摘要： A method according to one embodiment includes defining a new encryption band with a length that is consistent with a redundant array of inexpensive disks (RAID) parity strip; freeing a working extent in a working stride on the RAID. In an iterative process until each stride in a source band is depleted of data: marking a source extent in a source stride from which to gather data to be re-encrypted; marking parity inconsistent in the working stride in the new encryption band; performing a second iterative process; and freeing the working extent. The second iterative process is performed until each extent in a source stride is depleted of data. Additional systems, methods and computer program products are also presented.

摘要： A RAID system is provided for detecting and correcting dropped writes in a storage system. Data and a checksum are written to a storage device, such as a RAID array. The state of the data is classified as being in a “new data, unconfirmed” state. The state of written data is periodically checked, such as with a timer. If the data is in the “new data, unconfirmed” state, it is checked for a dropped write. If a dropped write has occurred, the state of the data is changed to a “single dropped write confirmed” state and the dropped write error is preferably corrected. If no dropped write is detected, the state is changed to a “confirmed good” state. If the data was updated through a read-modified-write prior to being checked for a dropped write event, its state is changed to an “unquantifiable” state.

摘要： A Redundant Array of Independent Disks (RAID) controller receives new data that is to be written, wherein the new data is indicated in blocks of a first block size. The RAID controller reads old data, and old parity that corresponds to the old data, stored in blocks of a second block size that is larger in size than the first block size. The RAID controller computes new parity based on the new data, the old data, and the old parity. The RAID controller writes the new data and the new parity aligned to the blocks of the second block size, wherein portions of the old data that are not overwritten by the RAID controller are also written to the blocks of the second block size.
摘要翻译： 独立磁盘冗余阵列（RAID）控制器接收要写入的新数据，其中新数据以第一块大小的块表示。 RAID控制器读取旧数据和对应于旧数据的旧奇偶校验，存储在尺寸比第一块大小大的第二块大小的块中。 RAID控制器根据新数据，旧数据和旧的奇偶校验计算新的奇偶校验。 RAID控制器将新数据和新的奇偶校验与第二块大小的块对齐，其中未被RAID控制器覆盖的旧数据的部分也被写入第二块大小的块。

摘要： Method, system, and computer program product embodiments for concurrent copy of system configuration global metadata in a data storage system are provided. In one exemplary embodiment, a global data rank is quiesced, followed by an unquiesce of the global data rank except for a global metadata area. The global metadata area is updated in memory, and then unquiesced. A current range of the global metadata area to be copied is quiesced. The current range of the global metadata area is copied from a source area to a target area. The current range is unquiesced. The steps of quiescing an additional current range, copying the range from a source area to a target area, and unquiescing the current range continue until the entire global metadata area has been copied.
