VMWare block size for file server
I'm moving our file server onto virtual soon as part of a shake-up of the folder structure generally but it poses some interesting questions on how best to store the VMDK files...
We're not on vSphere 5 yet, waiting for newer version of Veeam first (and potentially an update pack for VMWare) so that means I've got the block size of the VMDK file to think about. If I do 1MB then it's max 256GB for the VMDK file, which is a bit tight as one of the shared folders I'm moving is ~200GB at the moment (splitting up the 600GB physical server into 2-3 VMs to spread the load).
Then question is whether it's worth making a store with 4MB (or even 8MB) block size when vSphere 5 is so close that can use 1MB for any datastore size you want, although that relies on waiting for the releases above and a bit of work doing the vSphere 5 update.
Any thoughts from the VMWare users on here? :)
