OSCER users,

REMINDER:

Scheduled maintenance outage Tue Dec 10 6am through midnight
Central Time

The Nov 26 outage reconfigured Side A;
the Dec 10 outage will reconfigure Side B.

This will affect the supercomputer, but not OURdisk, OURcloud,
nor OURRstore.

Planned maintenance tasks:

OU Facilities Management will be finishing the reconfiguration
of the power systems that feed electricity to the rows
inside of the Four Partners Place Datacenter. This work is
expected to take all of Tuesday next week. As such we are
scheduling a downtime of our systems to accommodate the
electricians to complete the work described.

The work for the project "16-25 4PP Computing Center Busbar
Feed reconfiguration" allows us to better distribute the
electrical load across the full breadth of the datacenter's
power distribution panels. This gives OSCER the ability to
have even more evenly distributed power utilization, which
gives us more available power per rack of servers.

We expect the work to start by 7am Central Time on Tuesday.
Also, we expect the work to be finished by 11:59pm Central
Time on Tuesday, that same day.

Time permitting, we'll also move a subset of scratch users from
older scratch server(s) to a new larger scratch system.
The user data will be copied to the new scratch system
in advance, so the transition is expected to be smooth.

As always, we apologize for the inconvenience -- our goal
is to make OSCER resources even better!

If you have any questions or concerns, please email us at:
