摘要： Provided are a method, system, and program for configuring shared devices over a fabric. A module in a first processing complex configures a first part of a fabric enabling communication with a set of devices accessible through the first part of the fabric. The module detects a located device accessible through a second part of the fabric, wherein a second processing complex is designated to configure the second part of the fabric and the located device. The module determines whether the second processing complex is available in response to detecting the uninitialized device. The module passes to a device driver in the first processing complex an uninitialized property for the located device. The device driver requests the module to configure the second part of the fabric to enable access to the located device over the second part of the fabric in response to determining that the located device has the uninitialized property.

摘要： An apparatus and method allows processing sequenced records across multiple network connections. A “logical connection” is defined to include one or more network connections. Each message is assigned a sequence number that allows the messages to be ordered on the other end according to sequence number, regardless of which network connection in the logical connection is used to transfer the message. By defining messages, sequencing those messages, and transferring the messages over multiple network connections, the throughput and performance of networked computer systems are substantially increased.

摘要： A method, apparatus and computer program product implement InfiniBand (IB) network topology simplification. A Subnet Manager (SM) of an IB subnet sends a subnet discovery request to each switch requesting the number of ports that are attached to the switch. Each of the switches and target channel adapters (TCAs) within the IB subnet includes a Subnet Management Agent (SMA). The Subnet Management Agent (SMA) of the receiving switch responds to the SM indicating a sufficient number of ports on the switch to support at least one port for each TCA. Each TCA supports at least two local IDs (LIDs).

摘要： A method and system for communication in a system area network (SAN) data processing system are described. The SAN includes a plurality of interconnected nodes that each have at least one port for communication. To avoid communication-induced errors that may arise, for example, if multiple nodes share the same node ID, the port of a node in the SAN is marked as “fenced” to prevent transmission of packets of a first traffic type while permitting transmission of packets of a second traffic type. The marking of the port may be recorded, for example, in a configuration register of the port. While the port is fenced, only packets of other than the first traffic type are routed via the port. In one preferred embodiment, the second traffic type represents SAN configuration traffic, and the first traffic type represents non-configuration traffic. In this preferred embodiment, the marking of the port may be removed following communication of configuration traffic utilized to negotiate unique node ID throughout the SAN.
