In "About Clusters" it says:
"The hosts in a cluster all have identical hardware, run the same hypervisor, are on the same subnet, and access the same shared primary storage."

Later in the "About Hosts" it says
"May have different capacities (different CPU speeds, different amounts of RAM, etc.), although the hosts within a cluster must all be homogeneous".

The use of "identical" and "homogeneneous" to describe hardware is confusing. IMHO you don't have "identical" hardware if you have different "CPU Speeds" and "different amounts of RAM" and different "etc."

What exactly should be said about Cluster hosts? Is it sufficient to have the same CPU family?
How far can you stray in the same family?
Can a host with an AMD Opteron 6300 be in the same cluster as one based on the AMD Opteron 6200?

Is there any way to clarify these 2 sections on the same page and replace "identical" and "homogeneous" with a clearer description of what is required. The cluster comment in the Host section should probably be removed or replaced with a reference to About Clusters to avoid having duplicate and possibly conflicting information.
