Completely digital and always-on media resource. Being completely digital means that the storage media of the original media resource data is changed from tapes to disks, and from offline to online. In addition, the data reliability is improved and can be accessed anytime, eliminating the need to wait and maintain.
Reduced downtime. HCP provides extremely high system reliability. The underlying RAID data protection prevents data loss caused by disk failures, and the replication mechanism of HCP can avoid business downtime.
Data security. HCP provides a comprehensive data protection mechanism. In addition to three levels of user passwords, HCP can even lock down the data with the write once, read many (WORM) feature. Before the specified time, no one can delete or alter the file. This approach ensures file authenticity and accuracy.
Data protection. Furthermore, HCP can also provide file health check and self-healing to enhance data reliability. It creates multiple copies of the file automatically with its multicopy feature. And the system regularly performs “fingerprint” (hash value) matching for the file. If it finds out that the file doesn’t match the “fingerprint,” then the file is considered corrupted. In this case, HCP automatically replaces the corrupted one with another intact copy to ensure that the file copy is always in a good state.
Advanced metadata management. With advanced object storage technology, HCP cloud storage system provides customized metadata management. HCP can describe the content of file objects automatically, without relying on any databases or application systems. Therefore, Hitachi recommends adding an additional copy of the metadata for the file objects written to HCP through the APIs of HCP while replacing the IBM® Content Manager system. This can provide two layers of protection for the metadata.
Video files are accessible over extranet. S3 and HTTP protocols of HCP cloud storage system can support routing. As a result, HCP deployed in the headquarters can be accessed in real time by intranet and extranet users. The HTTP protocol of HCP can work within separation devices, such as firewalls and air gaps, so the video files can be accessible over extranet.
Automated collection of data from branches. Journalists in branches can upload the videos to HDI quickly via LAN, so they don’t need to wait for a long time in the offices. HDI will copy the video files to HCP cloud storage platform in the headquarters automatically. Once authorized, the HDI VM can also support file sharing between branches across regions.
Elastic scale. Automated archiving means that the HDI VM can delete local outdated data automatically according to policies. This approach can release storage space and create an unlimited storage resource pool. The deleted data will be replaced by a “stub,” which points to the data replica copied to HCP. So the user will not notice that the file has been archived.
“With the HNAS and HCP cloud storage solution, Xinhua News Agency will become the first news agency to adopt disks for streaming media asset storage in China,” explains Jiao Lu, leader of Cloud Media Asset Project Team, Audio-visual Data Division, Technology Department at Xinhua News Agency. “The object storage technology and customized metadata function of HCP provides self-description capability independent of the database and application system for streaming media files. At the same time, the standard HTTP-based access protocol offered by HCP can not only eliminate the waiting time of tape export, but also provide service for users from external networks. This can improve the read and write response speed of streaming files significantly,” he notes. “Upon the completion of the system implementation, HNAS and HCP cloud storage has become the core data platform for the TV service of Xinhua News Agency.”
