ESXi VM's on a SAN, multiple datastores better?

Using a  3PAR StoreServ 7200  for datastores shared by a couple of vSphere ESXi Hosts running a small number of VM's on each host.

From a performance point of view, is it better to have multiple datastores, with each VM on its own datastore rather than putting all the VM's on a single datastore?

 I'm thinking that maybe separate datastores are similar to separate hard drives and you want to divide I/O between seperate datastores to speed things up.  Does this make sense?  Or does it not work that way with datastores on a SAN?

Thanks.

But all your LUNs on your 3PAR are carved up from the same spindles.

So two datastores on the same spindles, should perform the same.

However, you may want to create multiple datastores, to split the VMs, as not to put all your eggs in one basket, should you have an issue with a single datastore, e.g. corruption etc

So it's common place to create multiple LUNs on the SAN, presented to ESXi, for multiple datastores.

We create LUNs between 500-800GB on average, and some super LUNs of 2TB for very large VMs.
