If I built a virtual 2003 server with Vmware on a 2MB block size LUN, I would be limited to a 512 GB size limit. So, If I build a 100 GB server on one LUN, then build two more LUNS that are each 300 GB and map them to that server, would I be able to see the full 300 GB on each drive or would I still be limited to 512 GB.

Thanks for the help

create a new one with 8MB block size and then you will be able to create vmdk upto 2TB.

2MB = 512GB
4MB= 1024GB
8MB= 2048GB

On VMFS-3, each virtual disk is limited by the VMFS block size.  So if you have a 2MB block size, a VM could have many virtual disks, as long as each is less that 512GB is size.

VMFS-5 has no such limitation.  A virtual fisk of up to 2TB can be created on a VMFS datastore with any block size.
