摘要： In one embodiment, an apparatus includes a processor configured for operation in a control plane in a distributed virtual switch in communication with a plurality of virtual machines each having a virtual interface. The processor is operable to identify other control planes in the distributed virtual switch, assign a virtual interface identifier to one of the virtual interfaces, receive a configuration for the virtual interface, and share the configuration with the other control planes in the distributed virtual switch. The virtual interface identifier provides a unique identifier for the virtual interface across all of the control planes. The apparatus further includes memory for storing the configuration of the virtual interface. A method for operating a network device associated with a control in the distributed virtual switch is also disclosed.

摘要： An apparatus for offloading network, block and file functions from an operating system comprises a network interface (118A,118B) coupled to a network for receiving packet flows; one or more processors each having one or more processor cores; a computer- readable medium carrying one or more operating systems and an input/output networking stack (110) which are hosted in one or more of the processor cores. The networking stack is shared among the operating systems (104A,104B). The networking stack comprises instructions which when executed cause receiving a request for data transfer from one of the operating systems at internal network, block and file system interfaces (112,114,116), and permitting data to be transferred between the internal interfaces and a plurality of external interfaces (118A-118D) by preventing the operating systems from performing the data transfer and performing the data transfer on behalf of the operating systems.
摘要翻译：用于从操作系统卸载网络，块和文件功能的设备包括：网络接口（118A，118B），其耦合到网络以用于接收分组流; 一个或多个处理器，每个处理器具有一个或多个处理器核; 携带一个或多个操作系统的计算机可读介质以及托管在一个或多个处理器内核中的输入/输出网络栈（110）。网络栈在操作系统（104A，104B）之间共享。联网堆栈包括指令，所述指令在被执行时导致从内部网络，块和文件系统接口（112,114,116）处的操作系统中的一个接收数据传输的请求，并且允许数据在内部接口和多个外部接口（118A-118D），防止操作系统执行数据传输并代表操作系统执行数据传输。

摘要： The present invention defines a new protocol for communicating with an offload engine that provides Transmission Control Protocol ("TCP") termination over a Fibre Channel ("FC") fabric. The offload engine terminates all protocols up to and including TCP and performs the processing associated with those layers. The offload protocol guarantees delivery and is encapsulated within FCP-formatted frames. Thus, the TCP streams are reliably passed to the host. Additionally, using this scheme, the offload engine can provide parsing of the TCP stream to further assist the host. The present invention also provides network devices (and components thereof) that are configured to perform the foregoing methods. The invention further defines how network attached storage ("NAS") protocol data units ("PDUs") are parsed and delivered.
摘要翻译：本发明定义了一种用于与卸载引擎进行通信的新协议，该卸载引擎通过光纤通道（“FC”）结构提供传输控制协议（“TCP”）终止。卸载引擎终止直到并包括TCP的所有协议，并执行与这些层相关联的处理。卸载协议保证传送，并封装在FCP格式的帧中。因此，TCP流可靠地传递到主机。另外，使用该方案，卸载引擎可以提供TCP流的解析以进一步协助主机。本发明还提供了被配置为执行前述方法的网络设备（及其组件）。本发明进一步定义如何解析和传送网络连接存储（“NAS”）协议数据单元（“PDU”）。

摘要： The subject technology addresses the need in the art for improving provisioning and booting of virtual machines in a cloud computing environment. Different versions of boot volume images may be shared in a storage repository accessible by one or more host computers. When a virtual machine is created, a shared boot volume image, including confirmation information for the virtual machine, may be selected for booting the virtual machine. Over time, newer version(s) of boot volume images may be stored in the storage repository and new virtual machine(s) may use the newer version of the boot volume image for booting.
