摘要： A method and system for providing a plurality of host systems shared access to data files from a file server. The method includes monitoring a control file for updates, the control file located within a corresponding host directory located within the file server; receiving a request for access to a data file stored on the file server, the access request being written to the control file, the access request including a requested data file operation; performing the requested data file operation in response to the control file being updated with the access request; creating a status file in the host directory in which the requested data file operation was performed upon completion of the requested data file operation; writing status data in the status file, the status data including a result of the performance of the requested data file operation; and allowing access to the host directory in which the requested data file operation was performed in response to the status data being written to the status file.

摘要： Systems and methods for performing data input/output (I/O) operations using a computer network communications link are described. A method may include assigning a block of virtual addresses for usage with at least one computer network communications link. The method may also include registering the entire block of virtual addresses prior to an operating system partition performing I/O operations using the at least one computer network communications link, wherein registering comprises setting a plurality of virtual page frame numbers of the block of virtual addresses to point to distinct pages of physical memory. In some embodiments, one or more I/O operations may be performed using the at least one computer network communications link and the registered block of virtual addresses.
