When you use qtrees
Qtrees allow you to partition your data without incurring the overhead associated with a volume. You might create qtrees to organize your data, or to manage one or more of the following factors: quotas, security style, and CIFS oplocks setting.
The following list describes examples of qtree usage strategies:
•
Quotas
You can limit the size of the data used by a particular project, by placing all of that project's files into a qtree and applying a tree quota to the qtree.
•
Security style
If you have a project that needs to use NTFS-style security, because the members of the project use Windows files and applications, you can group the data for that project in a qtree and set its security style to NTFS, without requiring that other projects also use the same security style.
•
CIFS oplocks settings
If you have a project using a database that requires CIFS oplocks to be off, you can set CIFS oplocks to Off for that project's qtree, while allowing other projects to retain CIFS oplocks.
