Abstract: A method for reading data stored in a redundant array of independent disks (RAID). The RAID includes a RAID controller, a first cache, and a hard disk including a hard disk controller and a second cache. The method includes: receiving a read request, wherein the read request comprises an identifier of a to-be-read logical block; sending a first command to a hard disk controller of the hard disk when the first cache does not comprise data stored in the to-be-read logical block, wherein the first command is used to instruct the hard disk controller of the hard disk to return the data of the to-be-read logical block from the second cache of the hard disk; outputting the returned data, and caching the returned data in the first cache; and controlling the hard disk controller of the first hard disk to delete the returned data stored in the second cache.

Abstract: This application provides an optical chip. The optical chip includes an optical substrate, and a first functional layer, a first space layer, and a second functional layer that are sequentially disposed on the optical substrate. A second optical structure is formed at the second functional layer. The second optical structure includes a second inter-layer coupling structure and a second intra-layer transmission structure, and the second intra-layer transmission structure is located in a first area of the second functional layer. A first optical structure located in a second area is formed at the first functional layer. The first optical structure includes a first inter-layer coupling structure and a first intra-layer transmission structure, and a projection of the second area in a normal direction of a plane of the optical substrate does not overlap with a projection of the first area in the normal direction of the plane of the optical substrate.
