  • Publication number: 20240323555
    Abstract: An image sensor device may include a pixel sensor array and a black level correction (BLC) region. The BLC region may include a sensing region in a substrate and a light-blocking layer above the sensing region. An anti-reflection array may be formed in the light-blocking layer. The anti-reflection array includes holes, trenches, and/or other structural features such that the light-blocking layer includes two or more areas in which the top surface of the light-blocking layer is at different heights in the image sensor device. The different heights of the top surface of the light-blocking layer reduce the likelihood of light being reflected off of the light-blocking layer and toward the pixel sensor array. The anti-reflection array may reduce the likelihood of occurrence of flares or hot spots in images generated by the image sensor device, which may increase the image quality of the images generated by the image sensor device.

  • Patent number: 11941265
    Abstract: Techniques for managing metadata storage units involve: in response to receiving, from a client, a request for allocating a target number of metadata storage units, determining a first number of available metadata storage units remaining in a metadata storage space of a storage system after the allocation is performed; and if the first number is not less than a reserved number, allocating the target number of metadata storage units from the metadata storage space for the client to use, wherein the reserved number is associated with a usage condition of the metadata storage units in the storage system. Accordingly, such techniques can effectively manage metadata and improve the performance of a system.

  • Patent number: 11747990
    Abstract: Techniques for managing a redundant array of independent disks (RAID) involve detecting an abnormality of a storage device in a RAID. The techniques further involve resetting the storage device in response to detecting the abnormality. The techniques further involve storing an address of a write operation for the RAID within a preset time period, so as to rebuild the RAID in the case that the storage device is recovered within the preset time period. Accordingly, temporary errors of the RAID can be efficiently handled, the number of downtime of the RAID caused by the storage device or the back end can be reduced, and computing resources and time required to rebuild the RAID can be significantly reduced.

  • Patent number: 11507482
    Abstract: Technology is disclosed for recovering the consistency of a RAID (Redundant Array of Independent Disks) metadata database when data corruption is detected in the RAID metadata database. The RAID metadata database includes super sectors, stage sectors, and a data region. Valid data within the data region is a contiguous set of sectors extending from a head sector to a tail sector. In response to data corruption in one of the two super sectors, a set of pointers contained in the other super sector is used to identify the head sector and tail sector. In response to data corruption in both super sectors, the head sector and tail sector are located based on the contents of the sectors in the data region. Techniques are also disclosed for recovering consistency when the data corruption occurs in the stage sectors and/or data region.

  • Publication number: 20220129437
    Abstract: Technology for configuration metadata recovery that detects a reliability failure regarding configuration metadata stored in non-volatile data storage of a data storage system. The configuration metadata indicates how a metadata database is stored in the non-volatile data storage of the data storage system. In response to detection of the reliability failure regarding the configuration metadata, the technology identifies valid generations of the configuration metadata that are currently stored in the non-volatile data storage of the data storage system, and determines a user-selected one of the valid generations of the configuration metadata. The metadata database is accessed based on the user-selected one of the valid generations of the configuration metadata.
