We use Cloudera’s Distribution of Hadoop (CDH) to provide the following Hadoop services: HBase, Hive, Hue, Impala, Oozie, and Spark2, Sqoop 2, and YARN (w/ MapReduce2).

  • 20 nodes / 384 computing cores (768 threads)

STORAGE (NFS & LUSTRE)

URC provides a unified storage environment that is shared across all of the research clusters.

  • 940 TB of general user (NFS) storage space
  • 2.7 PB of InfiniBand connected Lustre distributed file system non-backed up storage space used for scratch and large volume storage needs

Each user is provided with:

  • a 500 GB home directory that is backed up for disaster recovery 
  • up to 10TB of temporary scratch storage space

Please note that quota extensions are not available for home directories or scratch space.

Scratch space is for holding temporary data needed by currently running jobs only and is not meant to hold critical data long term.  Note that scratch is not backed up and any failure will result in data loss.  DO NOT store important data in scratch.  If scratch fills, URC staff may delete older data.

Shared storage volumes in /projects and /nobackup are available for research groups upon request and must be owned by a faculty member. (Subject to available space.)

Although URC backs up some file spaces, be sure to maintain an additional copy of critical data outside the cluster.

  • Home directories have a 7-day, 4-week backup.
  • /projects have a 7-day backup.
  • /nobackup and /scratch are not backed up.

NEVER modify the permissions on your /home or /scratch directory.  If you need assistance, please contact us.


In addition to Copperhead and Cepheus, we manage and provide infrastructure support for a number of clusters that were purchased by individual faculty or research groups to meet their specific needs. These resources include:
