Abstract: A method for processing a non-cache data write request, a cache, and a node are provided. The method includes: A cache receives a first non-cache data write request from a first processor, and sends the first non-cache data write request to a node, where the first non-cache data write request includes a first address. If the cache determines that the first address is stored in the cache, the cache obtains first data corresponding to the first non-cache data write request from the first processor. When receiving a first data buffer identifier from the node, the cache sends the first data to the node. After receiving the first non-cache data write request, if the cache determines that the first address is locally stored, the cache may obtain the first data from the processor. After receiving the first data buffer identifier, the cache may send the first data to the node.
