One of the questions I was looking around as an ESX server learner, was to find out what is the difference between Persistent and Nonpersistent mode.
Normal disks are included in snapshots. In most cases, this is the setting you want ?with Independent deselected. Independant disks = no snapshots possible. The think to know is when you select Independant Disk access mode, then further you have choice between persistent and non persistent mode.
Persistent mode – is when the data is written into the disk all the time when they are modified.
Nonpersistent mode – the changes to the disk are discarded when the VM is rebooted. (good choice for a PC which is accessible to the public, which you do not want to get corrupted and polluted with all the junk from websurfing and so on…)
All this I'm able to learn from the video learning courses from TrainSignal. I don't think I would be able to learn any other way or It would cost me more money and more time….
