Abstract

Information is the common currency across organizations of all kinds and every day more of it is being created in the form of unstructured data or file-based data. Knowledge workers are creating increasing amounts of files such as documents, graphics, images and much more. The sheer volume of this file data or content is straining the capabilities of today’s file systems and underlying block storage to deliver the performance, scalability, reliability and integrity customers demand. A new approach to addressing this challenge is required.

The results of performance testing presented in this paper demonstrate CAStor's unique capability to provide throughput for both small and large files. It addresses small file storage and archiving to meet requirements of the most demanding environments, e.g. archiving e-mail messages on the order of hundreds of thousands a day. CAStor also provides the performance needed for large files such as health images, video and other types of content that require hundreds of megabytes per second of bandwidth.

Small file performance. CAStor performs approximately 700 writes/second in a 4-node cluster; that’s about 51 million writes/day. It goes up to 3000 writes/second in a 32-node cluster.

Large file performance. CAStor performs over 200MB/second for reads and writes in a 4-node cluster and a 32-node cluster performing at over 1GB/second on writes and approximately 900MB/second on reads.
