Hi,

Without data protection, SX (striping across all storage targets) and S1 (using only a single storage target) are your two main options. With replication or erasure coding, there are more object classes that could be used.  The object page on github has some background:

https://github.com/daos-stack/daos/tree/release/2.0/src/object

Note that this page isn’t 100% current with the latest object layout changes in 2.0, but it’s a good starting point. We have a gap in our user documentation around this. I’m working to create some more user-level documentation around this topic right now.

Best,

Michael
