摘要： A method for managing extents in a data storage system includes monitoring usage statistics for an extent residing on one or more powered-up storage devices. In the event the extent has not been accessed for specified period of time (as determined from the usage statistics), the method automatically compresses the extent and migrates the extent to an intermediate repository. Once the amount of data in the intermediate repository reaches a specified level, the method migrates the extent from the intermediate repository to one or more normally powered-down storage devices. If I/O is received for the extent while it resides in the normally powered-down storage devices or the intermediate repository, the method automatically migrates the extent from the normally powered-down storage devices or the intermediate repository to the normally powered-up storage devices. A corresponding apparatus and computer program product are also disclosed.
摘要翻译：用于管理数据存储系统中的盘区的方法包括监视驻留在一个或多个加电存储装置上的盘区的使用统计。如果在指定的时间段内（从使用统计信息确定）没有访问该范围，该方法将自动压缩该范围并将范围迁移到中间存储库。一旦中间存储库中的数据量达到指定的级别，该方法会将程序段从中间存储库迁移到一个或多个正常关闭的存储设备。如果在驻留在通常断电的存储设备或中间存储库中的范围内接收到I / O，则该方法自动将从正常关闭的存储设备或中间存储库迁移到通常供电的存储设备。还公开了相应的装置和计算机程序产品。

摘要： A method for more effectively distributing the I/O workload in a data replication system is disclosed herein. In selected embodiments, such a method may include generating an I/O request and identifying a storage resource group associated with the I/O request. In the event the I/O request is associated with a first storage resource group, the I/O request may be directed to a first storage device and a copy of the I/O request may be mirrored from the first storage device to a second storage device. Alternatively, in the event the I/O request is associated with a second storage resource group, the I/O request may be directed to a second storage device and a copy of the I/O request may be mirrored from the second storage device to the first storage device. A corresponding system, apparatus, and computer program product are also disclosed and claimed herein.

摘要： A data storage subsystem having a plurality of data compression engines configured to compress data, each having a different compression algorithm. A data handling system is configured to select at least one sample of data; operate a plurality of the data compression engines to compress the selected sample(s); determine the compression ratios of the operated data compression engines with respect to the selected sample(s); and select the data compression engine having the greatest compression ratio with respect to the selected sample(s), to compress the data. Further, the data compression engines may be in tiers from low to high in accordance with expected latency to compress data and to uncompress compressed data; and a data compression engine is selected from a tier that is inverse to the present rate of access.

摘要： A data transfer application implemented in a computational device receives a request to copy a plurality of storage volumes that form a consistency group. A determination is made that a first storage volume of the plurality of storage volumes is more likely to be written into than a second storage volume of the plurality of storage volumes, in response to receiving the request to copy the plurality of storage volumes. The first storage volume is copied before copying the second storage volume, in response to determining that the first storage volume is more likely to be written into than the second storage volume.

摘要： In one aspect of the present description, a data preservation function is provided for preserving a set of data on a source storage device at a point in time, and includes identifying as a function of prior update usage, such as input/output usage, of the data to be preserved, a portion of the data which is more likely to be the subject of updates during at least a portion of the data preservation operation as compared to the remaining portion of the data to be preserved, and copies the identified portion of the data to be preserved to a target storage device. In another aspect, the size of the portion of data to be identified is variable. Other features and aspects may be realized, depending upon the particular application.

摘要： In a shell utility computer program code configured to cause at least one computer processor comprising one host computer system to connect to a second host computer system, and to cause the second host computer system to execute at least one command provided to one host computer system, the computer program code is configured to cause the one host computer system to selectively alter a pre-existing return code for use on shell utility error; and to cause the one host computer system to, in the absence of an alteration to the pre-existing return code, select a pre-existing return code of the shell utility as a default.
