The development of high performance computing has posed a tremendous demand on storage capacity and I/O performance, storage system has entered the Petabyte era. Application demands drive the change of storage architecture. Object-based storage is becoming the new direction of massive network storage systems. Object-based storage combines the advantages of SAN and NAS, adopts an object-based interface, and offloads some work of traditional file system to intelligent object-based storage devices, so greatly enhance the performance, reliability, and scalability of storage system. On the other hand, because the storage system scale of high performance computing is very large, the amount of storage nodes is very huge, so features such as power, size and weight have been the factors that cannot be neglected. This paper aims at the key component of object-based storage system - object storage controller, and proposes a novel design of object storage controller based on SOC. Measurement results show that the object storage controller designed by us not only optimize the performance of object-based storage system, but also has advantage in the respects of power, size and weight, so it's very suit for building the object-based storage system for high performance computing.
