摘要： Provided are a method, system, and program for an adaptor to read and write to system memory. A plurality of blocks of data to write to storage are received at an adaptor. The blocks of data are added to a buffer in the adaptor. A determination is made of pages in a memory device and I/O requests are generated to write the blocks in the buffer to the determined pages, wherein two I/O requests are generated to write to one block split between two pages in the memory device. The adaptor executes the generated I/O requests to write the blocks in the buffer to the determined pages in the memory device.

摘要： Provided are a method, system, and article of manufacture for determining whether to use a full volume or repository for a logical copy backup space. A determination is made of a source volume to backup using a logical copy operation. The logical copy operation is completed upon indicating the source volume data to backup. During a logical copy duration, point-in-time data in the source volume as of a point-in-time when the logical copy was established is copied to a backup space in response to receiving an update to the point-in-time data. A history of writes to the source volume is processed to determine whether to allocate a full target volume as the backup space providing a corresponding data unit for each data unit in the source volume or allocate a repository as the backup space, wherein the repository uses less storage space than the full target volume. The logical copy operation using the determined full target volume or repository as the backup space is initiated.

摘要： An apparatus, system, and method are disclosed for selecting a space efficient repository. A cache receives write data. A destage module destages the data sequentially to a coarse grained repository such as a stride level repository and destages a directory entry for the data to a coarse grained directory such as a stride level directory if the data satisfies a repository policy. In addition, the destage module destages the data to a fine grained repository such as a track level repository overwriting an existing data instance and destages the directory entry to a fine grained directory such as a track level directory if the data does not satisfy the repository policy.

摘要： A method for allocating space in a cache based on media I/O speed is disclosed herein. In certain embodiments, such a method may include storing, in a read cache, cache entries associated with faster-responding storage devices and cache entries associated with slower-responding storage devices. The method may further include implementing an eviction policy in the read cache. This eviction policy may include demoting, from the read cache, the cache entries of faster-responding storage devices faster than the cache entries of slower-responding storage devices, all other variables being equal. In certain embodiments, the eviction policy may further include demoting, from the read cache, cache entries having a lower read-hit ratio faster than cache entries having a higher read-hit ratio, all other variables being equal. A corresponding computer program product and apparatus are also disclosed and claimed herein.
摘要翻译：本文公开了一种基于媒体I / O速度在高速缓存中分配空间的方法。在某些实施例中，这种方法可以包括在读取缓存中存储与更快响应的存储设备相关联的高速缓存条目以及与较慢响应的存储设备相关联的高速缓存条目。该方法还可以包括在读取高速缓存中实现逐出策略。这种驱逐策略可以包括从读取的缓存降低响应较快的存储设备的高速缓存条目比缓慢响应的存储设备的缓存条目更快，所有其他变量相等。在某些实施例中，驱逐策略还可以包括从读取的缓存降级具有比具有较高读取命中率的高速缓存条目更低的读命中率的高速缓存条目，所有其他变量相等。本文还公开并要求相应的计算机程序产品和装置。

摘要： Embodiments of the disclosure relate to archiving data in a storage system. An exemplary embodiment comprises making a flash copy of data in a source volume, compressing data in the flash copy wherein each track of data is compressed into a set of data pages, and storing the compressed data pages in a target volume. Data extents for the target volume may be allocated from a pool of compressed data extents. After each stride worth of data is compressed and stored in the target volume, data may be destaged to avoid destage penalties. Data from the target volume may be decompressed from a flash copy of the target volume in a reverse process to restore each data track, when the archived data is needed. Data may be compressed and uncompressed using a Lempel-Ziv-Welch process.
摘要翻译：本公开的实施例涉及在存储系统中归档数据。示例性实施例包括在源卷中进行数据的闪速复制，压缩闪存中的数据，其中数据的每个轨道被压缩成一组数据页，并将压缩的数据页存储在目标卷中。可以从压缩数据盘区池中分配目标卷的数据盘区。在每一步数据的数据被压缩并存储在目标卷中之后，数据可能会被排除以避免流失的惩罚。当需要归档数据时，目标卷的数据可以以相反的过程从目标卷的闪存副本中解压缩，以恢复每个数据轨道。数据可以使用Lempel-Ziv-Welch进程进行压缩和解压缩。
