摘要： Devices and techniques for out-of-band platform tuning and configuration are described herein. A device can include a telemetry interface to a telemetry collection system and a network interface to network adapter hardware. The device can receive platform telemetry metrics from the telemetry collection system, and network adapter silicon hardware statistics over the network interface, to gather collected statistics. The device can apply a heuristic algorithm using the collected statistics to determine processing core workloads generated by operation of a plurality of software systems communicatively coupled to the device. The device can provide a reconfiguration message to instruct at least one software system to switch operations to a different processing core, responsive to detecting an overload state on at least one processing core, based on the processing core workloads. Other embodiments are also described.

摘要： Technologies for ensuring data integrity for multi-packet operations include a computing device and a remote computing device communicatively coupled via a network. The computing device is configured to perform a segmentation offload operation on an original network packet, compute a hash value on the payload of each segmented payload of the original network packet, and store the hash value and an indication into the segmented network packet that indicates the hash value is stored in the segmented network packet. The remote computing device is configured to extract the indication and the hash value from a received network packet in response to determining the indication indicates the hash value is stored in the segmented network packet, compute a hash value on the payload of received network packet, and determine an integrity of the payload based on a comparison of the extracted hash value and the computed hash value.

摘要： Methods and apparatus to recover a processor state during a system failure or security event are disclosed. An example apparatus to recover data includes a processor including a local memory and a system monitor in communication with the processor. The system monitor is to copy processor backup data to a non-volatile memory in response to a processor backup event. The processor backup data includes contents of the local memory.

摘要： Methods, apparatus and systems for effecting Virtual Machine (VM) platform communication loopback and enabling user initiated network port failover. Network communications in platforms employing VMs and having multiple network ports accessible to the VMs are configured to be routed such that communications between VMs in the platform are looped back within the platform, thus not require routing through an external switch. This is facilitated via an Intelligent Channel Bonding Driver that dynamically enforces inter-VM traffic to ensure internal loopback within the same physical port. In another aspect, a user is enabled to initiate failover of a network port on a platform employing a Virtual Machine Manager and a plurality of VMs, wherein updated configuration information is sent to disable Virtual Function (VF) drivers associated with the network port.

摘要翻译： 用于实现虚拟机（VM）平台通信环回和启用用户启动的网络端口故障转移的方法，设备和系统。 配置使用虚拟机并具有VM可访问的多个网络端口的平台中的网络通信被配置为路由，使得平台中的VM之间的通信环回到平台内，因此不需要通过外部交换机进行路由。 这通过智能通道绑定驱动程序来实现，该驱动程序动态地实施VM间流量，以确保同一物理端口内的内部环回。 在另一方面，用户能够启动使用虚拟机管理器和多个虚拟机的平台上的网络端口的故障转移，其中更新的配置信息被发送以禁用与网络端口相关联的虚拟功能（VF）驱动器。
