Ookami storage policies

There is a 0.8 Pbyte high-performance, Lustre file system, which is divided into home, project, and scratch areas. The home and project areas are backed up daily.

Home Directory

• All users on Ookami have their own home directory which is accessible only by them. The default size is 20 Gbyte, but an increase can be requested.

---

Scratch Directory

• The scratch directory has no quota, but has a policy of deleting files older than 20 days. There is a limit on the total number of files a user can create per directory. This space is NOT backed up.

---

Project Space

• Upon request from the project's PI, each project will be granted a shared (project) directory, accessible only to project members. The default is 1TB, which can be increased to multiple terabytes. Project directories larger than 5 TB will have to renew their requests annually and be prepared to move their data if space becomes limited. Large project directories may not be backed up.
