You may know that memory page deduplication technology Transparent Page Sharing (TPS) becomes useless with large memory pages (it’s even disabled in the latest versions of VMware vSphere). However, this doesn’t mean that TPS goes into the trash bin, because when lacking resources on the host-server, ESXi may break large pages into small ones and deduplicate them afterwards. In the process, the large pages are prepared for deduplication beforehand: in case the memory workload grows up to a certain limit the large pages a broken into small ones and then, when the workload peaks, forced deduplication cycle is activated.

Rename VM network adapter automatically from Virtual Machine Manager 2016
