International Classification:

G06F 15/00
G06F 17/50

US Classification:

702183, 705 29

Abstract:

Use of parts in products is managed to minimize the use of parts that will reach their end of life prior to the products for which those parts are usable. To manage use of a part, end of life data for the part is estimated and compared to the actual or projected end of life data of a product for which the part is to be used or is used. If the comparison indicates that the part will reach its end of life prior to the product, then various factors are considered to determine whether the part is to be used in the product. The factors include cost, scheduling, alternate part availability, redesign options and/or other factors.

International Classification:

G06F 11/00

US Classification:

714 6, 711114

Abstract:

Systems, methods, and computer program products for enhancing tolerance of data loss in a disk array system have been provided. Systems include a redundant array of independent disks (RAID) storage system including an array of hard disk devices (HDDs) organized in a two dimensional structure of rows and columns of HDDs. The system includes a full stride logically partitioning the rows and columns of HDDs into rows and columns of elements, the full stride including an element from each HDD in the rows and columns of HDDs, each element in the full stride residing on a physically independent HDD. Each element has an element type, wherein a first element type is a data element and a second element type is a checksum element. The system further includes a row checksum element calculated as a checksum of all data elements in a row of the full stride, and a column checksum element calculated as a checksum of all data elements in a column of the full stride, wherein the row checksum element calculation and the column checksum element calculation intersect at a single data element. The system also includes a device adapter for controlling access to the array of HDDs, the device adapter calculating the row checksum element and the column checksum element, the row checksum element and the column checksum element utilized to correct one or more failures in the array of HDDs.

US Classification:

714 62, 714 61, 714 622, 714 42

Abstract:

A system and method for providing a high fault tolerant memory system. The system includes a memory system having a memory controller, a plurality of memory modules and a mechanism. The plurality of memory modules are in communication with the memory controller and with a plurality of memory devices. The plurality of memory devices include at least one spare memory device for providing memory device sparing capability. The mechanism is for detecting that one of the memory modules has failed possibly coincident with a memory device failure on an other of the memory modules. The mechanism allows the memory system to continue to run unimpaired in the presence of the memory module failure and the possible memory device failure.

Abstract:

A system and method for error correction and detection in a memory system. The system includes a memory controller, a plurality of memory modules and a mechanism. The memory modules are in communication with the memory controller and with a plurality of memory devices. The mechanism detects that one of the memory modules has failed possibly coincident with a memory device failure on an other of the memory modules. The mechanism allows the memory system to continue to run unimpaired in the presence of the memory module failure and the memory device failure.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 12/00

US Classification:

711 5

Abstract:

A memory system with high availability is provided. The memory system includes multiple memory channels. Each memory channel includes at least one memory module with memory devices organized as partial ranks coupled to memory device bus segments. Each partial rank includes a subset of the memory devices accessible as a subchannel on a subset of the memory device bus segments. The memory system also includes a memory controller in communication with the multiple memory channels. The memory controller distributes an access request across the memory channels to access a full rank. The full rank includes at least two of the partial ranks on separate memory channels. Partial ranks on a common memory module can be concurrently accessed. The memory modules can use at least one checksum memory device as a dedicated checksum memory device or a shared checksum memory device between at least two of the concurrently accessible partial ranks.

Abstract:

Methods, systems, and computer program products are provided for dynamic selective memory mirroring in solid state devices. An amount of memory is reserved. Sections of the memory to select for mirroring in the reserved memory are dynamically determined. The selected sections of the memory contain critical areas. The selected sections of the memory are mirrored in the reserved memory.

James O'Connor - Brooklyn NY, US

International Classification:

G06Q 99/00

US Classification:

705 13, 705 11, 705 711

Abstract:

An embodiment of the disclosed technology is an in-taxi customer selection system. The selection system is placed in a plurality of taxis in the form of a device which includes a touch-screen display map of a surrounding location of each taxi. An indicator of at least one future rider desiring a taxi is exhibited anonymously on each display map. The indicator exhibits only a location, and thus, lacks destination data or information about the potential rider other than his or her location of pickup. In this manner, all picked up riders are anonymous to the driver and discrimination against the rider is actually less than in the prior art, since the appearance of the rider cannot be judged before the ride is accepted. Sensors within the touch-screen display receive a selection of an indicator on one of the display maps from a driver of one of the taxis using this system. The selected indicator is then removed from all other display maps, if shown on any at the time, and the driver is sent a confirmation of said selection.
