There is no doubt that the demand for storage has been increasing exponentially. Business communications have evolved from simple text to elaborate graphics-heavy documents and fancy graphics-based presentations. iCommerce, eCommerce, and other ever-increasing eBusiness solutions that require corporate data centers to provide information in various formats have all contributed to the explosion in demand for storage capacity. Enterprise class businesses are deploying huge RAID devices that are Terabytes (TB) in size. 1.2 Requirements for Nonstop Data Availability Even though cost-per-megabyte for storage is declining at the rate of 35% to 40% per year, business requirements for fault-tolerance, high availability, disaster recovery and online backup have significantly increased the costs of managing all the storage. As the stored data has become more critical and irreplaceable, the need for uninterrupted availability of data and for fast and complete recovery is now absolutely required. Leading industry analysts have estimated that the ratio of management cost versus acquisition cost for storage has increased over time to 8:1. This means that unless an alternative to the traditional directattached storage (DAS) model is implemented, an additional eight dollars will be spent to perform on-going maintenance and management for every dollar spent on purchasing storage systems. Such quickly mounting costs make it impractical for a business to grow |
