Redes san (Storage Área Network)

Abstract

Computing is based on information. Information is the underlying resource on which all computing processes are based; it is a company asset. Information is stored on storage media, and is accessed by applications executing on a server. Often the information is a unique company asset. Information is created and acquired every second of every day. To ensure that any business delivers the expected results, they must have access to accurate information, and without delay. The management and protection of business information is vital for the availability of business processes. The advent of client/server computing created a new set of problems, such as escalating management costs, as well as new storage management problems such as those introduced by government and legal requirements to safely maintain and guard information. Information that once was centralized in a mainframe environment is now dispersed across the network, geographically or locally, and it is this that introduces the potential for mismanagement to occur. With geographically dispersed data, coupled with the need for instant access to information, an infrastructure model that supported the needs of its users was a necessity.
