摘要:
A computer-implemented method for efficient data storage is provided. A first storage medium associates data stored on one or more data storage media with a unique identification value (ID) for the purpose of determining de-duplication status of the data. In response to receiving a request to read the data from a logical address, the first storage medium retrieves the data from a second storage medium based on the unique ID. In response to receiving a request to write the data to a logical address, the one or more data storage media store at least one copy of the data based on the de-duplication status of the data.

摘要:
A method for modifying executable logic code stored on a computing system is provided. The method comprises assessing a risk level associated with modifying a first code block and assessing an urgency level associated with modifying the first code block and then evaluating whether the first code block should be modified.

A method for initializing a memory area, the method includes: receiving a request to access a first memory sub area of a first memory area that comprises multiple memory sub areas; and initializing the first memory sub area if a first memory area initialization indicator differs from a first memory sub area initialization request indicator; wherein the first memory area initialization request indicator is a multiple bit variable indicative of a time of a last request to initialize the first memory area and the first memory sub area initialization indicator is a multiple bit variable indicative of a time of a request to initialize the first memory area that resulted in a last initialization of the first memory sub area.
摘要:
A method for evaluating a debugger script, the method includes: (i) receiving a debugger script that includes a first debugger breakpoint that is associated with a certain program line number; and determining a validity of the first debugger breakpoint in response to a comparison between expected content associated with the first debugger breakpoint and between an actual content of at least a portion of a certain program line group that comprises a certain program line identified by the certain program line number.
摘要:
A method for synchronizing data storage systems is provided. The method comprises designating a relationship between a first data storage system and a second data storage system, such that data stored in the first data storage system is copied to the second data storage system, in response to determining that the data stored in the first data storage system has been modified; receiving a first request to modify data stored in a first data block of a first storage volume in the first data storage system, wherein the data block is modified according to the first request; determining that the first data block has not been successfully synchronized when the modified data stored in the first data block is not copied to the second data storage system; and executing a process to retry synchronization of the first data block until synchronization of the first data block is successful, without suspending the relationship while the process is executed.
摘要:
Provided are a method, system, and program for accessing a resource. Requests are generated to access a resource in a first access mode and a second access mode. The requests are processed to access the resource in the second mode before processing at least one request to access the resource in the first access mode. The processing of the requests to access the resource in the first access mode is delayed for a time period after processing all the requests to access the resource in the second access mode in order to wait to receive a subsequent request to access the resource in the second access mode.
摘要:
A method for checking an alternative system test, the method includes: determining a relationship between (i) utilization of resources during an execution of a group of programs by a first system when operating in a non-testing mode and (ii) utilization of resources during an executive of an alternative system test by the alternative system; wherein the alternative system test comprises at least on program of the group of programs.
摘要:
A mechanism is provided for managing operations in a data storage system. A first storage controller monitors operation state information associated with a plurality of operation states stored in a data structure. The first storage controller detects a change in the operation state information. The change in the operation state information is in response to a managing entity updating the operation state information to a first operation state in the plurality of operation states in the data structure. Responsive to detecting the change in the operation state information, the first storage controller identifies a reference to a first operation associated with the first operation state updated by the managing entity. The first operation is one operation in a plurality of operations. The first storage controller performs the first operation associated with the first operation state.
摘要:
A method for improving performance in a storage system is provided. The method comprises receiving a request to destage a partial stride of data from a storage cache; reserving space for a full stride of data on one or more storage devices; allocating the partial stride of data to the reserved space; adding padding for unallocated blocks, wherein the unallocated blocks are reserved for future updates; and destaging the full stride of data to the storage devices, wherein the full stride of data comprises the allocated partial stride of data and the padded unallocated blocks.
