[Berzelius-users] Berzelius downtime calendar week 4, 20th to 24th of January

[Filip Polbratt]

Dear Berzelius Users,

on Monday the 20th of January we will start a maintenance window for 
several tasks that require significant downtime of the cluster. The 
largest single task is the complete rewiring of the storage network in 
Berzelius to receive an additional 3PB of storage. We are scheduling 
this maintenance window to start on the 20th at 09:00 and to last to 
Friday the 24th, 18:00.

Jobs will not be running during this maintenance window and the login 
nodes will not be available. If you need any data that you have on 
Berzelius during this period you must access it before the maintenance 
window starts.

We might be able to return the login nodes and some compute nodes to 
service earlier. However, this should not be expected and depended upon.

Best regards,
Berzelius staff
