GPFS Storage Provider


(Tbugfinder) #1

Hi
few OpenNebula installations are also running HPC environments. Does OpenNebula also integrate easily with IBM Spectrum Scale (GPFS) Filesystem as a provider for either images and/or application data / scratch?

Thanks,
tb

GPFS would be supported through the shared driver, i.e. you only need to mount the volumes on the hosts.

Is it possible to use the same infiniband PCI adapter for the GPFS/rdma communication while also using PCI passthrough for it?

Not if you are using 1:1 assignment. You need a card+fw with SR-IOV support, then you can have a virtual function left on the hypervisor host for the GPFS, and separate VF(s) for use in virtual machines. Try Google for mellanox(??) IB SR-IOV keywords.
