Starting April 1, 2024, new Rapid Access Service (RAS) policies will allow larger quotas for the project and nearline spaces. For more details, see the "Storage" section at [https://alliancecan.ca/en/services/advanced-research-computing/accessing-resources/rapid-access-service Rapid Access Service].  Quota changes larger than those permitted by RAS will require an application to the annual [https://alliancecan.ca/en/services/advanced-research-computing/accessing-resources/resource-allocation-competition Resource Allocation Competition (RAC)].
