Deploying the VMware vCenter 6.0 Appliance (VCSA) with an Embedded Platform Service Controller (PSC)

Starting with version 6, VMware has completely changed the way we deploy the vCenter server appliance (vCSA).

OK, you created your VMware cluster but the VM’s are not protected from hosts failure, and by not protected I mean your VM’s will not be automatically migrated to a working ESXi host and automatically powered on.

Creating a vSphere 5 Datastore Cluster

This is a great feature in vSphere 5 because you don’t have to keep an eye on the datastores anymore to balance the space for your VMs. Besides this Datastore Clusters minimizes I/O load on those datastores.
