Large Volume Deployment

I am asking what is the recommendation from the field  how are you deploying large volumes  ~10TB – 20 TB on Windows Host.

I understand each design will have drawbacks.  I want to see recommendations how you see this done in the field and best practices along with detailed deployment settings.  Traditionally we have tried to stay around 2-5 TB VMDK as max size VMDK on a windows host understanding the limits of current versions of ESXi Support are much larger but for backup and restore we set internal soft guidelines at around 5TB.

I know there are some legacy postings on this issue but created a new discussion board.


Thanks Everyone for thoughts!
