Storage is allocated by quota assigned to groups, which is shared among the users in a group. When the quota limit is reached, no more data can be written. To prevent any crises, group members will receive email notification when their group’s storage exceeds 90% of their quota limit. The notification contains a list of all the members in the group, as well as the amount of storage used by each group member. Groups nearing their quota limit can handle this issue by deleting unneeded data, or by purchasing additional storage.
Temporary storage for burst data
Some investors may run jobs that create large amounts of temporary data, which at the end of the job is deleted. Such investors have the option to request a burst allowance for their storage investment. The size of this allowance is determined by UFIT RC on a case-by-case basis, because it is dependent upon the software and workflow used by the research group.
A burst allowance gives the group the ability to exceed their normal storage investment quota for up to 30 days. Once the group exceeds their quota, they have 30 days in which to reduce their storage usage to an amount within their normal quota limit, at which point the burst allowance timer is reset. If the amount of storage used by a group has not been reduced below their quota limit after 30 days, the group will not be able to write data until fulfilling the requirement.
