在当今瞬息万变的信息社会中，信息的可靠性和及时性成了企业竞争的关键。因特网的高速发展，使当今社会成为网络联通的社会。许多大企业的通信平台传输数据爆炸性地增长，使得其存储能力要求以每年平均５０％～１００％的增长。传统的网络架构面对源源不断数据流显得力不从心。这就要法语把服务器与存储设备集中起来，以便统一地管理数据。数据管理的实质是存储管理，完善的存储策略既要全面支持现有企业环境中开放式多平台存储环境，又要应付当今业务应用中数据的飞速增长。当今的存储管理要求创建一种独立于ＬＡＮ，统一的、扩展性很好的存储架构，因此，存储域网络（ＳＡＮ）就应运而生。
In today’s rapidly changing information society, the reliability and timeliness of information has become the key to business competition. The rapid development of the Internet has made today’s society a networked network. Many big business communication platform transmission data explosive growth, making its storage capacity requirements at an annual average of 50% to 100% growth. The traditional network architecture in the face of a steady flow of data incapacity. This requires French to centralize server and storage devices for unified management of data. The essence of data management is storage management. A sound storage strategy not only fully supports the open multi-platform storage environment in existing enterprise environments, but also meets the rapid growth of data in business applications today. Today’s storage management requires the creation of a unified, scalable storage architecture that is independent of the LAN, so a storage area network (SAN) emerges.
