PetaLibrary Storage Options and Rates
The PetaLibrary provides two primary classes of storage: "active" and "archive." Active storage may optionally be replicated to the archive infrastructure for additional resiliency at an additional cost.
The minimum size for a PetaLibrary allocation is 1 TB. Storage spaces must be ordered or renewed for at least 1 year, 1TB = 1000GB.
