Hi,

you can add your host to the existing cluster, but you have to enable EVC for vMotion capabilities between different  processor technologies:

Yes, the only difference is clock speed and number of cores of those two CPUs. A best practice is to have the exact same hardware. However, that's not always possible and we allow for that flexibility. Just note that there are some implications with having dissimilar hardware. This would be a good blog - An often forgotten VMware benefit – Pick and Mix - VMware TAM Blog - VMware Blogs - as well as Duncan and Frank's HA / DRS Deepdive. You'll want to look at slot size and how having different CPU / Memory configuration within the cluster could affect HA (and potentially DRS as well): http://www.yellow-bricks.com/vmware-high-availability-deepdiv/

we havent drs license. Does it still would have no problem ?
