In ESXi 5.5, the host config has a number of similar sounding settings related to swapfiles and caches of various types.
I understand the principles of write-back/write-through disk cache and swapping VM swap files to the host instead of their remote VMDKs, and I'm reading the docs, but it's still pretty confusing which of these is which, and how they inter-relate within ESXi.
For information, my system has a single standalone host with 96GB RAM and three datastores - a local boot store, an iSCSI main store, and a 250 GB NVMe SSD for swap/cache use.
A clear explanation of the differences and how they work together would be really useful right now :)
