Implementation of a Software-Defined Storage Service with Heterogeneous Storage Technologies

SDS becomes more and more popular, and several companies have announced their product. But the generic standard still has not appeared, most products are only appropriate for their devices and SDS just can integrate a few storages. In this thesis, we will use the Open Stack to build and manage the cloud service, and use software to integrate storage resources include Hadoop HDFS, Ceph and Swift on Open Stack to achieve the concept of SDS. The software used can integrate different storage devices to provide an integrated storage array and build a virtual storage pool, so that users do not feel restrained by the storage devices. Our software platform also provides a web interface for managers to arrange the storage space, administrate users and security settings. For allocation of the storage resources, we make a policy and assign the specific storage array to the machine that acquires the resource according to the policy.
