摘要： A system and method for establishing multiple connections using a private data field of a communication management protocol is provided. With the present invention, a Service ID identifies a specific consumer and the private data field contains a list of connection attributes for each connection that is to be established. An active side requests a connection and the passive side replies to the connection request. The active side sends the passive side a connection establishment request. This connection establishment request includes a Service ID which identifies a passive side process associated with a service. This connection establishment request also includes communication attributes of one or more connected services and datagram services associated with the Service ID. The passive passes the connection request to a process associated with the service. If the passive side process does not wish to carry out the service, a negative reply message is returned to the active side. If the passive side process does wish to carry out the service, a positive reply is returned to the active side and the reply includes the communication attributes for the connection and unreliable services associated with the Service ID used in the connection establishment request.

摘要： A method for enabling a Q_key that is tamper proof from applications on a distributed computer system to protect selected network operations is provided. Applications and an operating system (OS) execute on the end nodes and each may access various network resources. In the invention, the network resources are configured for selective access by particular applications or OS.In a preferred embodiment, a control bit of a Q_key, which allows applications to authenticate their use of particular communication resources, i.e., the send and receive queues, is reserved and utilized to signal whether a particular application is allowed access to the resources. Setting the control bit to 0 allows the Q_key to be set by an application directly. When the control bit is set to 1, the Q_key cannot be set by an application and can only be set using a privileged operation performed only by the OS.

摘要： A method in a node for managing authorized attempts to access the node. A packet is received from a source, wherein the packet includes a first key. A determination is made as to whether the first key matches a second key for the node. The packet is dropped without a response to the source if the first key does not match the second key. Information from the packet is stored in response to this absence of a match. The information is sent to a selected recipient in response to a selected event, which may be, for example, either immediately or in response to polling to see if the information is present.

摘要： A method and system for efficiently merging subnets having individual subnet managers (SM) into a single network with one master SM. During discovery and configuration of a subnet, a subnet manager creates a Subnet Management Database (SMDB) representative of the subnet components being managed. Each subnet manager contains an independent SMDB. When two or more subnets are linked/connected together to form a single network, a single one of the subnet managers is selected as the master subnet manager and all the subnets' SMDBs must be merged. An SMDB record labeling mechanism is utilized to differentiate among components from the different subnets that may have the same parameter values, such as protection keys (P_keys) and re-assign individual parameters to create a single SMDB of uniquely defined components.

摘要： Apparatus and method for virtualizing a queue pair space to minimize time-wait impacts. Virtual queue pairs are allocated from a virtual queue pair pool of a node to connections between the node and other nodes. The connection is established between a physical queue pair of the node and physical queue pairs of other nodes. From the viewpoint of the other nodes, they are communicating with the present node using the virtual queue pair and not the physical queue pair for the present node. By using the virtual queue pairs, the same physical queue pair may accommodate multiple connections with other nodes simultaneously. Moreover, when a connection is torn down, the virtual queue pair is placed in a time-wait state rather than the physical queue pair. As a result, the physical queue pair may continue to function while the virtual queue pair is in the time-wait state.

摘要： A method and apparatus to perform network fabric management is provided. The method and apparatus provide a mechanism by which modifications to components of the network fabric may be made without tearing down existing connections. The apparatus and method facilitate such fabric management by placing send queues in a send queue drain state and suspending the send queues affected by changes to the network fabric while the modifications are being made. Once the modifications are complete, the send queues are place back into an operational state.

摘要： An open format storage subsystem and method are provided. The storage subsystem and method include at least one host endnode, at least one processing unit endnode, and at least one storage endnode. These endnodes are partitioned according to partition tables assigned to the ports of the endnodes and partition keys assigned to queue pairs of the ports. Based on these partition keys, partitions in the storage subsystem are designated. In this way, certain endnodes may be designated as being able to communicate with only certain other ones of the endnodes. Because of the partitioning mechanism of the present invention, an open format storage subsystem is formulated such that the types of endnodes in the storage subsystem are not limited to vendor specific units. This enhances the ability to add and remove units from the storage subsystem by removing the limitations typically found in closed storage subsystems.

摘要： A method and apparatus for pausing a send queue while preventing sympathy error from propagating through a SAN fabric system is provided. The method and apparatus place a send work queue in an error state, i.e. pauses the send work queue, when a reliable data error occurs in the send work queue but does not place any other work queues in an error state. In this way, the send queue experiencing the error is not able to send any further messages until error recovery is performed. However, other work queues continue to be able to send and/or receive messages. Once error recovery is performed, the send work queue that was placed in the error state is returned to a working state and is able to continue to send messages. In addition, the send queue that was in the error state will send the messages that it attempted to send at the time of the error. The messages sent will continue from a last known point at which the send work queue was operating properly. Other features and advantages of the present invention will be described in, or will become apparent to those of ordinary skill in the art in view of, the following description of the preferred embodiments.
摘要翻译：提供了一种用于暂停发送队列同时防止同情错误通过SAN结构体系传播的方法和装置。当在发送工作队列中发生可靠的数据错误但不将任何其他工作队列置于错误状态时，该方法和装置将发送工作队列置于错误状态，即暂停发送工作队列。以这种方式，遇到错误的发送队列不能发送任何进一步的消息，直到执行错误恢复。然而，其他工作队列仍然能够发送和/或接收消息。一旦执行错误恢复，发生在错误状态的发送工作队列将返回到工作状态，并能够继续发送消息。另外，处于错误状态的发送队列将发送错误时尝试发送的消息。发送的消息将从发送工作队列正常运行的最后一个已知点继续。考虑到优选实施例的以下描述，本发明的其它特征和优点将在本领域普通技术人员中描述或将变得显而易见。

摘要： An apparatus and method for an advanced multiplexing technique to allow a single host to support multiple Internet Protocol (IP) queue pairs with little or no overhead are provided. With the apparatus and method, after a queue pair is created, Internet Protocol filter attributes and values are set up for the queue pair through value added features to the standard InfiniBand “QP Modify” method. The IP filters are used during normal operations to determine which queue pair is associated with an incoming packet. During normal operations, when a channel adapter receives an Internet Protocol (IP) over InfiniBand (IB) packet, it uses one or more of several fields in the packet's transport and/or network header to determine which queue pair shall receive the packet. Thus, the host channel adapter uses the IP filters to route incoming packets to the appropriate queue pair and thereby allow more than one queue pair to be used to support IP.
