| 摘 要： | 基于廉价磁盘冗余阵列（RAID）方法和逻辑卷管理（LVM）工具，将一台机架式服务器和五台磁盘阵列进行连接管理，实现了一种单一逻辑磁盘容量达90 TB的大规模存储空间。该方案注重了系统的稳定性和数据的安全性。磁盘阵列采用串联方式，增强了可扩展性，理论上可以无限扩展。实际应用表明，该方案方便了数值预报业务数据的安全、快速存取，并具有容量的可扩展性。满足了省级气象部门对科研数据存储的需求，尤其是数值预报结果检验工作对大规模存储的需求。

| Abstract: | Based on the Redundant Array of Inexpensive Disks (RAID), and Logical Volume Management (LVM) tools, a rack mount server and five connected disk arrays are combined into a single logical disk with massive storage space of up to 90 TB. This program focuses on the stability of the system and the data security on the disk array series, increases the scalability, and theoretically can expand indefinitely. Practical application shows that this program facilitates the security and fast access of the data used operationally in numerical weather prediction, and has a capacity of scalability, so to meet the scientific data storage requirements of meteorological departments at the provincial level, especially the needs of numerical prediction verification for mass storage. |
