4.0.0 HP Polyserve Matrix Server Administration Guide (T5392-96052, March 2010)

There are two options:
• Static default quota. The default limits are explicitly assigned to the user. Sub-
sequent changes to the default values for the filesystem do not affect the quota
limits for the user. This is the default, and matches the NTFS policy.
• Dynamic default quota. No explicit default limits are assigned to the user. Instead,
the effective limits applied to the user are the default values for the filesystem at
the time of each operation.
The File Accounting tab specifies whether real cost accounting or virtual cost
accounting should be used for sparse files.
• Real cost accounting. Sparse files are accounted against the file owner’s quota
according to the actual space used by the file (user data and metadata). This is
the default.
• Virtual cost accounting. Sparse files are accounted against the file owner’s quota
according to the entire virtual space used by the file (virtual user data and actual
metadata). This matches the NTFS policy.
