Abstract: Traditional cloud disks based on NAS storage have the disadvantages of poor scalability,low response performance,unreliable data and low security.This paper presents a design and implementation scheme based on the distributed object storage system of Ceph.The scheme can build high performance,high reliability and scalable cloud disks.The pools of Ceph storage clusters are based on the X86 server,in order to the service of object storage is published through multi-object gateway with soft load balancing to enhance the capacity of request and response in cloud disk and achieve the functions of isolation and security in object data by integrating with token-based authentication systems.Experiments show that the design and implementation scheme meets the requirements of practical application.
