Enterprises and service providers are facing tremendous storage growth, driven by the explosion of large digital files such as video, audio, images, reference, and nearline archive. Scalable, low cost, easy-to-manage bulk storage is a top priority for customers looking to manage growth and control costs.
Traditional SAN and NAS solutions, designed for transactional data processing such as databases and e-mails, bear high prices and limit scalability. Attempting to provide more scalable file storage, many storage vendors have relied on cluster file system technology (also known as shared file system) to aggregate multiple SAN storage arrays. Today, this legacy technology has become a significant barrier for customers seeking to reduce complexity and cost while increasing reliability.
