摘要： A mechanism for offloading the management of send queues in a split socket stack environment, including efficient split socket queue flow control and TCP/IP retransmission support. As consumers initiate send operations, send work queue entries (SWQEs) are created by an Upper Layer Protocol (ULP) and written to the send work queue (SWQ). The Internet Protocol Suite Offload Engine (IPSOE) is notified of a new entry to the SWQ and it subsequently reads this entry that contains pointers to the data that is to be transmitted. After the data is transmitted and acknowledgments are received, the IPSOE creates a completion queue entry (CQE) that is written into the completion queue (CQ). After the CQE is written, the ULP subsequently processes the entry and removes it from the CQE, freeing up a space in both the SWQ and CQ. The number of entries available in the SWQ are monitored by the ULP so that it does not overwrite any valid entries. Likewise, the IPSOE monitors the number of entries available in the CQ, so as not overwrite the CQ. The flow control between the ULP and the IPSOE is credit based. The passing of CQ credits is the only explicit mechanism required to manage flow control of both the SWQ and the CQ between the ULP and the IPSOE.

摘要： A mechanism for offloading the management of receive queues in a split (e.g. split socket, split iSCSI, split DAFS) stack environment, including efficient queue flow control and TCP/IP retransmission support. An Upper Layer Protocol (ULP) creates receive work queues and completion queues that are utilized by an Internet Protocol Suite Offload Engine (IPSOE) and the ULP to transfer information and carry out send operations. As consumers initiate receive operations, receive work queue entries (RWQEs) are created by the ULP and written to the receive work queue (RWQ). The ISPOE is notified of a new entry to the RWQ and it subsequently reads this entry that contains pointers to the data that is to be received. After the data is received, the IPSOE creates a completion queue entry (CQE) that is written into the completion queue (CQ). After the CQE is written, the ULP subsequently processes the entry and removes it from the CQE, freeing up a space in both the RWQ and CQ. The number of entries available in the RWQ are monitored by the ULP so that it does not overwrite any valid entries. Likewise, the IPSOE monitors the number of entries available in the CQ, so as not overwrite the CQ.

摘要翻译： 一种用于卸载分裂（例如，分裂式插座，拆分式iSCSI，拆分式DAFS）堆栈环境中接收队列管理的机制，包括有效的队列流控制和TCP / IP重传支持。 上层协议（ULP）创建互联网协议套件卸载引擎（IPSOE）和ULP利用的接收工作队列和完成队列，以传输信息并执行发送操作。 当消费者开始接收操作时，接收工作队列条目（RWQE）由ULP创建并写入接收工作队列（RWQ）。 通知ISPOE对RWQ的新条目，并随后读取包含要接收的数据的指针的该条目。 接收到数据后，IPSOE创建写入完成队列（CQ）的完成队列条目（CQE）。 在编写CQE之后，ULP随后处理该条目并将其从CQE中移除，释放了RWQ和CQ两者中的空间。 RWQ中可用的条目数由ULP监视，以便它不会覆盖任何有效的条目。 同样，IPSOE监视CQ中可用条目的数量，以免覆盖CQ。

摘要： A method is provided for creating and managing tables for routing packets through an environment that includes multiple hosts and shared PCI switches and adapters. A Destination Identification (DID) field in the PBA is appended to a transaction packet dispatched through the PCI switches, wherein a particular DID is associated with a particular host or system image, and thus identifies the physical or virtual end point of its packet. In one embodiment, packets are routed through PCI switches in a distributed computer system comprising multiple root nodes, wherein each root node includes one or more hosts. The embodiment includes the step of creating a table or like data structure in a specified one of the switches. When a particular host of one of the root nodes becomes connected to the specified switch, a PCI Configuration Master (PCM), residing in one of the root nodes, is operated to enter a destination identifier or DID into the table. The DID is then appended as an address component, to packets directed through the specified switch from the particular host to one of the adapters. The destination identifier is also used to determine that a PCI packet, routed through the specified switch from one of the adapters, is intended for the particular root node.

摘要： A system, method, and computer program product that enables user space middleware or applications to pass I/O storage requests directly to a network attached storage device via a storage server that performs authentication are provided. A mechanism is provided for using a translation protection table (TPT) data structure, which may include a file name protection table (FNPT) and file extension protection table (FEPT), or logical volume protection table (LVPT), to control user space and out of user space Input/Output (I/O) operations. The storage server performs authentication of an application instance's request to open an operating system logical volume and, upon being authenticated, permits the application instance to submit I/O storage requests via the TPT to the opened OS logical volume. I/O storage requests are translated into storage commands using the TPT and the storage commands are encapsulated for transmission via one or more networks to the storage server.

摘要： The present invention provides a system, method, and computer program product that enables application instances to pass block mode storage requests directly to a physical I/O adapter without run-time involvement from the local operating system or hypervisor. Specifically, a mechanism for providing and using a linear block address (LBA) translation protection table (TPT) to control out of user space I/O operations is provided. In one aspect of the present invention, the LBATPT includes an adapter protection table that has entries for each portion of a storage device and a corresponding LBA table having entries for identifying the linear block addresses associated with an adapter protection table entry. Table entries are correlated with one another using an LBA table pointer. Adapter protection table entries are associated with application instances using a key instance.

摘要： A computer-implemented method, apparatus, and computer usable program code are disclosed for migrating a virtual adapter from a source physical adapter to a destination physical adapter in a data processing system where multiple host computer systems share multiple adapters and communicate with those adapters through a PCI switched-fabric bus. The virtual adapter is first caused to stop processing transactions. All in-flight transactions that are associated with the virtual adapter are then captured. The configuration information that defines the virtual adapter is moved from the source physical adapter to the destination physical adapter. The in-flight transactions are then restored to their original locations on the destination virtual adapter. The virtual adapter is then restarted on the destination physical adapter such that the virtual adapter begins processing transactions.

摘要： A computer-implemented method, apparatus, and computer program product are disclosed for routing error messages in a multiple host computer system environment to only those host computer systems that are affected by the error. The environment includes multiple host computer systems that share multiple devices utilizing a switched fabric. An error is detected in one of the devices. Routing tables that are stored in fabric devices in the fabric are used to identify ones of the host computer systems that are affected by the error. An error message that identifies the error is routed to only the identified ones of the host computer systems.

摘要： System and method for managing routing of data in a distributed computing system, such as a distributed computing system that uses PCI Express protocol to communicate over an I/O fabric. A physical tree that is indicative of a physical configuration of the distributed computing system is determined, and a virtual tree is created from the physical tree. The virtual tree is then modified to change an association between at least one source device and at least one target device in the virtual tree. A validation mechanism validates the changed association between the at least one source device and the at least one target device to enable routing of data from the at least one source device to the at least one target device.
