Oklahoma PetaStore

Funded by an NSF MRI grant (“Acquisition of Extensible Petascale Storage for Data Intensive Research,” OCI-1039829, $792,925, 10/01/10 - 09/30/14, PI H. Neeman), OSCER maintains an extensible petascale storage instrument – the Oklahoma PetaStore – that combines capacity for multiple Petabytes (millions of GB) of each of disk and tape, to enable faculty, staff, postdocs, graduate students and undergraduates at institutions across Oklahoma to build large and growing data collections.

The focus is on equipment into which many media (tape cartridges) can be placed, with the MRI grant funding far more slots than media, so that research teams can purchase their own media, allowing capacity to grow to multiple PB in concert with OU’s and Oklahoma’s evolving and emerging needs. The Petastore is provided to academic users at no usage charges; researchers pay for media costs only.

Please review the Petastore Policies and Procedures for information regarding usage, best practices, costs and purchase process.
