ESXi Thin/Flat Drive Types
Taking a VM from VMWare Workstation 7 use the vmware Converter (Downloaded from their site for free). For me, I wanted my VMs to have an expanding disk, this is how all my Workstation VMs are setup. So their limit might be 100GB, but I know I prop won’t use that and don’t want to waste the space. I want them to expand up to the 100GB when needed.
When you convert the VMs to import them into ESXi though, by default it imports the VMs with the drives set to Flat. So if you set provision to 100GB, it will make the drive 100GB on the ESXi. I found out after I’d converted, annoying. So pick Thin as seen in screenshot below and it will create an expanding disk as well. Flat gives better performance but this is just a test lab so doesn’t matter about that.
