Isilon delivers increased performance for file-based data applications and workflows, from the highest performance, I/O-intensive applications, to primary and secondary storage, to nearline archives, all from a single file system architecture. Powered by the OneFS® Operating System, all components in an Isilon cluster create a unified pool of highly efficient storage-with a proven 80 percent storage utilization rate. Isilon’s high efficiency means less physical storage is required to house the same amount of data, reducing capital and operating costs.
