摘要： In a communications channel coupled to multiple duplicated subsystems, a method, interposer and program product are provided for verifying integrity of subsystem responses. Within the communications channel, a first checksum is calculated with receipt of a first response from a first subsystem responsive to a common request, and a second checksum is calculated for a second response of a second subsystem received responsive to the common request. The first checksum and the second checksum are compared, and if matching, only one of the first response and the second response is forwarded from the communications channel as the response to the common request, with the other of the first response and the second response being discarded by the communications channel.

摘要： 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.
