Application of High Performance Meteorological Data Storage Cluster and Online Extension
Abstract:In order to meet the rapid growth and efficient application of meteorological data, it is based on SAN and GPFS to design a high-performance storage cluster for data storage, and with the rapid growth of the amount of data, to achieve flexible online extension is very important. With the storage design of National meteorological data storage and retrieval system, wind energy resource data shared system and wind energy resources numerical simulation system,to explain the SAN and GPFS based storage cluster architecture, and highlights it’s flexible online extension technology. Online extension technology based on SAN and GPFS storage cluster include server node, storage capacity and file system capacity extension, and makes the meteorological data storage system flexible to the business data changes, the system has excellent scalability and adaptability.
