Industry Background

Demand For New Approaches to Storing and Managing Fixed Content

Traditionally, high-cost disk drives that are highly-available and optimized for performance, such as Fibre Channel and SCSI, have been used to store dynamic, transaction-oriented database information, while fixed content has been moved onto less expensive, low-availability storage systems such as tape and optical disk for long-term storage. Historically, most research and development in the storage industry has focused on improving the speed and performance characteristics for managing dynamic information. However, as retention periods lengthen and demands placed on long-term storage become more complex, organizations are increasingly looking for cost-effective, intelligent storage solutions with high-availability that can scale to tackle the exponential growth of fixed content.

In light of these factors, organizations are changing the way they approach the storage and management of fixed content in a number of ways.

· Adoption of low-cost, capacity optimized disk storage — The introduction of low-cost, capacity-optimized ATA, and later Serial ATA, or SATA, disk drives is changing the way organizations store fixed content. More organizations are creating disk-based tiered storage environments, in which data that is highly transactional or mission critical is stored on traditional performance optimized disk drives, such as Fibre Channel or SCSI, while fixed content data is moved to lower cost tiers that are optimized for capacity. These lower cost tiers generally utilize SATA disk drives. As fixed content continues to grow faster than other data types, the result has been a shift from the need for performance-optimized storage to capacity-optimized storage. In addition, the need for ready access to information has led to the replacement of some tape and optical disk solutions with SATA disk drives. IDC estimates that the market for capacity-optimized storage disk systems will grow from $6.4 billion in end-user spending in 2007 to $18.4 billion in 2012, at a five-year compound annual growth rate (CAGR) of 23.6%.
