Shares
Chameleon provides a shared file system service through the OpenStack Manila interface. With the service, you can create a shared file system, mount to the bare metal instances, and manage some of its properties, such as visibility.
Hint
Chameleon shared file system service is currently backed by a CephFS. Same as our object store service, the data is replicated and the replication should provide good availability in case of hardware failures.
- Difference between shared file system and object store
You can choose either shared file system or object store to store, manage, and share your data with your collaborators. The object store is suitable for storing large objects at scale, but isn’t suitable for transactional data, as objects are immutable and updated in their entirety. Chameleon shared file system instead provides a NFS mount to the bare metal instances, with the NFS protocol managing locking and data integrity processes required to provide multiple concurrent access to data.
The shared file system service is available at CHI@UC and CHI@TACC. Each region has its own service and the shares created at one region are not available to the other. As all other Chameleon services, you can create and manage your shares using both GUI and CLI.
