US Patent:

7308603, Dec 11, 2007

Filed:

Oct 18, 2004

Appl. No.:

10/968548

Inventors:

Brian L. Carver - Raleigh NC, US
William G. Pagan - Durham NC, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 11/00

US Classification:

714 8, 714723

Abstract:

Method and system for reducing memory faults for computer systems. In one aspect, a notification is received that indicates that a single bit error has been detected in a portion of memory of the computer system. A service program is used to isolate the portion of the memory that includes the detected single bit error by allocating the portion of memory to itself, such that the portion of memory may no longer be accessed for data reading or writing by programs running on the computer system.

Appl. No.:

11/867270

Inventors:

Henry Gaines McMillan - Raleigh NC, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H01R 13/62

US Classification:

439310

Abstract:

An apparatus and method for connecting servers within a rack-mounted server system. In one embodiment, a plurality of servers are positioned in respective bays of a rack. The bays generally constrain adjacent servers in a generally fixed spacing and in face-to-face alignment. A first server is moved within its bay relative to a second server until a connector on the first server is aligned with a mating connector on the second server. Alignment of the two mating connectors is detected by a position sensor, such as an LED-photodiode pair. A signal from the position sensor causes or at least allows the first and second connectors to be moved toward one another, either using a motor or a hand-actuated mechanism, to provide power and data communication between the servers. Once the connection is established, data is optionally transmitted via the optical sensor.

International Classification:

G06F 11/00

US Classification:

714 6, 711220

Abstract:

An apparatus, system, and method are disclosed for redirecting an instruction pointer to recovery software instructions. A load module copies a first and second process to memory locations addressed by a first and second base address. An instruction pointer module addresses a memory location with an address comprising a pointer base address set to the first base address and an offset. A pointer modification module modifies the pointer base address from the first base address to the second base address in response to a read error to redirect the instruction pointer module to a memory location of the second process.
