分布式存储在媒资系统的应用设计与实现

Application Design and Implementation of Distributed Storage in Media Resource System

广电、媒体行业在节目网络制播领域不断增长的业务对IT部门的要求越来越高,尤其媒体网业务对大规模的媒体数据处理提出了更高的要求。电视台等大型媒体机构的节目制作部门需要不断地提升服务器、存储、工作站、交换设备的数量和性能,造成需要不断追加采购和运作成本的局面,海量存储在广电、媒资的应用也愈发广泛。分布式存储充分利用软件定义存储的思想,是集文件、块和对象存储在内的统一存储,同时也可作为互联网应用的云端存储和OpenStack等云平台的后端存储,实现与云的无缝对接。

The growing business of broadcasting,television and media in the field of program network production and broadcasting has become more and more demanding for IT department,especially the media network services have placed higher demands on large-scale media data processing.The program production departments of large media organizations such as TV stations need to constantly improve the numberand performance of servers,storage,workstations and switching equipment,resulting in the need for additional procurement and operating costs,and mass storage is increasingly widely used in radio,television and media resources.Distributed storage takes full advantage of the idea of software-defined storage,which is a unified storage of files,blocks and objects.Meanwhile,it can also be used as the cloud storage of Internet applications and the back-end storage of OpenStack and other cloud platforms to achieve seamless connection with the cloud.
