完全数字捕获系统强调存储和网络

“When we converted to an all-digital, file-based capture system,” explains Roland Rodgers, BBC NI’s technology development and infrastructure specialist, “the production team was immediately able to take advantage of the file-based workflow—but we did not anticipate the impact it created on the storage systems and networks.”Dramatically increasing data volumes and more formats needing transcodingthreatened to create bottlenecks. “Frankly, the IT team was surprised at the impact of the change,” Rodgers recalls. “It became obvious that we had to plan carefully and upgrade our systems in a smart way to avoid creating delays for the editors.”

升级提供灵活性和避免Bottlenecks

该解决方案是为了大修工作流系统，升级应用程序和网络以及存储系统，并展开现有的StorNext环境以包括两个光纤通道连接的位置。随着累积的材料，添加了oneTape归档，以便高性能磁盘仅用于当前的产品。稍后，增加了第二个存档来支持长期的当前事务特征。时间，团队增加了数百个数字的新磁盘存储，扩展了SAN，用更高的性能模型替换了Stornext控制器，并升级了驱动器和媒体档案。“除了改变控制器外，几乎所有升级都是无颠扰的，”Rodgers笔记。

Meeting Needs For Performance, Redundancy, and DR Protection

“The new system has much faster performance overall,” says Rodgers, “and it provides much more flexibility. Now, we have 200 seats with high-performance access to all the shared content through the StorNext File System—so that more editors can work faster and more collaboratively, and spend less time moving themselves or the content around.” Each of the two Belfast locations has performance disk resources and a StorNext AEL6000 tape library. Rodgers says, “One holds the news proxy files on disk and nearly a petabyte of the Rewind archive while the other one holds all the full-quality content for the news. Dividing the work gives us maximum performance, but the two sites are linked via Fibre Channel. So, in a pinch either one can act as a backup for the other. We have one StorNext File System spanning the entire system, making it easy to share files.”

Mirrored Libraries Provide Protection And A Low-cost Archive

“一旦数据击中工作磁盘，Stornext会自动为LTO库中的每一个副本写入两个副本，”Rodgers说。“那样，我们有一份存储在备份和DR保护的两个地方的一切副本。当文件不再积极工作时，我们删除磁盘副本以释放新内容的空间 - 这有助于我们在磁盘容量上节省金额。然而，StorDext和Cinegy查看磁盘和磁带上的所有内容，使编辑器可以访问所有内容。“编辑通常从磁盘上的代理工作，并且CineGyOMACLY从磁盘或磁带中提取全质量版本。

Maximum Performance And Non-disruptive Upgrades

“新闻镜头以高速摄取到磁盘环境 - 斯特兰文本支持多个并行转码操作 - 因此数据可用于内容生产团队的最小延迟，”Rodgers解释说。“StorNext让我们在所有磁盘资源中获得最大的性能。“多年来，我们从一个最小大小的实现 - 一个存储节点和一个库移动到一个位置 - 到完全冗余，高度弹性的双站点的实现，而无需对我们的用户进行重大停机或中断。这种能力是Stornext的力量，以及它和肺一起工作的方式。“
