Research Data Storage Overview

Network data storage is extremely useful for storing large amounts of data in a secure and well-supported environment. Standard research shares are stored on redundant systems, are backed up daily, and have up-to-date data snapshots. Shares are typically named based on the research project or faculty member.

Storage Space Allocation

Storage space allocations adhere to the following guidelines:

  • Shares and home directories receive a 10 GB quota by default.
  • RC offers up to 500 GB default storage for research shares by request.
  • A quota increase to 2 TB can be requested by faculty for specific research projects and is subject to review.
  • A special allocation may be available by special request only. Please email consultants@pdx.edu and include detailed information about the nature of the request and how your allocation will be used.
  • Additional storage can be purchased on an ongoing basis through OIT Computing Infrastructure Services. See the OIT-CIS service catalog for more information.

Storage System Specifications

These storage systems can be accessed directly via research account shell access, research web application, or computing and database servers:

  • NetApp high availability (HA) cluster (four 8040 nodes each with Flash Cache for improved random reads), serving both NFS and CIFS (official Microsoft licensed protocol) over 10G Ethernet, currently providing 207 TB of storage for shares (NL-SAS drives), home directories, websites and databases (SAS drives), all with Flash Pool for improved random reads and overwrites.
  • Approximately 87 TB of storage also served from NetApp HA cluster for overflow and transfer shares, though storage is front-ended older Hitachi AMS2300 via SAN.
  • Another 20 TB of storage is provided from older Hitachi AMS2300 via 8G SAN to specific research login servers.

Backups

Research shares are backed up to high-density magnetic tape, unless omission from backups are specifically requested. This ensures that data may be accessible for a number of months or years after deletion.

Daily incremental backups (with occasional “full” backups) ensure that recent research data is protected from accidental deletion. These tapes are stored off-site and rotated on a 30 day cycle. At regular intervals, some tapes are held as quarterly and yearly tape snapshots instead of being recycled.

Retrieving Backups

You can often restore a file yourself using the File Restore Tool in Windows. If this option doesn't work, you can request that OIT attempt to retrieve the file for you, by submitting the File Restore Request Form.
