Which is obviously not ideal for remote administration,<br>monitoring or getting an alert when something's wrong.<br><br>To solve that problem, we made a little shell script that does just<br>that: get inventory data, status info, and metrics like fan speeds,<br>temperatures or power usage from unmanaged Infiniband switches:<br><a href="https://github.com/stanford-rc/ibswinfo">https://github.com/stanford-rc/ibswinfo</a><br><br>It took a little reverse-engineering and a good amount of guessing,<br>but it seems to work, it fits the need, and well... it's free.
