Ok, now that we are connecting to Sumner through SSH, we should take a minute to examine and discuss the common directory structure of the system.
/home is where the home directories for every user are kept, and are accessible by all cluster nodes. When you log in, you shold be in your /home/userid directory. Let's check that by using ssh to connect back to Sumner, and then using the pwd command we learned earlier.
ssh ssander@login.sumner.jax.org
pwd
Home directories have a quota of 50GB each, meaning that the maximum storage available to a single user's /home/userid folder is 50GB.
/projects is the primary active storage directory for users and lab groups. It is accessible by all cluster nodes. Each labgroup has a /projects/PIname-lab folder with a quota of 75TB.
/fastscratch is a temporary directory pinned to the fastest in-house storage we have available. It is accessible by all cluster nodes. It has a total capacity of 150TB, and is meant to serve as 'scratch paper' for computational analysis. Users can specify that their jobs output to /fastscratch, and then copy their important files back into their /home or /project directories. Bioinformatics software can generate a large number of temporary and intermediate files, that are often no longer needed after the analysis completes, and can accidently consume large quantities of storage. Files in the /fastscratch directory that are 10 days old will be erased automatically by the current storage system policy, and IT reserves the right to erase any and all data on /fastscratch without notice.
/gt_delivery is the delivery directory for sequence data from JAX's Genome Technologies group. It is only available via the Globus UI or command-line utility.
