Contents I. Introduction
The development of information technology makes the information data show the growth of geometric progression, the data storage has become the major enterprises and units of an important issue. And the speed cycle of storing data doubles is getting shorter and shorter, which makes it impossible to meet the need for data growth by relying solely on the increase in hardware storage devices. In meteorological data, meteorological satellite data is intensive data, large data volume and requires long-term stable storage, and can be based on the needs of meteorological applications for these data to read quickly, these applications on the storage system I / O performance a higher demand. So how to build a high-performance, highly scalable, highly available and manageable and secure storage system is becoming increasingly imminent.
