I unfortunately don't have an answer other than to perhaps check out this presentation from a recent users group meeting: http://files.gpfsug.org/presentations/2017/Manchester/05_Ellexus_SSUG_Manchester.pdf<https://emea01.safelinks.protection.outlook.com/?url=http%3A%2F%2Ffiles.gpfsug.org%2Fpresentations%2F2017%2FManchester%2F05_Ellexus_SSUG_Manchester.pdf&data=01%7C01%7Cjohn.hearns%40asml.com%7C80c65bafc25d4e5a445f08d4ba15ee70%7Caf73baa8f5944eb2a39d93e96cad61fc%7C1&sdata=gIU6HVMjrqY%2BbHr%2B7EdUzcfAyDJ7WPfbFCy9Cd5%2FIHw%3D&reserved=0>

I've never used the product but it might be able to do what you're asking.

I guess this is a rather ill-defined question, and I realise it will be open to a lot of interpretations.
We have a GPFS Setup using Fujitsu filers and Mellanox infiniband.
The desire it to set up an environment for test and development where if IO ‘runs wild’ it will not bring down
the production storage. If anyone has a setup like this I would be interested in chatting with you.
Is it feasible to create filesets which have higher/lower priority than others?

Thankyou for any insights or feedback
