Cloud Storage Service

Cloud Storage “creates an illusion of infinite computing resources available on demand”, thereby reducing or eliminating the need for Cloud Computing users to plan far ahead for provisioning.

Resource Pooling allows a sense of location independence in that the customer generally has no need for control or knowledge over the exact location of the provided resources but may be able to specify a location at a higher level of abstraction (e.g., country, state, or data center).
*As derived from the Red Hat Cloud Foundations Reference Architecture white paper, April 2010.

The dynamically expandable nature of the ARCC Cloud Storage allows additional capacity to be purchased in any quantity and any time, then automatically provisioned and deployed. To the customer, the available storage can appear to growth seamlessly and with minimal interruption.

Cloud Storage metering will be integrated such that resource usage can be monitored, controlled and reported transparently to the consumer.

Service Description
ARCC offers two storage avenues for Research Computing.


For users of the condo cluster and/or satellite clusters, there is a dedicated, multi-tier High Performance Storage system. See the Storage Policy for details.

Project Directory Request
To request project directory space on Bighorn, please fill out the ARCC Access Request Form.

Quota Increase
ARCC will consider reasonable requests for changes in disk space. Please fill out the disk quota section of the ARCC Access Request Form to request an storage allocation increase.


For users or projects that do not fit within the condo model an additional shared bulk storage system is available for an additional charge: UW-Bulk.  This system only supports IP connectivity via NFS/CIFS.   UW-BULK is an ISILON cluster capable of robust data protection and scalability, but is not intended for applications/workloads that have significant performance requirements
Data residing on UW-BULK will be protected with IT’s enterprise backup and recovery solution complete with offsite colocation.


  • Dynamic resource expansion
  • Standardized recovery procedures
  • Enhanced security through restricted physical access
