Abstract: Method and apparatus to provide a data replication system to receive a data transfer request from a first component at a transmitter module in a continuous data replication system having a production site and a backup site, the production site having a transmitter module and a transmitter credit mechanism, the transmitter module to transmit data over a network for replication in the backup site, detect a high-load condition at the transmitter module, and modify a flow of credits from the transmitter credit mechanism to the first component to reduce or stop data flow to the transmitter module.

Abstract: A customizable integrated circuit including a substrate, a plurality of logic units formed on the substrate and a plurality of metal routing layers formed on the substrate for interconnecting the plurality of logic units. The plurality of metal routing layers includes a first routing layer including a plurality of elongate conductors extending generally in a given direction, a second routing layer including a plurality of transversely extending conductors, each adapted for interconnecting a termination of one of the plurality of elongate conductors to a beginning of another one of the plurality of elongate conductors and at least a third routing layer, including a plurality of local routing conductors, a plurality of customizable connections between pairs of the plurality of elongate conductors via individual ones of the plurality of transversely extending conductors and customizable connections between individual elongate conductors and a plurality of individual local routing conductors.

Abstract: A method for receiving messages containing data conveyed over a network, using a network adapter coupled to a computing device having a system memory associated therewith. At least one queue of descriptors is generated in the system memory, each such descriptor indicating a disposition of the data contained in the messages to be received over the network. At least one of the descriptors is prefetched from the at least one queue in the system memory to a cache memory in the network adapter. When one of the messages is received at the network adapter, the adapter processes the at least one of the received messages so as to cause the data contained therein to be distributed in accordance with the at least one prefetched descriptor in the cache memory.
