I guess for a single use appliance this is O.K. But it makes the hardware unusable as a general purpose server. Is there a variant of the hardware to be used as a general purpose server, rather than as a Ceph appliance? If so, does it share the same DT files? > > What you are actually interested in is the sync state of the SERDES? > > The link is up if the SERDES has sync. > > yes, that's what I need. How can I do that ? Given the current code, you cannot. Now we understand the requirements, we can come up with some ideas how to do this properly. Andrew
