摘要:
Methods, apparatus and systems for data storage including initiating a destaging process in a storage system for destaging data from a cache to a mass storage device. Upon inputting a standby command to the storage system to inhibit the destaging of the data in a specified range, the destaging of the data in the specified range from the cache to the mass storage device is inhibited.
摘要:
A method for use of a physical data storage medium, the method including receiving a first read request for data stored in any of a plurality of storage sub-units on a physical data storage medium, and decrypting the requested data if an indicator associated with the requested data storage sub-unit indicates that data in the requested storage sub-unit is encrypted.

Method, device and computer program product for determining a characteristic of an identifiable component. The method includes: receiving identification information representative of an identity of components that belong to a group of components, determining at least one characteristic of an identifiable component in response to the received identification information, and performing at least one characteristic responsive operation. The device includes an identifiable component and a component characteristic determiner. The component characteristic determiner is adapted to receive identification information representative of an identity of components that belong to a group of components and to determine at least one characteristic of the identifiable component in response to a relationship between the received identification information and reference identification information. The device is adapted to perform at least one characteristic responsive information.
摘要:
Logging and storage transactions in a database are directed to a single storage server. A modification of a database record is written only once to a log record on the storage server. Subsequently, the storage server interprets the database log records, and modifies the database storage accordingly. The number of bytes written to storage is potentially reduced by fifty percent as compared to writing the log record and then writing the modified database record to the storage server.

摘要:
Method, device and computer program product for support of maintaining a system. The method includes: evaluating a current system state and detecting a first lattice element corresponding to the current system state; locating at least one state improvement path, within a lattice that represents states of the system, between the first lattice element and a second lattice element representative of a target system state; determining, for at least one state improvement path, rules that should be satisfied in order to reach the system target state; and determining how to fulfill the rules associated with at least one state improvement path.
摘要:
A method for software processing includes extracting from software code under test respective items of meta-information pertaining to elements of the software code and receiving respective quality data regarding the elements of software code. The quality data and meta-information are processed in a computer so as to assign respective metrics to the items of the meta-information responsively to the quality data regarding the elements of the software code to which the items pertain. At least some of the meta-information is presented to a user in accordance with the assigned metrics.
摘要:
A method for managing a group of targets is provided. The method includes: receiving a request to update a x'th generation copy of a data entity, where x is a positive integer. Then applying an update function responsive to x such as to update a first sub-group of targets. Then receiving a request to read a y'th generation copy of the data entity and (iv) applying a retrieve function responsive to y such as to search for the y'th generation copy of the data entity in a second sub-group of targets. The first and second sub-groups intersect only once and only if y does not exceed x.
摘要:
A method for modeling a test space is provided. The method comprises defining a coverage model including one or more variables, wherein respective values for the variables are assigned, one or more definitions of value properties for said variables with assigned values, and one or more restrictions that limit combination of variable values that are legal for the model, wherein at least one of said restrictions is defined using at least one value property.
