Thick vs Thin 3PAR 7450c and vSphere 5.1 Build 2323236

Hello,

I know this is tricky talk about thin and thick storage within vSphere.
Through my research I have done. The 3PAR storage creates its volumes as Thin to manage space. Which makes sense.

So, now if i create a VM within VMware with thick drives, do i gain something ? I should gain performance, right ?
What about thin ?
Or, the fact that 3PAR creates its volumes as thin, having a VM with thick vmdk's will not make any difference ?

Thanks for your help,

Take a look at the Technical paper HP 3PAR StoreServ Storage and VMware vSphere 5 best practices

Search Google for 4AA4-3286ENW

There's a good section on "HP 3PAR Thin Provisioning vs. vSphere Thin Provisioning".

Sweet, so on Page 29..

"....utilizing host-side thin provisioning reduces the underlying volume performance while at the same time incurring additional ESXi host overhead."

 

I am assuming host-side is the VMware side, right ?

Yes. Host-side is VMware side.
