Hi Paul,
Thank you for your response, I have submitted a trello [0] titled  “Integrate OpenStack/Cyborg into SPDK Architecture”. I am trying to answer your questions from this trello, do I make sense? I really hope to receive your feedback.

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!

Hi Jim and all,

 

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.
