Hi Brian, For option #3, you can use GPFS Manila (OpenStack shared file system service) driver for exporting data from protocol servers to the OpenStack VMs. It was updated to support CES in the Newton release.
A new feature of bringing existing filesets under Manila management has also been added recently.

This is largely TBD but we anticipate webapps and other non-batch ways of interacting with and post processing data that has been computed on HPC batch systems. For example a user might host a website that allows users to view pieces of a large data set and do some processing in private cloud or kick off larger jobs on HPC clusters How many VM's are you running? This work is still in the design / build phase. We have 48 servers slated for the project. At max maybe 500 VMs; again this is a pretty wild estimate. This is a new service we are looking to provide What is your Network interconnect between the Scale Storage cluster and the Nova Compute cluster Each nova node has a dual 10gigE connection to switches that uplink to our core 40 gigE switches were NSD Servers are directly connectly. The information so far has been awesome. Thanks everyone. I am definitely leaning towards option #3 of creating protocol servers. Are there any design/build white papers targetting the virutalization use case?

How many VM's are you running? What is your Network interconnect between the Scale Storage cluster and the Nova Compute cluster 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. One of the issues that they found was the Openstack network translation was a performance limiting factor. I think from memory the best performance scenario they had was, when they installed the scale client locally into the virtual machines Andrew Beattie Software Defined Storage - IT Specialist Phone: 614-2133-7927 E-mail: [email protected] ----- Original message ----- From: Brian Marshall <[email protected]> Sent by: [email protected] To: gpfsug main discussion list <[email protected]> Cc: Subject: [gpfsug-discuss] Mounting GPFS data on OpenStack VM Date: Wed, Jan 18, 2017 7:51 AM UG, I have a GPFS filesystem. I have a OpenStack private cloud. What is the best way for Nova Compute VMs to have access to data inside the GPFS filesystem? 1)Should VMs mount GPFS directly with a GPFS client? 2) Should the hypervisor mount GPFS and share to nova computes? 3) Should I create GPFS protocol servers that allow nova computes to mount of NFS? All advice is welcome.
