I've just upgraded my ESXi 6 host (single host, no clustering) from 64GB to 128GB. Prior to the upgrade I noticed my usage was around 59GB.
After upgrading, with exactly the same VM's I'm seeing usage at 119GB... I'm a little perplexed, as doing the maths shows all VM's should equate to 59GB still.
Any advice would be appreciated.
I've screenshotted the host after a restart. No VM's running and memory usage is 69GB!
Any ideas guys? - I've essentially gained very little from upgrading the RAM
