Storage resources
A variety of storage resources are available in the Feig group. This page provides information on each location, its usage and backup policy, and how much space is left. Home directories
Some user home directories are located on the local disks of lab workstations. All other home directories are kept on the central NFS server blue. Home directories are fully backed up nightly. Last night's copy is accessible under /backup/<machinename> (workstation home directories) and /backup/home (home directories on blue).
Blue cluster
Additional storage is available on the nodes of the blue cluster for special projects such as the SimDB database project. This storage area is not backed up at this time.
Green cluster
The green cluster has three large RAID arrays for storage of simulation data generated on the cluster. It can be accessed from all machines in the Feig lab. Only /green/s1 is backed up weekly, but all of these storage arrays use RAID technology to prevent data loss in case of drive failures.
Orange cluster
The orange cluster houses the SimDB database. This storage location is not available for general use. It is used exclusively for simulation data.
Backups
Home directories are backed up automatically onto /backup. A secondary backup of home directories and /green/s1 is made once a week onto /feigstore.
Tape archival
A VXA-2 tape drive with 100 GB capacity is available on blue2 under /dev/st0. The easiest way to make backups is to use the tar command: tar cvf /dev/st0 <files or directory> |
