A Case for CAS: Reshaping Conventional Thinking About Storage

摘要

Until now, the industrywide embrace of storage networking and the rapid coupling of countless petabytes of data have shaped conventional storage thinking in two fundamental ways: Storage improvements must always be faster and cheaper, and complexity must be tolerated to achieve efficiency. Such thinking is rooted in the build-out process that evolved storage networks to where they are today-at the epicenter of a company's business. But new challenges posed by Web-based service models, increasing regulatory requirements, heightened security, data preservation, and storage optimization are ushering out the old thinking and bringing to light the value of an architecture called content addressed storage, or CAS. CAS is key to business because it overcomes the threats posed by these new storage challenges-the unmanaged, exponential growth in capacity and number of fixed-content objects.
