摘要： A hot spare boot circuit that automatically switches from a non-operational CPU to an operational CPU for powering up the computer system. In the multiprocessor computer system, a first CPU is designated to perform power on operations. If the first CPU fails, which is determined when a dead man counter in the hot spare boot circuit times out, the hot spare circuit ensures that the first CPU is in a disabled state. Next, the hot spare boot circuit identifies an operational second CPU, reinitializing certain ID information as necessary such that the second CPU can properly perform power on operations. The hot spare boot then awakens the second CPU, using a startup interprocessor interrupt in one embodiment, or simply negating the hard reset of the second CPU in a second embodiment. The second CPU then proceeds to perform the power on functions.

摘要： A wide link communicates information between a storage enclosure having plural storage devices and an information handling system by selectively configuring upstream and downstream paths of narrow links to communicate in the same direction. A link load analyzer detects predetermined conditions, such as over utilization or under utilization of narrow link capacity, which initiates a re-configuration of the direction of information through a path of a narrow link. A master link manager configures a narrow link path to manage communication of configuration information for one or more narrow link paths configured to communicate in a direction.

摘要： Redundant storage of information is provided by distributing storage functions between a RAID controller and switching device. The switching device multi-casts writes to storage devices and to the RAID controller. The RAID controller generates parity for the information and writes the parity to the storage devices in space reserved for parity by the switching device. Information is read from the storage devices through the switching device without action by the RAID controller.

摘要： A network communication device including port control circuitry for controlling packet flow between the ports of the device, where the port control circuitry includes a port manager that directs packets between the ports and port bonding circuitry that bonds two or more of the ports into a bonded port set. For each packet to be sent via the bonded port set, the port bonding circuitry selects one of the bonded ports for transmitting the packet. More than one bonded port set may be defined in a given communication device, and each bonded port set may include from two ports up to all the ports of the device, as long as each port is included in only one bonded port set. One or more port bonding registers are provided to identify which of the plurality of ports are bonded in each bonded port set. In one embodiment, the bonded ports are selected on a packet by packet basis so as to achieve a relatively even distribution of packets sent by each bonded port. In an alternative embodiment bonded ports are assigned to packet source identifiers so as to achieve a relatively even distribution of source identifiers among the bonded ports. If bonded ports are assigned to particular source identifiers, then the traffic is preferably monitored and the assignments are periodically adjusted to achieve even distribution of packet flow on the bonded link. The bonded ports may have different bandwidths, in which case traffic is distributed on a proportionate basis.

摘要： Certain ones of a plurality of SAS hard disk drives are assigned to different SAS zones using a SAS zoning expander(s). A processor and SAS RAID controller have access to only those SAS hard disk drives assigned to the same zone(s) as the processor and SAS RAID controller. Each SAS RAID controller determines when a RAID hard disk drive in its zone fails, and then notifies the RAID hard disk drive failure to a service enclosure processor (SEP) of the SAS zoning expander. The SEP re-allocates an available hot-spare hard disk drive to the zone of the failed RAID hard disk drive. When the SAS RAID controller detects that a functional hard disk drive is now available in its zone, the RAID image is rebuilt using the zone reassigned hot-spare hard disk drive that then becomes one of the RAID hard disk drives of that zone.
