Appl. No.:

11/539027

Inventors:

Tara Astigarraga - Tucson AZ, US
William E. Atherton - Hillsborough NC, US
Michael E. Browne - Staatsburg NY, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 12/00

US Classification:

702182

Abstract:

Disclosed are a method, electronic device, and computer readable medium for determining an end-of-life stage of the flash memory. The method includes detecting at least one life cycle event associated with a flash memory residing on an electronic device. A counter that is associated with the life cycle event is then incremented. Based on the counter, a total number of occurrences for the one life cycle event is determined. The total number of occurrences for the at least one given threshold is also determined. A current life cycle stage of the flash memory is identified based at least in part on determining if the total number of occurrences exceeds at least one given threshold. The life cycle stage is associated with the at least one given threshold. A user is then notified of the life cycle state of the flash memory.

US Classification:

714723, 714815, 714 31, 714 8, 714719, 714710

Abstract:

Method and system for repairing memory failure in a computer system in one aspect determines one or more test patterns and time duration for testing the new memory unit that replaced a failed memory unit. The test pattern is written to the new memory unit and read from the new memory unit. The read pattern is compared to the test pattern that was used to write. If the read test pattern and the written test pattern doe not match, a further repair action is taken. If they match, writing and reading of the test pattern repeats until the time duration for testing expires. The new memory unit may be configured as available for use when the write and read test completes successfully for the testing time duration.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 12/16

US Classification:

711162, 711E12103

Abstract:

A method can include identifying a storage area in the storage system for access control, assigning a switching criterion to modify allowable access to the identified storage area, where the identified storage area supports pre-staging of provisioned data, and blocking a select access attempt to the identified storage area as a function of the switching criterion.

Abstract:

Disclosed are a method, information processing system, and computer readable medium for resource recovery. The method comprises associating at least one bit with at least one block of memory. The bit denotes a borrow status for the block of memory. The bit is set for resource recovery. A resource recovery event is detected and in response to the bit being enabled for resource recovery, the block of memory is borrowed for a given duration of time. The block is borrowed to temporarily store information associated with the resource recovery there into until the information is written to persistent storage.

US Classification:

711135, 711E12054, 711E12022

Abstract:

A memory management method is disclosed. In response to a process running in a first memory and the first memory becoming constrained by demands from another process, information in the first memory is paged out to a second memory. In response to a request to further run the process, the information from the second memory is paged into a read cache and then into the first memory, while a copy of the information is left the read cache. In response to the information in the first memory then being updated and the copy of the information in the read cache now becoming stale, the now stale copy of the information in the read cache is checked for and purged, and indication is provided that the read cache has been purged.

US Classification:

711135, 711E12022

Abstract:

Disclosed are a method, system and computer program for purging data in a data storage system comprising a plurality of hosts one or more data storage devices and a controller, the controller including a cache. In accordance with the present invention, a communication interface is implemented between operating systems (OS) and the storage controller, of a multi-host data storage system, to signal the storage controller when the host is being shutdown. When the storage controller gets the signal, the controller purges the controller cache of any pages belonging to that host and puts those pages back into the free pool.
