Abstract: Enhanced methods, systems, and techniques for facilitating item exchange are provided. Example embodiments provide an Exchange Facilitator System (“EFS”), which facilitates listing and sale of items offered for sale by sellers via one or more third-party item exchange systems. In some embodiments, the EFS obtains information about an item offered for sale by a seller, and automatically generates a listing for the item, based on the information about the item and information about other items sold on one or more item exchange systems. The EFS may then electronically provide the generated item listing to an item exchange system, and further manage the progress and sale of the item via the item exchange system. This abstract is provided to comply with rules requiring an abstract, and is submitted with the intention that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: An input/output processor provides device virtualization “on-board” through the use of a dedicated IO cache memory. A computer system includes at least one host processor and associated main memory each with access to a system bus. Each input/output processor is also connected to the system bus through an expansion bus. IO adapters within the input/output processor each connect at least one storage device to the expansion bus. Also connected to the expansion bus is the cache memory and a control logic. The control logic receives a data transfer request from a requesting host processor. The data transfer request is mapped to a cache device object. The cache device object has associated data maintained in the cache memory. If any storage device is required for the data transfer, the data transfer request is mapped to the storage device capable of servicing the request. A location in cache memory is determined based on the mapped cache device object.
