Why Upgrade to ESX 6.x? Snapshot handling! [www.vmguru.com]
A lot of organisations are still on older versions of VMware vSphere. I see ESXi deployments in the field which run on version 4.1, 5.0 and 5.5 regularly. When I ask them why they do not upgrade, I get all sorts of answers. The most common and general statement is, “I do not see any benefit in the new version”. VMware made a huge improvement to the snapshot handling and consolidation in vSphere 6.0, but they didn’t advertise this broadly to the whole community.
