The Corsair file system(CorsairFS)

a scalable distributed file system for data sharing and online storage in campus network or intranet

is proposed.Adopting scalable architecture

chunk-based storage

and register/heartbeat mechanism

both the system scalability and manageability are improved. And decoupling the data storage and metadata management

the CorsairFS facilitates the arbitrary reorganization of the namespace

and supports multiple different data view for users. The experimental results demonstrate that the system can use the storage spaces more efficiently and achieve better transfer performance

especially for the cases with large number of small files.
