Handling Data

Sensitive and Protected Data
HCC currently has no storage that is suitable for HIPAA or other PID data sets. Users are not permitted to store such data on HCC machines.

All HCC machines have three separate areas for every user to store data, each intended for a different purpose. The three areas are /common, /work, and /home, each with different functions. /home is your home directory with a quota limit of 20GB and is backed up for best-effort disaster recovery purposes. /work is the high performance, I/O focused directory for running jobs. /work has a 50TB per group quote, is not backed-up and is subject to a purge policy of 6 months of inactivity on a file. /common works similarly to /work and is mounted with read and write capabilities on all HCC clusters, meaning any files on /common can be accessed from all of HCC clusters unlike /home and /work which are cluster dependant. More information on the three storage areas on HCC’s clusters are available in the Data Storage page.

HCC also offers a separate, near-line archive with space available for purchase called Attic. Attic provides reliable large data storage that is designed to be more reliable than /work, and larger than /home. More information on Attic and how to transfer data to and from Attic can be found on the Using Attic page.

You can also use your UNL Box.com account to download and upload files from any of the HCC clusters.

For moving general data into or out of HCC Resources, users are recommended to use scp for command line transfers on Windows 10, MacOS, and Linux, or for graphical transfers, WinSCP for Windows, and CyberDuck for MacOS and Linux

For moving large amounts of data into or out of HCC resources, users are highly encouraged to consider using Globus Connect.

If you have space requirements outside what is currently provided or any questions regarding moving data around, please email hcc-support@unl.edu.
