安防行业随着监控点的不断增加、应用需求的不断增多,开始正式迈入大数据时代。以一个中等城市的视频监控系统为例,600个卡口点位和10000路的视频监控,一年的过车记录就有20亿条左右,而一年的录像数据则达到1万3千个TB,即13个PB,面对这样的海量数据,以IPSAN为代表的传统存储已经很难适应应用,云存储正是在这样的形势下应运而生,它通过存储虚拟化、分布式系统、集群化应用等一系列技术,满足大数据时代下的海量视频存储需求。 Security industry with the growing number of monitoring points, application requirements continue to increase, began to formally enter the era of big data. Taking a video surveillance system in a medium-sized city as an example, 600 card points and 10,000 video surveillance systems have a record of about 2 billion car trips a year and a record of 13,000 videos a year TB, that is, 13 PB, in the face of such huge amounts of data, traditional storage represented by IPSAN has been difficult to adapt to the application. Cloud storage is emerging under such circumstances. Through storage virtualization and distributed systems, Clustering applications and a series of technologies to meet the massive data storage needs of the era of big data.
