摘要： Network virtualization can be provided via network I/O interfaces, which may be partially or fully aware of the virtualization. Network virtualization can be reflected in the use of a first header and an additional header(s) for a data frame. A partially-aware transmit example can gather together data frame components, including its additional header(s), via a work queue entry. A fully-aware transmit example can refer to a transmit-side table to gather its additional header(s) and can track the state of its additional header(s) stored in a cache. A partially-aware receive example can handle an additional header(s), e.g., by writing it to host-memory. A fully-aware receive example can determine values from multiple headers (including its additional header(s)) to further determine where to write a data payload to host-memory. The examples can relieve a host's hypervisor from performing all the network virtualization processing. The fully-aware examples can incorporate JOY techniques.

摘要： The collection of performance data at multiple servers in a SAN and forwarding that data to a centralized server for analysis is disclosed. Remote agents and a central server application collect specific interesting negative event data to enable a picture of the operational health of the SAN to be determined. The agents are placed in servers having HBAs acting as initiators. The agents interact with the HBAs through a driver stack to collect event data. Because of the initiator function they perform, HBAs have visibility to parts of the network that other entities do not have access to, and thus are ideal locations for gathering event data. A SAN diagnostics manager then pulls the collected data from each agent so that a “picture” of the SAN can be developed. In addition to collecting initiator data, the agents also collect errors and performance data from the OS of the servers.

摘要： Embodiments of the invention relate to performing network communications according to an existing protocol by using frames that are larger than those usually allowed by the existing protocol. Thus, embodiments of the present invention provide for an extension of the existing protocol which allows for the use of larger frames. The larger frames may result from the use of larger payloads and their size may be defined in terms of the payload size. Embodiments provide for use of various negotiation and initialization mechanisms of the existing protocol with additional modifications to allow for the negotiation of the use of larger frames. These modifications may provide for end to end negotiation of a larger frame or payload size. Some embodiments ensure that the negotiations are performed in such a manner that devices that feature the improvements of the present invention can communicate with devices that do not feature these improvements.
摘要翻译： 本发明的实施例涉及通过使用比现有协议通常允许的帧大的帧来执行根据现有协议的网络通信。 因此，本发明的实施例提供了允许使用较大帧的现有协议的扩展。 较大的帧可能由于使用较大的有效载荷而产生，并且它们的大小可以根据有效负载大小来定义。 实施例提供了使用现有协议的各种协商和初始化机制的附加修改以允许协商使用较大的帧。 这些修改可以提供更大的帧或有效载荷大小的端到端协商。 一些实施例确保以这样的方式执行协商，使得本发明的改进特征的设备可以与不具有这些改进的设备通信。

摘要： In various embodiments, the present invention provides virtual disk formatting by intermediate devices including: (1) a storage shelf router and the storage shelf in which the storage-shelf is included, to external computing entities, such as disk-array controllers and host computers; (2) an I/O controller; and (3) a storage-bridge device. Additional embodiments of the present invention enhance virtual formatting by using additional padding, in a dual-abstraction method, to efficiently align virtual-block reads with underlying device blocks. Yet additional embodiments of the present invention allow for tracking and correcting device blocks corrupted during READ-MODIFY operations that occur during virtual-block WRITE operations. Various intermediate devices may employ two or more of the virtual formatting, dual abstraction, and corrupted-device-block tracking methods.

摘要： Disclosed herein are methods and apparatus for accelerating RoCE packet sequence transmission and reducing processing latency in received RoCE packets. Under the disclosed method, the RoCE protocol stack and RDMA verbs are implemented partially in the host software and partially in the adapter hardware, thereby providing a better balance between simplifying the adapter configuration and maximizing the host processing efficiency. Particularly, the adapter implemented with partial RoCE offload is able to perform a few major functionalities under the RoCE protocol, such as offloading a complete RoCE packet sequence for transmission, building individual packets out of the RoCE packet sequence and performing Invariant CRC calculation, insertion, validation and removal thereof.

摘要： An apparatus and method is disclosed for reducing the computational overhead incurred by a host processor during packet processing and improving network performance by adding additional functionality to a Network Interface Controller (NIC). Under certain circumstances the NIC coalesces multiple receive packets into a single coalesced packet stored within a coalesce buffer in host memory. The coalesced packet includes an Ethernet header, a coalesced Internet Protocol (IP) header, a coalesced Transmission Control Protocol (TCP) header, and a coalesced TCP payload containing the TCP payloads of the multiple receive packets. By coalescing received packets into fewer larger coalesced packets within the host memory, the host software needed to process a receive packet will be invoked less often, meaning that less processor overhead is incurred in the host.
摘要翻译： 公开了一种用于在分组处理期间减少由主处理器产生的计算开销并通过向网络接口控制器（NIC）添加附加功能来提高网络性能的装置和方法。 在某些情况下，NIC将多个接收分组合并成存储在主机存储器中的合并缓冲器内的单个合并分组。 合并的分组包括以太网报头，合并的因特网协议（IP）报头，合并的传输控制协议（TCP）报头，以及包含多个接收分组的TCP有效载荷的合并的TCP有效载荷。 通过将接收到的数据包合并到主机存储器内较少的较大的合并数据包中，处理接收数据包所需的主机软件将被更少地调用，这意味着在主机中会产生较少的处理器开销。

摘要： Embodiments of the present invention allow for address scaling of existing addresses in a FC, FCoE, CEE or other type of network. More specifically, subaddresses can be used in conjunction with existing addresses, so that a combination of a subaddress and existing address can identify an addressable entity. Thus, multiple entities can be share a single existing address and be distinguished among each other by way of their respective subaddresses. Some embodiments of the invention allow for use of the inventive subaddressing scheme in conjunction with devices or network elements (e.g., gateways, switches, etc.) that may not be subaddressing aware. Further embodiments allow for the multiple distinct devices to communicate with a single Fiber Channel switching element through a single port by using N_Port_ID Virtualization.
