Thin Disk is a property (thinprovisioning) of the disk backing object of a disk device. This is only available as part of the VI3 SDK and can be seen by crawling the properties of a machine through the object browser.
Treat with care as none of the space management supports the concept and when a LUN runs out of space so does every device on it!
There are 3 SDK packages on offer:
1) VMware Infrastructure SDK Packages
2) VMware CIM SDK Packages
3) VMware Guest SDK Packages
Which one should I get? The first package?
Thanks for the help.
