Abstract: A method and system are provided for transferring data in a networked system between a local memory in a local system and a remote memory in a remote system. A RDMA request is received and a first buffer region is associated with a first transfer operation. The system determines whether a size of the first buffer region exceeds a maximum transfer size of the networked system. Portions of the second buffer region may be associated with the first transfer operation based on the determination of the size of the first buffer region. The system subsequently performs the first transfer operation.

Abstract: A computer system such as a server pipelines RNIC interface (RI) management/control operations such as memory registration operations to hide from network applications the latency in performing RDMA work requests caused in part by delays in processing the memory registration operations and the time required to execute the registration operations themselves. A separate QP-like structure, called a control QP (CQP), interfaces with a control processor (CP) to form a control path pipeline, separate from the transaction pipeline, which is designated to handle all control path traffic associated with the processing of RI control operations. This includes memory registration operations (MR OPs), as well as the creation and destruction of traditional QPs for processing RDMA transactions. Once the MR OP has been queued in the control path pipeline of the adapter, a pending bit is set which is associated with the MR OP.

Abstract: Device images, for example IDE mass storage device images, may be enabled and disabled without disrupting a host system. In one embodiment, the invention includes a memory device register to indicate the presence of a memory device to a computer system, a switch coupled to the memory device register to set the memory device register to indicate the presence of a memory device, and an external interface coupled to the switch to operate the switch.

Abstract: A flexible arrangement allows a single arrangement of Ethernet channel adapter (ECA) hardware functions to appear as needed to conform to various operating system deployment models. A PCI interface presents a logical model of virtual devices appropriate to the relevant operating system. Mapping parameters and values are associated with the packet streams to allow the packet streams to be properly processed according to the presented logical model and needed operations. Mapping occurs at both the host side and at the network side to allow the multiple operations of the ECA to be performed while still allowing proper delivery at each interface.

Abstract: In an embodiment, an apparatus is provided that may include an integrated circuit including switch circuitry to determine, at least in part, an action to be executed involving a packet. This determination may be based, at least in part, upon flow information determined, at least in part, from the packet, and packet processing policy information. The circuitry may examine the policy information to determine whether a previously-established packet processing policy has been established that corresponds, at least in part, to the flow information. If the circuitry determines, at least in part, that the policy has not been established and the packet is a first packet in a flow corresponding at least in part to the flow information, the switch circuitry may request that at least one switch control program module establish, at least in part, a new packet processing policy corresponding, at least in part, to the flow information.

The physical layer network device may be physically and electrically coupled to the cable connector receptacle. The physical layer network device may include a circuit board. The circuit board may be directly physically coupled to the receptacle. The circuit board also may be electrically coupled to the receptacle. Many alternatives, variations, and modifications are possible.

Abstract: In an embodiment, a method is provided. In an embodiment, the method provides determining that a message has been placed in a send buffer; and transferring the message to an application on a second virtual machine by bypassing use of an operating system to process the message by directly placing the message in an application memory space from which the application can retrieve the message.

Abstract: A video redirection system redirects an incoming video stream to a remote console. The video redirection system samples the video stream to generate a currently sampled frame comprising a plurality of tiles, and calculates a current hash value for each of the tiles. The video redirection system compresses the tile if the current hash value is different from a reference hash value locally stored inside the video redirection system. A difference in the hash value indicates that there is a change in the tile of the currently sampled frame from the corresponding tile of the previously sampled frame. Thus, it is no longer necessary to compare the currently sampled frame with a reference frame in the memory. Accordingly, the amount of memory access is reduced.

Abstract: According to one embodiment, an apparatus is disclosed. The apparatus includes a port having a plurality of lanes, a plurality of protocol engines. Each protocol engine is associated with one of the plurality of lanes, and processes tasks to be forwarded to a plurality of remote nodes. The apparatus also includes a first port task scheduler (PTS) to manage the tasks to be forwarded to the one or more of the plurality of protocol engines. The first PTS includes a register to indicate which of the plurality of protocol engines the first PTS is to support.

Abstract: In an embodiment, circuitry residing, at least in part, at a first network node may initiate, at least in part, replicating, at least in part, at the first node of a file space at a second network node, may detect, at least in part, modification at the second node of the file space, and may initiate, at least in part, corresponding modification at the first node of a replication of the file space. The circuitry also may generate, at least in part, an aggregated directory structure including, at least in part, the file space and another file space resident, at least in part, remotely from the second node. The directory structure may be provided, at least in part, to the second node prior, at least in part, to completion of the replicating, at least in part, at the first node of the file space.

Abstract: Devices, media, systems, and methods provide remote maintenance of a managed computer system through a remote computer. The remote computer is accessed by a CPU in the managed computer system as though it were a local IDE controller attached to a local IDE device. A peripheral device distinct from the CPU provides a set of virtual IDE device registers and an IDE controller to the CPU. The peripheral device receives data written to the set of virtual IDE device registers, and it transmits the data into a network, addressed for reception by the remote computer. The remote computer receives the data, interprets it, and performs operations upon a mirror set of device data. The remote computer then transmits its response across the network to the peripheral device. The peripheral device communicates the response to the CPU in a fashion identical to a physical IDE controller attached to a physical IDE device.
