We have 5 new Windows (2008 R2) servers on our disposal. We plan to configure them this way:
- 3 web servers running IIS and DFS-replication (load balanced)
- 2 SQL servers running SQL server 2008 R2 in Active/Passive clustered configuration
Now, for DFS-R and clustering we need two domain controllers and we don't have enough physical servers for them.
Can Hyper-V cluster be installed on the same hardware that is running SQL cluster?
What is better:
- one node active for sql, other run virtual DCs
- each node runs it's own DC?
Possible pitfalls? Things to be careful of?
Note: I don't want to virtualize SQL servers because of the high load. DCs should not be under any load at all. Web servers don't have enough RAM for virtualization and are not connented to shared storage.
