A processor-based device having a plurality of memory cartridges secured within a chassis by a lever system. The processor-based device comprises an indication system to indicate memory system operating conditions. Each memory cartridge has a protective assembly to protect memory elements within the memory cartridge when the memory cartridge is removed from the processor-based device. The processor-based device is operable such that at least one memory cartridge may be removed from the processor-based device without affecting operation of the processor-based device.
摘要:
A computer system with an Intelligent Input/Output architecture having a scheme for hiding at least a portion of peripheral devices. The computer system comprises at least one host processor for executing a host operating system, the host processor disposed on a host bus, a first input/output (I/O) bus operably coupled to the host bus via a host-to-bus bridge, and a plurality of peripheral devices operably connected to the I/O bus for transferring data in I/O transactions. A masking module is provided for rendering at least a portion of the plurality of peripheral devices hidden from the host operating system and host processors. The masking module is configured upon system initialization and the contents of the module are used in blocking IDSEL signals associated with the portion of peripheral devices subordinated to an I/O processor.

A memory storage system includes a motherboard, a first memory card, and second memory card. The motherboard has a first and second electrical connector. The first memory card has a plurality of electrical connections coupled to the first electrical connector on the motherboard. The first memory card is adapted to receive a plurality of data signals over the first electrical connector and store the data signals in a first preselected pattern. A second memory card has a plurality of electrical connections coupled to the second electrical connector on the motherboard. The second memory card is adapted to receive a plurality of data signals over the second electrical connector and store the data signals in a second preselected pattern, different from the first preselected pattern.
摘要:
Apparatus, and an associated method, for determining the level of power supply redundancy in a modular computer system. Determination of the level of power supply redundancy is made dynamically, during on-line operation of the computer system. Reconfiguration of the computer system, such as to increase the load which must be powered by modular power supply components, or removal or addition of power supply components to form portions of the computer system cause initiation of a new determination of the level of power supply redundancy. Indications of inadequate levels of power supply redundancy are provided to a user of the computer system so that corrective action can be taken.
摘要:
A system and an associated method which provides a dual interrupt mechanism to designate the occurrence and termination of an event. In a computer system employing redundant components, upon removal of a defective redundant unit within the computer system, a first interrupt is generated to signal the absence of the unit. Polling or other system monitoring of the status of the absent unit is masked or disabled, thereby eliminating unnecessary polling for the missing unit. Upon replacement of the unit, a second interrupt alerts the computer system of the event termination and cancels the polling mask.

An apparatus controls a signal that indicates to a plug-in component board that it is to be connected to a 64-bit data path in a computer system. The apparatus comprises a timing circuit for receiving a reset signal and providing first and second complementary logical signals in response thereto. A selection switch receives the first and second logical signals as well as a control signal and outputs a third signal as determined by the logical level of the reset signal. A method involves generating first and second complementary signals from a reset signal, selecting between the first complementary signal and a control signal, and outputting a third signal, the logical value of the third signal being determined by the logical value of at least one of the reset signal and the control signal.
摘要:
A method of testing on-line and spare memory is disclosed. Such memory may currently store in-use data at some addresses. The testing is initiated upon an occurrence of a pre-selected condition. An address range is determined that excludes at least the addresses currently storing functional data. The address range is subjected to a test pattern, and errors in the address range are reported.
