[one-users] Number of KVM hosts per cluster

[Dmitri Chebotarov]

Hi

Is there a best practice for a number of KVM hosts per cluster? 

Concern I have is storage performance with large number of hosts per cluster (on system datastore).

Cluster's system datastore is on a NetApp NAS (NFS). 
I have 40 hosts. I was thinking going with 5 clusters, 8 hosts in each cluster. 
This should distribute load on storage side between 5 different volumes (5 system DS).

Does anyone have a recommendation on the subj?
