摘要： A network device routes data packets by storing the packets in a switching memory as a function of a destination address of the packet. The switching memory comprises switching memory queues that are mapped to ports of the device. A header of a received packet is examined to determine the network destination address to which it is to be routed, and a destination queue is assigned to the packet based on the destination address. Thereafter, the packet is divided into cells, and the cells are written to contiguous locations in the destination queue.

摘要： A hybrid server and multi-layer switch system architecture, referred to hereinafter as the Enterprise Fabric (EF) architecture, forms the basis for a number of Enterprise Server (ES) chassis embodiments. Each ES embodiment generally includes one or more Processor Memory Modules (PMMs, each generally having one or more symmetric multiprocessor complexes), one or more Network Modules, and a System Control Module (SCM). The SCM includes a cellified switching-fabric core (SF) and a System Intelligence Module (SIM). Each PMM has one or more resident Virtual IO Controller (VIOC) adapters. Each VIOC is a specialized I/O controller that includes embedded layer-2 forwarding and filtering functions and tightly couples the PMM to the SF. Thus the layer-2 switch functionality within the ES chassis is distributed over all of the SCM, NM, and PMM modules. Through the use of VIOC/VNIC device drivers, host operating system software (Host O/S) running on the PMMs is presented with a plurality of Virtual Network Interface Cards (VNICs). In some embodiments, each VNIC behaves as a high-performance Ethernet interface at the full disposal of the Host O/S. In other embodiments, at least some of the VNICs behave as high-performance Fibre Channel Host Bus Adapters.

摘要： A system can comprise an I/O circuitry, a processor, reconfigurable circuitry, an array of flash storage devices, and a serial interconnect network that is coupled to transfer data between the I/O circuitry, the processor, the reconfigurable circuitry and the flash storage devices. The processor can be configured to designate an interconnect address space for use in communication over the interconnect network among the I/O circuitry, the processor, the reconfigurable circuitry and the flash storage devices. The reconfigurable circuitry can be configured to translate data addresses during transfers of data between the I/O circuitry and the array of flash storage devices. A method to access an array of flash storage devices that are coupled to I/O circuitry over a serial interconnect network can comprise using reconfigurable circuitry to capture data during transfers of data over the serial interconnect network.

摘要： A Cost-Reduced Enterprise Server (CRES) system includes a flexible resource-efficient server having a plurality of Processor Memory Boards (PMBs) coupled to an Input/Output Module (IOM). The IOM provides all networking and storage interfaces for the server. The IOM is implemented as a field-replaceable pluggable module, and thus all Input/Output (I/O) capabilities or resources of a CRES system may be upgraded via replacement of the IOM. Each PMB is dividable into a pair of Symmetric MultiProcessor (SMP) complexes, and each complex is coupled to a respective portion of the I/O resources provided by the IOM. Each portion of the IOM provides a pair of I/O daughter-module connectors compatible with standard I/O interfaces, such as Peripheral Component Interconnect (PCI)-X and PCI-Express. One or more CRES systems may be coupled to one or more Enterprise Server (ES) systems to form a multi-chassis server managed collectively as one or more provisioned servers.

摘要： Routing systems and methods are provided having various strategies for optimizing and evaluating possible routes for netlist connections. In one embodiment, a data structure or matrix provides cost related data weighted to evaluate the impact proposed a connection or segment will have upon an attribute of interest such as, for example, speed, manufacturability or noise tolerance. This cost information can be related to terrain costs as well as shape costs to provide multidimensional cost information for connections. Processing such higher information cost data is made more efficient with an additive process that is less demanding than a computationally intensive iterative multiplication process. Various methods are also disclosed for shifting and adjusting routing grids to improve use of available space or reduce run time in routing. In another embodiment, a parallel processing scheme is used to process multiple regions on multiple processors simultaneously without creating conflicts, that could arise, for example, when two processors try to route a trace on the same gridpoint.

摘要： A client-server relational database system, wherein data from the client computer is encrypted by the client computer and hosted by the server computer, the encrypted data is operated upon by the server computer, using one or more operators selected from a group of operators comprising: (a) inequality logic operators, (b) aggregation operators, and (c) wildcard matching operators, to produce an intermediate results set, the intermediate results set is sent from the server computer to the client computer, and the intermediate results set is decrypted and filtered by the client computer to produce actual results. The group of operators is limited because the encrypted results set, when decrypted, includes inaccuracies therein. The client computer applies a set of correction procedures to the decrypted results set to remove the inaccuracies therein.

摘要： A multi-level cache and method for operation thereof is presented for processing multiple cache system accesses simultaneously and handling the interactions between the queues of the cache levels. The cache unit includes a non-blocking cache receiving data access requests from a functional unit in a processor, and a miss queue storing entries corresponding to data access requests not serviced by the non-blocking cache. A victim queue stores entries of the non-blocking cache which have been evicted from the non-blocking cache, while a write queue buffers write requests into the non-blocking cache. Controller logic is provided for controlling interaction between the miss queue and the victim queue. Controller logic is also provided for controlling interaction between the miss queue and the write queue. Controller logic is also provided for controlling interaction between the victim queue and the miss queue for processing cache misses.
