CCR offers a wide range of storage options to suit the variety of needs and budgets of our all users.  See below for details on all we have to offer.  Please contact us to discuss your data storage needs and how we can best provide assistance for your research projects.

Vast Data Storage

The Vast Data, Inc. storage solution serves as the high reliability core storage for user home and group project directories.  The storage system consists of 2PB of usable storage in a hierarchical storage pool connected to the CCR core network with eight 40GigE links.  The storage is designed to tolerate simultaneous failures, helping ensure the 24x7x365 availability of the Center's primary storage.    

  • User home and group project directories at CCR are contained in a fault tolerant, high availability network attached storage (NAS) solution
  • CCR provides a total of 2 PB of available disk storage to all the clusters in the Center. 
  • Directories are available via NFS mounts on the clusters and accessible from all compute nodes.
  • Home directories: /user
    • Example: /user/UBIT_username/
    • Default user quota is 10GB.
    • Maximum number of files permitted per directory is 10 million.
    • Backed up by UB's Central Computing Enterprise Infrastruture Services department nightly

  • Projects directories: /projects
    • Shared directory space is available for research groups in the follow spaces:
      • Example for academic users: /projects/academic/PIUsername
      • Example for industrial users: /projects/industry/CompanyName [or projectname]
      • RPCI users:  /projects/rpci/PIusername (by agreement with RPCI this projects space is not backed up)
    • We provide UB faculty groups 1TB of space for free.
    • Maximum number of files permitted per directory is 200 million.
    • Backed up by UB's Central Computing Enterprise Infrastruture Services department nightly (note exception for /projects/rpci above).  Please note some project spaces are larger than others and may require more than 24 hours to complete a backup.  Consider keeping a separate backup of files that change frequently and are very important to you.
    • If you require more than 1TB of storage, additional space can be purchased at the current rates determined by UB's finance department:

Panasas High Speed Scratch

The 1.4 PB (petabyte) Panasas ActiveStor Ultra storage system is CCR's high performance parallel file system.   With 40GigE connections to the core Arista network, it provides I/O performance in excess of 30 GigaBytes per second sustained in tests.  Designed for high performance and concurrent access, CCR’s Panasas is primarily intended for generation and analyses of large quantities of short-lived data (scratch usage).

  • /panasas/scratch
    • Accessible from all front end servers and compute nodes via the Panasas client.
    • Available to all users for temporary use.  Find your directory based on your group or company name:
      • /panasas/scratch/grp-PIusername
      • /panasas/scratch/grp-CompanyName
    • Groups have a 10TB and a 2 million files quota.  Requests for increases to this are reviewed on a case-by-case basis.
    • Data that has not been accessed in more than 60 days is removed daily by a scrubber.  Please remove all data promptly after your job completes.
    • There is NO backup of data.

Local Scratch

All servers and compute nodes in all the clusters have local disk space (/scratch).

  • This scratch space is available to batch jobs running on the clusters.
  • Data on local scratch may be subject to removal as soon as the job completes
  • There is NO backup of data in /scratch.

UB maintains a research compute cloud, Lake Effect, available for access by UB faculty, staff, and students.  There is a small fee for usage.  In addition to access to virtual machines, users can also purchase storage in the cloud.  This storage is only accessible from servers within the cloud so it is not intended for use on the HPC clusters at CCR.  If you're looking for general cloud storage, we recommend you use UBbox, a product offered by UBIT

For more details, please check out our detailed Lake Effect knowledgebase articles.

NOTE: Data in the cloud is NOT backed up!
