Usage Policies at RadiaSoft

Disk Space

We divide disk space into five usage categories in order of increasing volatility:

1. /home - RAID, backed up nightly and archived permanently in two vaults
2. /var/no-archive - RAID, backed up nightly
3. /var/no-backup - RAID
4. /var/tmp - can be removed at any time
5. /tmp - cleared at boot

Our biggest constraint is on archived data. We compress the data, copy it to 2.5" disks, and take them to two separate vaults. As of 6/8/16, we are using 1TB disks, which is sufficient as long as people don't store experimental data in /home.

The general policy should be to run simulations in /var/no-archive.

Our JupyterHub partition is backed up but not archived.

CPU

On dev, don't use all the CPU. It's running production services like ownCloud and Sirepo.
