Computing Carrier aims to provide high performance, high availability and easy-to-use storage service.

Tsinghua Cloud Functional Component

Carrier is a loosely coupled system consisting of five key modules: supervisors, clients, metadata servers, data servers and fuse.

Carrier is developed with Erlang & C. C is used to implement the Fuse module. With the help of the Fuse module, users can mount any folder in Carrier as a local disk driver and use it in the same way as with the other disk drivers.Files in Carrier are organized into a traditional tree structure. A file is divided into multiple 32MB chunks and stored on several data servers. Data replication and recovery are also supported in Carrier.
