Hi Anna,
To confirm -- do you mean that you are actively using just NEUTRON-STAR
and PACKAGE-FUSION, or also HECATONCHEIRES as well?
Also, did you get the email regarding the status of these servers sent
on 11/19? We're looking for a response to that from the people currently
responsible for the machines. Reproduced here:

I'm not quite sure why I had debathena@mit.edu written down as the
contact for these servers in my notes, but it looks like it wasn't the
right list to email; am I correct in thinking that we should be
contacting debathena-root@mit.edu regarding the servers instead?
In any case, we will need a confirmation of whether the servers you're
responsible for either a) continue to require UPS power, or b) could be
operated without UPS power. Just let us know which one is the case.
Also, please feel free to reach out to us at sipb-hwops@mit.edu if you
are not in COVID Pass and need to perform maintenance on any machines in
the SMR, such as to resolve the boot issue you mentioned; we are able to
provide escorted access under current MIT policies, and would be happy
to schedule a time to do so.
Thank you,
Cel Skeggs

Hi Debathena maintainers,<br>
<br>
SIPB Hardware Operations (HWOPS) is surveying the current
machines in the SMR, to determine which servers need to be on
UPS power, which servers don't need UPS power, and which servers
can be completely decommissioned and removed from the rack.<br>
<br>
As far as we can tell, NEUTRON-STAR, PACKAGE-FUSION, and
HECATONCHEIRES appear to be the current Debathena machines in
the SMR. Our current understanding is that these machines are
not used for online production services, but rather used for
building packages for Debathena, and therefore would be able to
be shut off during a power outage without causing any serious
problems. Correspondingly, we believe that they do not require
UPS power. Could you let us know whether this seems correct? If
this were the case, it would help us limit our power consumption
and reduce the budgetary impact of buying new UPSes.<br>
<br>
Thank you,<br>
Cel Skeggs<br>
