Any other VMware version; server, player, or workstation, is not supported for production use. Those are just for demo / eval / training activities.
You can mix all SAN/iQ nodes in clusters, even multi-site, but it is not recommended that you mix types with significant performance differences (like 2060 and VSA) in the same cluster because an all 2060 cluster would perform better than a mix of 2060 and VSA. You can put them in their own clusters to do multi site with both and then you have 2 tiers of storage.
