Interacts with the chunkServer to read and write data 4. Snapshotcloneserver l Independent of core services l Snapshot data is stored in object storage which supports S3 apis. Therefore, there is no limit Client 1. CurveBS client provides services by libCurve. At first, external processes such as QEMU, Cinder, and NBD use it to access storage services provided by Curve. The client provids posix-like Through the above splitting, NebdClient replaces Curve Client and directly interfaces with upper services. There is no logical processing in NEBDClient, it just proxy requests and has limited retries
