Hi

Vmotion does not move Virtual Machine data. It only copies the memory.

But multiple ESX hosts needs to access the same file while vmotioning.

So VMFS is the wunderkind here.

The logical volume manager (LVM) acts as a interface to the storage resources and makes the specification of the utilized hardware transparant for Virtualcenter services such as Vmotion/DRS.

VMFS acts as a cluster file system and allows multiple ESX servers to access the same files.

The VMFS layer is important for the (storage) vmotion process, not the underlying hardware.

You mentioned multiple sizes, did you configure the datastores with the same blocksize.

But I cannot think of any problems arising from using different blocksizes.

Here are the VirtualCenter VMotion Requirements

Yes, as long as both ESX Servers see the storage from both SAN or NAS devices then you can vmotion, use DRS and HA the virtual machines stored on those storage devices -

It's not an issue. I have 3 different vendors and multiple arrays per vendor going to my ESX cluster(s).
