Abstract: Embodiments of the application provide a file access method. A computing node receives a file open request that carries a file identifier. The computing node obtains an index node of a file that is identified by the file identifier. The computing node further obtains, based on the index node, a physical address space of a memory area in a file storage area, in which the file is stored. The computing node allocates a virtual address space to the file, and recodes a virtual-physical address mapping relationship by using a memory page table. The virtual-physical address mapping relationship includes a mapping relationship between the virtual address space and the physical address space.

Abstract translation: 应用的实施例提供文件访问方法。 计算节点接收携带文件标识符的文件打开请求。 计算节点获取由文件标识符标识的文件的索引节点。 计算节点还基于索引节点获得文件存储区域中的存储区域的物理地址空间。 计算节点为文件分配虚拟地址空间，并通过使用内存页表重新生成虚拟 - 物理地址映射关系。 虚拟物理地址映射关系包括虚拟地址空间和物理地址空间之间的映射关系。
