Q: What’s the maximum size VMDK you should create in vSphere 5.1 or earlier?
File is larger than maximum file size supported (1012384)
File is larger than the maximum size supported by the datastore ‘.
|Maximum VMDK size||Maximum Overhead||Maximum size less overhead|
|256GB – 512B||~ 2GB||254GB|
|512GB – 512B||~ 4GB||508GB|
|1TB – 512B||~ 8GB||1016GB|
|2TB – 512B||~ 16GB||2032GB|
If you plan to take snapshots, the maximum VMDK size is 2032GB. Or better still, embrace Decimal, and round it off to 2000GB.
The younger generation will know a TB as 1000GB (http://en.wikipedia.org/wiki/Terabyte). Older folks will still be used to a TB being 1024GB, now known as a Tebibyte TiB (http://en.wikipedia.org/wiki/Tebibyte). Hey VMware, please update all your doco from TB to TiB 😉
