  • Patent number: 7870413
    Abstract: A clocking scheme is provided to synchronize system clock across plural independent SMP (Symmetric Multi-Processing) domains of the multi-processor system. Each of the SMP domains is connected with another through an interconnection board and two or more identical connectors. The clocking scheme includes a clock source, a SPLL (Select Phase-Locked Loop) and a clock buffer on each of the SMP domains to provide a dedicated base clock. A self-clock path is used to send the base clock from the clock source to the SPLL on the same SMP domain, and on the other hand one or more base clock is sent through a distribution-clock path to another SPLL. The distribution-clock path and the self-clock path will have equal lengths, making the base clock pass through the two connectors or the same connector twice to achieve the similar electrical characteristics and balance the skew or propagation delay.

  • Publication number: 20090024724
    Abstract: A system is provided to assign IP (Internet Protocol) addresses to plural management modules under different IP modes. The system management modules are configured in a computing system that is integrated in a single chassis. All the system management modules are connected through a first management network to be assigned with a static IP address or a DHCP. Besides, a secondary system management network is used for each of the management modules to facilitate the assignment of pre-assigned private IP addresses based on the board IDs of the management modules. When DHCP mode is selected, IP configuration will be performed automatically. Namely in DHCP mode, even if the system is disconnected from the external network, the system management can be done through the system management network with the pre-assigned private IP address.

  • Publication number: 20080281475
    Abstract: A fan control architecture is provided for controlling system fan(s) on a computing system that has multiple nodes, a system management network and a fan control module. On each of the nodes a management module is configured to collect system information thereon. In a main fan control scheme, a system management node controls the system fan through the fan control module according to the temperature data sent back from the management module of the other nodes through the system management network. The fan control scheme includes redundant path(s) connected between all the nodes and the fan control module to send high-temperature signals to the fan control module directly. In the case that a threshold high temperature is reached, the fan control module will set the system fan at a predetermined high speed according to the high-temperature signals.

  • Publication number: 20080043769
    Abstract: A system management architecture is provided to manage plural compute nodes in a clustering system. Each of the compute nodes basically includes a BMC (Baseboard Management Controller) for local management. Among the compute nodes, a preset one has its BMC connecting with a management network switch through an extra network interface for clustering/system management. A first network interface, which is usually used to connect with the management network switch for communicating with other compute nodes, is utilized for the BMC of the preset compute node to connect with an external management host. A chipset on the preset compute node also connects with the external management host through a system I/O bus and the first network interface. On the preset compute node a operating system provides Network Address Translation service to allow the external management host to access each of the compute nodes.
