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： Provided are a method, system, and article of manufacture for iterative data secret-sharing transformation and reconversion. In one aspect, data secret-sharing transformation and reconversion is provided in which each bit of an input stream of bits of data is split, on a bit by bit basis, into a pair of secret-sharing bits, and the secret-sharing bits of each pair of secret-sharing bits are separated into separate streams of secret-sharing bits. In this manner, one secret-sharing bit of each pair of secret-sharing bits may be placed in one stream of secret-sharing bits and the other secret-sharing bit of each pair may be placed in another stream of secret-sharing bits different from the one stream of secret-sharing bits. Confidentiality of the original input stream may be protected in the event one but not both streams of secret-sharing bits is obtained by unauthorized personnel. In another aspect, for an input stream of N bits, each received bit of the N bits of the input stream of data, may be interatively split, on a bit by bit basis, into a pair of secret-sharing bits, to generate as few as N+1 secret-sharing bits from the input stream of bits N bits. Other features and aspects may be realized, depending upon the particular application.
摘要翻译：提供了一种用于迭代数据秘密共享转换和重新转换的方法，系统和制造。在一个方面，提供了数据秘密共享转换和重新转换，其中将数据位的输入流的每个位逐位分割成一对秘密共享位，并且秘密共享位每对秘密共享比特被分成独立的秘密共享比特流。以这种方式，每对秘密共享比特的一个秘密共享比特可以被放置在一个秘密共享比特流中，并且每对的另一个秘密共享比特可以被放置在另一个不同的秘密共享比特流中从一个秘密共享位流。在未经授权的人员获得秘密共享位的情况下，原始输入流的保密性可能受到保护。在另一方面，对于N位的输入流，输入数据流的N位的每个接收位可以逐位地分开成一对秘密共享位，以生成为很少作为N位1个秘密共享位从输入流的位N位。可以根据具体应用实现其它特征和方面。

In another aspect, the size of the portion of data to be identified is variable. In one embodiment, the size of the portion of data to be identified is a function of a parameter of the command, such that a user can specify the command parameter which affects the size of the portion of data which is prewritten to the target storage device. The parameter may be, for example, a percentage of the data to be preserved, such that a user can specify the percentage of the point-in-time data which is prewritten to the target storage device. Alternatively, the parameter may be, for example, a probability of a collision occurring, such that a user can specify a probability of a collision occurring. Other features and aspects may be realized, depending upon the particular application.

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： 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.
