摘要： In one embodiment, pursuant to migrating the data from the first to the second storage medium, the data is allocated to the second storage medium while retaining an allocation of the data in the first storage medium. If the data is migrated from the second storage medium back to the first storage medium, the data is pointed to the allocation of the data in the first storage medium to alleviate data movement from the second storage medium to the first storage medium. If the allocation of the data in the first storage medium is determined to be needed for other data, the allocation of the data in the first storage medium is freed.

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.
摘要翻译：本文公开了一种在数据复制系统中更有效地分布I / O工作负载的方法。在所选择的实施例中，这种方法可以包括生成I / O请求并且识别与I / O请求相关联的存储资源组。在I / O请求与第一存储资源组相关联的情况下，I / O请求可以被定向到第一存储设备，并且I / O请求的副本可以从第一存储设备镜像到第二存储设备储存设备。或者，在I / O请求与第二存储资源组相关联的情况下，I / O请求可以被定向到第二存储设备，并且I / O请求的副本可以从第二存储设备镜像到第一存储设备。

摘要： Exemplary method, system, and computer program embodiments for data migration between first and second storage mediums of an available plurality of storage mediums in a computing storage environment are provided. In one embodiment, pursuant to migrating the data from the first to the second storage medium, the data is allocated to the second storage medium while retaining an allocation of the data in the first storage medium. If the data is migrated from the second storage medium back to the first storage medium, the data is pointed to the allocation of the data in the first storage medium to alleviate data movement from the second storage medium to the first storage medium. If the allocation of the data in the first storage medium is determined to be needed for other data, the allocation of the data in the first storage medium is freed.

摘要： A system for analyzing mutually exclusive conflicts among a plurality of redundant devices in a computer system includes a data management module operable on the computer system. The data management module parses through status data generated by the plurality of redundant devices to identify an error condition in one of the plurality of redundant devices, generate metadata describing the error condition, and take action to resolve the error condition. A method of analyzing mutually exclusive conflicts among redundant devices in a computer system includes collecting status data from the redundant devices, identifying an error condition, generating metadata describing the condition, analyzing the metadata to determine a lowest-level or least impacting redundant device that is the root cause of the condition, and taking an action to resolve the condition.

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 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.
