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. 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 dynamic consistency group formation, in one embodiment, includes creating a snapshot of first data stored on a source storage system with respect to data content and data structure, copying the snapshot to a target storage system, detecting one or more write operations affecting data on the source storage system while copying the first data, detecting one or more collisions affecting the first data on the source storage system, wherein a collision occurs whenever the write operations affect the first data prior to the first data being written, setting a consistency group interval which represents an interval duration between successive snapshot create-and-copy events, and altering the consistency group interval to minimize collisions affecting data on at least one of the storage systems. Other methods for dynamic consistency group formation are also described.

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： 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 read/write ratio for each of a plurality of data segments classified in a hot category as hot data segments is determined. Each of the plurality of hot data segments is ordered by the read/write ratio in a descending order. Each of a plurality of available SSD devices is ordered by a remaining life expectancy in an ascending order. Those of the plurality of hot data segments are matched with those of the plurality of hot data segments with those of the plurality of available SSD devices such that a hot data segment having a higher read/write ratio is provided to an SSD device having a smaller remaining life expectancy than another hot data segment having a lower read/write ratio.

摘要： A system and method implementable in a JAVA® application for providing C++ language friend-style access that grants JAVA® objects access to methods of another JAVA® object. The method comprises steps of: providing a method in the implementing JAVA object for determining the name of a JAVA object class that has called a method within the implementing JAVA object; comparing the JAVA object class name against a list of object names that have been granted access rights to the method in the implementing JAVA object; and, in response to the comparing, one of: enabling execution of the method of the implementing JAVA object upon determination that the calling object class is a member of the list, or, preventing execution of the method upon determination that the calling object is not a member of the list.
