Research And Implementation Of HCOSS Object Storage System Based On Hyper Converged Infrastructure

Object storage has become an important part of modern data center infrastructure because of its comprehensive advantages in storage access performance and data sharing.The virtualization of computing,storage and network resources is the foundation of cloud data center.With the organic combination of distributed storage and computing virtualization,hyper converged infrastructure greatly promotes the development of virtual data center in operation and maintenance management,dynamic expansion,data protection and economic cost,so it becomes a hot technology of cloud data center and is widely used.Therefore,the research of object storage under hyper converged infrastructure becomes one of the key contents of building cloud data center.Based on the concept of hyper converged infrastructure,this paper integrates the cloud storage system,cloud computing resource management system and self-monitoring system independently developed by the laboratory,and studies and implements an object storage system HCOSS(Hyper-Converged Object Storage System)based on hyper converged infrastructure.First of all,the paper proposes a four-layer converged infrastructure including file gateway layer,object storage layer,resource computing layer and monitoring and scheduling layer.Based on this loose coupling layered architecture design and standard communication protocol,the three subsystems are deeply integrated and integrated,and HCOSS which integrates storage,computing and independent monitoring is developed and realized S object storage system.Then,the key technologies of object storage system,such as data distribution,load migration and dynamic expansion,are studied,and the related strategies of HCOSS are designed and implemented.In the aspect of data distribution,the problem of too many objects in a single directory is avoided through the design of directory hierarchy and capacity,and the uniformity of object distribution on a single node is improved;by customizing different distribution strategies according to the file size and combining nodes and object sets,the object distribution on the whole storage cluster is more balanced.In terms of load migration and dynamic expansion,by introducing an independent monitoring system,automatic load migration and dynamic expansion without human intervention are realized.Finally,through the construction,deployment and testing of the actual physical and virtual machine clusters,the correctness,feasibility and rationality of HCOSS functions,architecture design,data distribution,load migration and dynamic expansion strategy are verified.The results show that HCOSS can be used as an effective object storage system solution under the hyper converged infrastructure.
