摘要： Disclosed are a method of and system for providing time synchronization among first and second computer systems, where each of the computer systems includes hardware, operating system software and a layer of microcode operating between said hardware and said software. The method comprises the steps of using the microcode of the first computer system to provide a first timestamp, using the microcode of the second computer system to provide a second timestamp and a third timestamp, and using the microcode of the first computer system to provide a fourth timestamp. The method comprises the further steps of using the first, second, third and fourth timestamps to determine a timing difference between the first and second computer systems, and adjusting the timing among said first and second computer systems on the basis of said determined timing difference. Preferably, the first and second computer systems are connected together by a point-to-point link; and the first timestamp is sent from the first computer system to the second computer system, and the second and third timestamps are sent from the second computer system to the first computer system over that point-to-point link.

摘要： A communication port of a communications interface of an information handling system comprises a plurality of virtual ports. A first command is issued to obtain information indicating a number of images of virtual ports supportable by the communications interface. A second command is then issued requesting the communications interface to virtualize the communication port. In response to the second command, one or more virtual switches are then configured to connect to the communication port, each virtual switch including a plurality of virtual ports, such that the one or more virtual switches are configured in a manner sufficient to support the number of images of virtual ports indicated by the obtained information. Thereafter, upon request via issuance of a third command, a logical link is established between one of the virtual ports of one of the virtual switches and a communicating element of the information handling system.

摘要： A processor node of a network is provided which includes one or more processors and a virtualized channel adapter. The virtualized channel adapter is operable to reference a table to determine whether a destination of the communication is supported by the virtualized channel adapter. When the destination is supported for routing via hardware, the virtualized channel adapter is operable to route the communication via hardware to at least one of a physical port and a logical port of the virtualized channel adapter. Otherwise, when the destination is not supported for routing via hardware, the virtualized channel adapter is operable to route the communication via firmware to a virtual port of the virtualized channel adapter. A corresponding method and a recording medium having information recorded thereon for performing such method are also provided herein.

摘要： A method and apparatus that provide connectivity in a computer network environment that includes a plurality of nodes, interface links and at least one central electronic complex divided into one or more physical and or virtual sub-environments. A first control program is provided in the central electronic complex in order to establish a first command process layer and a first transfer process layer within this first control program for handling data. The first command process layer is then linked to the first transfer process layer in this control program. A second control program is also provided in the central electronic complex in order to establish a second command process layer and a second transfer process layer within this second control program for handling data. The second command process layer is also linked to the second transfer layer in said second control program.
