ABSTRACT
In 2000, seeing the challenges with traditional storage architectures, and the pace at which file-based data was increasing, the founders of Isilon began work on a revolutionary new storage architecture-the OneFS Operating System. The fundamental difference of EMC Isilon storage is that it uses intelligent software to scale data across vast quantities of commodity hardware, enabling explosive growth in performance and capacity. The three layers of the traditional storage model-file system, volume manager, and RAID-have evolved over time to suit the needs of small-scale storage architectures, but introduce significant complexity and are not well adapted to petabyte-scale
providing a unifying clustered file system with built-in scalable data protection, and obviating the need for volume management. OneFS is a fundamental building block for scale-out infrastructures, allowing for massive scale and tremendous efficiency.
