摘要： Package controller of a flash package, upon receiving an update data write request with respect to a first logical storage area corresponding to a first LU that is treated as a backup target, manages a first physical storage area as a backup storage area in a state where pre-update data is maintained, allocates a second physical storage area to the first logical storage area, and writes the update data to the second physical storage area. The package controller, upon receiving an update data write request with respect to a second logical storage area corresponding to a second LU that is treated as a non-backup target, manages a third physical storage area allocated to the second logical storage area as an invalid storage area, and writes the update data to a fourth physical storage area newly allocated to the second logical storage area.

摘要： A storage system comprises a first controller and a plurality of storage devices. The plurality of storage devices configure RAID, each of which includes one or more non-volatile memory chips providing storage space where data from a host computer is stored, and a second controller coupled to the non-volatile memory chips. In case where the first controller receives an update request to update first data to second data from the host computer, the second controller in a first storage device of the storage devices is configured to store the second data in an area different from an area where the first data has been stored, in the storage space of the first storage device; generate information that relates the first data and the second data; and generate an intermediate parity based on the first and the second data.
摘要翻译：存储系统包括第一控制器和多个存储设备。多个存储设备配置RAID，每个RAID包括提供存储来自主计算机的数据的存储空间的一个或多个非易失性存储器芯片，以及耦合到非易失性存储器芯片的第二控制器。在第一控制器接收到从主计算机将第一数据更新为第二数据的更新请求的情况下，存储设备的第一存储设备中的第二控制器被配置为将第二数据存储在不同于第一数据已被存储在第一存储设备的存储空间中; 生成与第一数据和第二数据相关的信息; 并且基于第一和第二数据生成中间奇偶校验。
