+=== Lustre Quota Review ===
+Lustre quotas are adjusted at regular intervals to reflect actual usage, allowing for up to 10% over current storage consumption.
+
+For example, if your group is currently using 30 TB of a 70 TB quota, your revised allocation will be adjusted to approximately 33 TB (30 TB + 10%).
+
+For any changes to a group's existing quota, the group's Principal Investigator (PI) will receive an email notice for that change.
+
+==== Review Cadence ====
+
+Quota adjustments are performed at regular intervals depending on the quota level as follows.
+
+ * '''1 TB''': No PI group will receive less than 1 TB of storage on Lustre.
+
+ * '''8 TB or less''': For groups with 8 TB or less, reviews will be conducted annually.
+
+ * '''More than 8 TB''': For groups with allocations exceeding 8 TB, reviews will occur quarterly.
+
+We appreciate your cooperation as we continue improving the efficiency and availability of HPC resources. Please feel free to reach out with any questions or if your group's storage needs are expected to change significantly in the near term.
