Today I attended session VSP1682 ‘VMware vSphere clustering Q&A‘ hosted by Frank Denneman, Duncan Epping and Chris Colotti.
After a short introduction the Q&A started and below you will find my top 10 questions.
Q1. Are the old, vSphere 4, constraints in vSphere 5 still current?
Until vSphere 5 the best practice is a maximum of 8 hosts in a cluster, because of linked clones in VMware View and the primary/secondary ESX(i) hosts setup in an HA cluster. In vSphere 5, VMware changed this to a master/slave setup. When the master ESXi host goes offline a new master is elected within 15 sec. So, the cluster boundary limits VMware vSphere had in the past are gone. This is a huge advantage of vSphere 5.0.
