论文摘要
内容丰富的网站通常将其图像作为单个文件或更昂贵的二进制数据库对象容纳。两种方法都对高额货币成本的存储资源提出了很高的需求。廉价的共享服务帐户对磁盘和计算资源有严格的限制，这些磁盘可阻止其用于托管内容丰富的网站。为了最大程度地减少这些有限资源的负载，可以将大量图像或其他记录连接到一个文件中，并使用Linux Utility DD在文件中独立于文件的延迟延迟。该解决方案及其性能是针对（a）一个网站提供的，该网站包含8000多本拥有超过350万个250 kbyte页面图像，（b）基于网站的8600万个死亡记录的数据库，以及（c）使用800个神经图像数据库，每个数据库都有150万张记录。这些不同的应用证明了解决方案的功效，可伸缩性和一般效用。
Content-rich websites typically house their images as individual files or as more costly binary database objects. Both methods place high demands on storage resources with commensurate high monetary cost. Inexpensive shared service accounts come with strict limits on disk and computing resources which prevent their use for hosting content-rich websites. To minimize the load on these limited resources, large numbers of images or other records may be concatenated into a single file and delivered with short latency independent of location within the file using Linux utility dd. This solution and its performance are presented for (a) a website which houses 8000+ genealogical reference books with more than 3.5 million 250-Kbyte page images, (b) a website-based database of 86 million death records, and (c) a cluster computing application which utilizes 800 neuroimaging databases, each with 1.5 million records. These disparate applications demonstrate the efficacy, scalability, and general utility of the solution.
