<div dir="ltr">I have cc'd Jake Carrol from University of Queensland in on the email as I know they have done some basic performance testing using Scale to provide storage to Openstack.</div>
<div dir="ltr">One of the issues that they found was the Openstack network translation was a performance limiting factor.</div>
<div dir="ltr"> </div>
<div dir="ltr">I think from memory the best performance scenario they had was, when they installed the scale client locally into the virtual machines</div>

<div dir="ltr">UG,
<div> </div>
<div>I have a GPFS filesystem.</div>
<div> </div>
<div>I have a OpenStack private cloud.</div>
<div> </div>
<div>What is the best way for Nova Compute VMs to have access to data inside the GPFS filesystem?</div>
<div> </div>
<div>1)Should VMs mount GPFS directly with a GPFS client?</div>
<div>2) Should the hypervisor mount GPFS and share to nova computes?</div>
<div>3) Should I create GPFS protocol servers that allow nova computes to mount of NFS?</div>
<div> </div>
<div>All advice is welcome.</div>
<div> </div>
<div> </div>
<div>Best,</div>
