Abstract: A method and a controller for managing a storage array is presented. The storage array is divided into a first subset of storage devices and a second subset of storage devices according to degrees of wear of storage devices, such that a degree of wear of each of storage device in the first subset is greater than or equal to a degree of wear of any storage device in the second subset, and then, to-be-written data are written into the physical storage devices in the first subset. Therefore, service lives of storage devices in the second subset may be extended relatively by shortening service lives of storage devices in the first subset.

Abstract: A electronic device includes a plurality of first photosensitive chips, one first fusion chip, and one processing chip. Each first photosensitive chip is connected to the first fusion chip by a respective data transmission channel and is configured both to generate a MIPI protocol-based data stream and to transmit said data stream to the first fusion chip by the respective data transmission channel. The first fusion chip is connected to the processing chip by a data transmission channel and is configured to converge data streams received via a plurality of data transmission channels connected to the plurality of first photosensitive chips, to obtain a first high-speed convergent data, and to send the first high-speed convergent data to the processing chip. The processing chip is configured to receive the high-speed convergent data stream and obtain an image by using the received data stream.

Abstract: A method for extending life of a storage system, wherein a storage controller determines a source solid-state disk (SSD) in a disk group with a capacity usage ratio greater than an average capacity usage ratio of the disk group. The capacity usage ratio of the source SSD is a ratio of a used capacity of the source SSD to an available capacity of the source SSD. The storage controller selects at least one destination SSD in the disk group with a capacity usage ratio less than the average capacity usage ratio of the disk group. And then the storage controller calculates an amount of data to be migrated from the source SSD, based on the capacity usage ratio of the source SSD and the average capacity usage ratio. At last, the storage controller migrates the data to be migrated from the source SSD to the one or more destination SSDs.
Abstract translation: 一种用于延长存储系统寿命的方法，其中存储控制器确定磁盘组中的源固态磁盘（SSD），其具有大于所述磁盘组的平均容量使用率的容量使用率。 源SSD的容量使用率是源SSD的使用容量与源SSD的可用容量的比率。 存储控制器选择磁盘组中的至少一个目标SSD，其容量使用率小于磁盘组的平均容量使用率。 然后存储控制器基于源SSD的容量利用率和平均容量使用率来计算要从源SSD迁移的数据量。 最后，存储控制器将要迁移的数据从源SSD迁移到一个或多个目标SSD。
