For convenience and organization, the petaLibrary is split into two distinct areas. The first area, Data Commons, is for data being utilized in active research projects. This is the primary storage location where most research data is contained. The second area, Data Curation, is for data used in published research. This area is home to data that will no longer be manipulated and/or is not being used in any active research projects.

ARCC petaLibrary

petaLibrary System Overview

To provide users with a seamless computing experience, the petaLibrary is connected to the UWyo network for blazing-fast transfer speeds starting at 40 Gbps, upgradeable to 80 Gbps. The UWyo network is connected to a specialized research network at speeds of 100 Gbps to allow for high-volume bulk data transfer, remote experiment control, and data visualization.

The petaLibrary is connected to the UW network backbone at 40 Gbps (upgradeable to 80 Gbps) which is connected to the Internet2 research network at 100 Gbps so the data can be provided to the wide-area network (WAN) at world-class speeds. Connected to a specialized research network at speeds of 100 Gbps to allow for high-volume bulk data transfer, remote experiment control, and data visualization. The service is designed and operated such that access to data in the Data Commons should be limited only by the receiving endpoint or intervening network connections, not the UW infrastructure. Thus UW researchers will be able to share (and/or host) data via a service that provides world-class speeds for research data.

Storage Overview

The petaLibrary is broken down into four distinct areas: Data Commons, Data Curation (Publications, and Archive).

Data Commons

The Data Commons area is the primary storage area on petaLibrary. It is a highly collaborative space geared towards project-oriented data storage for use with multiple researchers at UWyo and beyond. To provide enhanced collaboration and control, Principal Investigators may assign access permissions to other UWyo users as well as external users.

Led by the UW/IT/Research Support group and is divided into two functional areas:


Commons is a collaborative, project-oriented storage area intended to be used jointly with other researchers (UW and/or beyond) to store data from an active research project. Principal investigators are able to delegate access permissions to other campus users or external collaborators. This area of the storage system is very similar to Bighorn on Mount Moran, but with fewer restrictions on what the system can be used for.
We anticipate making Commons available via the Shibboleth authentication system so that external collaborators may use their home credentials for access (and not have to maintain separate UW credentials). This is similar to networking services enabled with EduRoam.

Data Curation

The Data Curation area is another storage area on petaLibrary, further, split into two sub-areas. The first sub-area is called Publications. This is a space for storing and presenting research materials, data, and documentation on the Internet. All data stored here is publicly available for download, and cannot be changed once published. There is no charge for any data stored in Publications as long as it meets UWyo publication criteria. The second sub-area is called Archive. This space is called “cold storage”, meaning it contains not-published data that is no longer part of an active research project but is still valuable to the research community. Data stored in Archive may not be modified but may be retrieved or transferred to Data Commons for modifications.

Overseen by the UW Libraries, Data Curation is divided into two functional areas:


Publications are provided by the University as a service to UW researchers who, by choice or necessity, cannot publish their data in research domain-specific repositories, publisher repositories or other external repositories because suitable services don't exist or because the researcher prefers to associate UW (and their research team) as the authoritative home for the data. Publications is used to present research materials and accompanying documentation, or data on the internet. All data contained within the Publications store is publicly available for download via a UW/Libraries-provided web service and/or direct web access.
There is no charge for data stored in this repository, but it must meet publication criteria established by the UW Library and cannot be changed once published.


Archive refers to the "cold storage" portion of the petaLibrary. It will serve as a Curation repository for not-published data that is no longer part of an ongoing research project but has value to the research community.
The system will allow for retrieval of data, but will not allow for modifications to data stored within the Archive. If a change is required the data will be migrated to Data Commons until it meets the criteria for archival again.
