We are starting to write an LND for the BXI 3 interconnect which is under development in our labs.</div>

As discussed with Peter Jones, we will try to make it available for Lustre 2.17.</div>

Thank you for your email. This LND number is available, please submit a patch on master to reserve this number.</div>

</div>
<div>It would also be preferred to update <span style="color: rgb(16, 16, 16); font-family: Menlo; font-size: 12px; background-color: rgba(255, 255, 255, 0.87);">libcfs_netstrfns[]</span> to include the <span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">LND
name, module name, and functions to map to/from the NID string. That is fairly straight forward if addresses are numbers or IPv4/IPv6 addresses. This allows routing to/from your network even if clients/servers do not have the BXI3LND functionality.</span><br>

Our company is undergoing organizational changes so maybe there will be another company name next to "Bull".</div>

That is fine, it doesn't affect any functionality.</div>

Is it OK to reserve slot 19? Otherwise could you please indicate the next available slot number that can be reserved? </div>

Don't hesitate to contact me or Gregoire for further information,</div>
