Server node interconnect devices and methods

A method and apparatus for managing a virtual address to physical address translation utilize a subpage level fault detecting and access. The method and apparatus may also use an additional subpage and page store Non-Volatile Store (NVS). The method and apparatus determines whether a page fault occurs or whether a subpage fault occurs to effect an address translation and also operates such that if a subpage fault had occurred, a subpage is loaded corresponding to the fault from a NVS to a DRAM, such as DRAM or any other suitable volatile memory historically referred to as main memory. The method and apparatus, if a page fault has occurred, determines if a page fault has occurred without operating system assistance and is a hardware page fault detection system that loads a page corresponding to the fault from NVS to DRAM.

Systems and methods for input/output virtualization

A fabric interconnect system may provide a data path between nodes and/or processing elements within an interconnection fabric. Identifiers may be assigned to particular components associated with the interconnection fabric. These identifiers may uniquely identify the particular components, and may indicate a path between a root node and a particular component. In some embodiments, the identifiers include turn counts and turn values that specify a turn-based bath from the root node to a particular component. One or more identifier acceptance rules may be used in order to determine whether a given component should accept and store a particular identifier that the component receives. For example, a lower priority identifier may be discarded in favor of a higher priority identifier.

Multi-port system and method for routing a data element within an interconnection fabric

The invention utilizes a separate queue per output port as implemented in the traditional simple queuing schemes of the prior art. Further, it also uses the information found in the packet header to determine the output port and the next output port. Based on this information, it utilizes queues dedicated to congested flows, or 'Congested Flow' queues. When the switch determines that, based on the first output port and the second subsequent output port, a packet in the output queue is destined for a congested path, it sets the offending packet aside in a Congested Flow queue, thereby allowing other packets destined for the first output port to continue to be transmitted. In this way, the HOL blocking issue is addressed, without the need for a significantly increased number of output queues.
