Tried this with ESXi 5.0 After hours of work, we finally discovered that VMFS 5 only has the 1MB block size — but it’s been improved to allow VMDKs of up to 2TBs even with the1MB block size.

It’s funny how we adopt words and adapt our lexicon to the times. This is a very useful slant on things.

Hi Gabe,
Thanks for the great post. I figured out a way to add this into a kickstart script:

The best solution is to create two virtual disks on your RAID card. They can be in the same RAID group if needed. Make the first one 15GB and the second can consume the rest of the available space of the RAID.

Then install ESX 4 on the first 15GB virtual disk (VD / LUN). Once the install is complete and you have VIC or VCenter connected, add new storage datastore and use the 2nd VD, format it with VMFS and blocksize of your liking (Usually 4MB or 8MB).

The other beauty to this is that you can always reinstall ESX 4 anytime without disrupting your datastore with the VMs.
