Ceph shared filesystem (CephFS) is the primary way of storing data in nautilus and allows mounting same volumes from multiple PODs in parallel (ReadWriteMany).

Ceph block storage allows RBD (Rados Block Devices) to be attached to a single pod at a time (ReadWriteOnce). Provides fastest access to the data, and is preferred for all datasets not needing shared access from multiple pods.

UCSD NVMe CephFS filesystem policy

Warning

This policy applies to the rook-cephfs-ucsd storageclass

The filesystem is very fast and small. We expect all data on it to be used for currently running computation and then promptly deleted. We reserve the right to purge any data that's staying there longer than needed at admin's discretion without any notifications.
