RRA Layout

The following page will describe the system layout with details on where files and directories are stored.

RRA Login Nodes

When a user connects via SSH to rra.rc.usf.edu, they will end up on one of two login nodes. These are the redundant, load-balancing login nodes which will allow you to access your files, develop code, submit jobs, and review your data.

Storage

RRA has three tiers of storage, details below:

/home

/home is your primary storage location and the default location you are assigned when you log into the system.

  • 200 GB quota
  • /home resides on an encrypted BeeGFS clustered file server environment
  • Backed-up nightly

Home directories are laid out as follows:

/home/[a-z]/<netid>


where [a-z] is the first letter of the user’s NetID.

/work

/work is the scratch storage space used when running jobs. Jobs will read and write files from /work as it is designed to be fast and responsive so as not to hold up calculations. /work is

  • 2 TB quota
  • /work resides on an encrypted BeeGFS clustered file server environment
  • NOT backed up in any way
  • NOT replicated
  • Regularly purged of files that have not been accessed within 6 months.

Work directories are laid out as follows:

/work/[a-z]/<netid>


where [a-z] is the first letter of the user’s NetID.

/shares

/shares contains folders for group collaboration. If you are a member of any groups or you create any groups, you will have a folder under /shares of the same name. /shares is

  • /shares resides on an encrypted BeeGFS clustered file server environment
  • Backed-up nightly
