HP StorageWorks Clustered File System 3.6.0 Windows Storage Server Edition Administration Guide (403103-005, January 2008)

Chapter 9: Configure PSFS Filesystems 104
There are two options:
• Static default quota. The default limits are explicitly assigned to the
user. Subsequent 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.
