A jumper including a connecting face, a light-emitting face, and a light pipe extending from the connecting face to the light-emitting face is provided. The light pipe is operable to transmit a light from a provided computer hardware from the connecting face to the light-emitting face responsive to the jumper forming a circuit with the provided computer hardware. A method for fabricating a jumper is also provided. The method includes forming a plurality of receptacles on a connecting face of the jumper and incorporating a light pipe into the jumper such that the light pipe extends from the connecting face of the jumper to a light-emitting face of the jumper. A method for providing jumper installation feedback is further provided. The method includes mounting a jumper on a provided computer hardware and transmitting a light through the jumper responsive to the jumper forming a circuit with the provided computer hardware.

A method, system, and program product supporting dynamic configuring of a multi-node computer. The system includes a scalability management module directly coupled to each node in the multi-node computer. The scalability management module sets and maintains configuration parameters for the multi-node computer, wherein if one of the nodes is removed from the multi-node computer, a hot-spare node can be dynamically configured to replace the removed node without having to reconfiguring or physically reconnect the remaining nodes

Basic server resources may be extended by the completion of a Capacity on Demand (CoD) Agreement. The CoD Agreement provides authorization to the server for activation of inactive resources. A Power On Self Test (POST) works in conjunction with a system management interrupt, a memory unit, and a plurality of Peripheral Component Interconnect (PCI) host bridges to provide for on demand additions of input and output adapters. The adapters may be added during various phases of operation and may be hot pluggable.

Methods and arrangements to dynamically modify the number of processors active in a multi-node data processing system. are contemplated. Embodiments include transformations, code, state machines or other logic to change the portion of BIOS that a processor loads on power-on. In some embodiments, a signal sent over a GPIO pin may flip an address line to the portion of the BIO that a processor loads on power-on. In some embodiments, a service processor may set a GPIO or non-volatile RAM value. The portion of BIOS controlling the powering-up of the processor may read the value and branch depending upon the value. Embodiments also include transformations, code, state machines or other logic to determine the state of a dynamically activated processor. In some embodiments, a processor may read from a local scratch register to determine if it has been dynamically activated. If so, embodiments may then clear the scratch register and put the processor to sleep. Embodiments may then update the tables which describe the resources available to the processor.
摘要:
A method and system for allowing nodes in a multi-node computer to be appropriated by a master node in the multi-node computer. The node to be appropriated is suspended into an ACPI S3 Sleep State, causing current system operations state information to be stored in a backup memory in the appropriated node. The master node then populated a primary memory in the appropriated node with OS and other information required to join a partition that includes the master node. When the master node no longer wishes to use the appropriated node, the backup memory in the appropriated node is mirrored back into the primary memory. When the appropriated node “wakes up” from the S3 state, it continues executing software commands where it left off, without knowing anything that had happened after going into the S3 state.
摘要:
A method and system for booting up multiple PCI peripheral devices, such that the number of bootable PCI peripheral devices is not limited by the amount of computer system memory that is dedicated to storing executable boot code for the peripheral devices. The executable boot code is stored on a Read Only Memory (ROM) on each peripheral device. When a new PCI peripheral device begins to boot up, a check for available memory space in a ROM scan memory address space is performed. If there is not enough available room in the ROM scan memory address space for the new device's executable boot code, then a ROM scan detection logic pages an image of another peripheral device's executable boot code out of the ROM scan memory address space before storing the new device's executable boot code into the ROM scan memory address space.
摘要:
A method and system for emulating a hardware Internet Small Computer System Interface (iSCSI) Host Bus Adapter (HBA) without risking an interruption of communication between a computer and a remote secondary storage device is presented. During normal operations, a (hardware emulating) software iSCSI HBA drives a Network Interface Card (NIC) to afford communication between the computer and the remote secondary storage. If an operating system (OS) anomaly occurs in the computer, the NIC is normally disconnected by the OS. To maintain communication between the computer and the secondary storage device if such an event occurs, a failover network device is called up by the computer's System Management Memory (SMM) Basic Input Output System (BIOS), which allows uninterrupted communication to continue between the computer and remote secondary storage device.

An apparatus, system, and method are disclosed for automatically verifying access to a multipathed target at boot time. The apparatus is provided with a logic unit containing a plurality of modules configured to functionally execute the necessary steps of identifying a plurality of paths to a target device, automatically selecting one of the plurality of paths to the target device, and verifying access on at least one path to the target device. Beneficially, the disclosed embodiments of the apparatus, system, and method reduce false errors during the boot cycle, improve reliability of the multipathed network, simplify traffic load balancing, and provide for topology mapping for troubleshooting and network metrics. The disclosed embodiments provide a means for verifying multipathed targets automatically, without requiring user assistance, intervention, or interaction.

A method and system are disclosed to enable and control power reduction in a blade/chassis system. A “maximum power reduction” attribute is stored in the VPD of the blade (or can otherwise be input to or retrieved or calculated by the management entity). The management module of the chassis in which the blades and power supplies are located uses this information to manage the power reduction of blades when the system is operating in an over-subscription mode and a power supply fails. If throttling is required, the system knows the amount of power reduction available for each blade and controls the throttling by spreading it out among the blades in the system so that, ideally, no blade will cease operation altogether.
