Microsoft has increased the number to 384 virtual machines per host, with a maximum 1,000 virtual machines per cluster
. The previous number was 64, with the same maximum per cluster.
What does this mean?
- You can have 384 machines on any node in a cluster.
- You need to have capacity within the cluster so that no node has more than 384 at any given moment.
- You cannot exceed 1,000 virtual machines in a cluster.
- Continued 16 nodes per cluster
How does this affect planning?
- You still need to do appropriate consolidation planning to ensure that your virtual machines have the resources they need (esp. CPU cores, RAM, etc.)
- You will have a supported scenario for high consolidation of VDI and low utilization servers.
- Growth models should still follow a N+1 capacity pattern, regardless of whether you purchase a small number of larger host servers or a larger number of moderate host servers.
The new supported consolidation model will position Hyper-V to serve high capacity server environments, VDI, or large numbers of low utilization virtual machines. To see the official document on the topic, please see:
