Hi Helloway,
I was actually just wondering what had happened with this. Looking at the OpenStack patch it looks like it’s close to landing. Somewhere out there we have a
Cinder driver that’s also getting fairly close I believe so for sure integration with OpenStack is interesting to many in the community.
Would you be able to summarize more specifically how your patch would work once it lands? I of course see your high level description below that some questions
that I have, I’m assuming others as well, include:
- what else is required to be pushed into OpenStack for this to work
- is anything required in the SPDK repo for this to work
- how will the necessary SPDK components be associated with the VM in question and subsequently configured
Thanks for continuing to work on this!

Subject: [SPDK] Integrate OpenStack/Cyborg into SPDK Architecture
Do you know OpenStack/Cyborg? It is OpenStack acceleration service which provides a management framework for accelerator devices (e.g. FPGA, GPU, NVMe SSD). There is a strong demand for OpenStack
to support hardware accelerated devices in a dynamic model(mentioned in OpenStack Summit Vancouver 2018 [0]).
For this reason, we can use Cyborg to interactive with nvmf_tgt to realize the management of the user space accelerator NVMe SSD device, which can badly promote the efficiency. It is worth
mentioning that the Cyborg_SPDK_Driver I summitted has been merged into the OpenStack version Q [1]. The driver can report the detailed information of the device to the Cyborg agent. When user requests a vm with a user space NVMe SSD, Cyborg agent will update
the Nova/Placement inventory on available NVMe devices. This is a complete process to describe the connection of Cyborg and SPDK.
I wonder whether you guys are interested in integrating OpenStack/Cyborg into SPDK architecture? Do I make sense? Please let me know what your thoughts.
