Abstract: Efficient and highly-scalable network solutions are provided that each utilize deployment units based on Clos networks, but in an environment such as a data center of Internet Protocol-based network. Each of the deployment units can include multiple stages of devices, where connections between devices are only made between stages and the deployment units are highly connected. In some embodiments, the level of connectivity between two stages can be reduced, providing available connections to add edge switches and additional host connections while keeping the same number of between-tier connections. In some embodiments, where deployment units (or other network groups) can be used at different levels to connect other deployment units, the edges of the deployment units can be fused to reduce the number of devices per host connection.

Abstract: A system and method for preventing dependency problems, such as deadlocks, within network-based computing service workflows, such as workflows that occur within computing assets that provide network-based computing services. The system and method creates a remedial workflow or action for the computing services to address deadlocks or other blocking conditions within the services which may occur should the underlying computing assets need to be restarted, rebooted or sequentially execute and reach a problematic operational state. The system and method will determine the reliance of each computing service upon the functionality of one or more other network-based computing services and structure the remedial workflow accordingly. Other aspects of the disclosure are described in the detailed description, figures, and claims.

Abstract: The deployment and scaling of a network of electronic devices can be improved by utilizing one or more network transpose boxes. Each transpose box can include a number of connectors and a meshing useful for implementing a specific network topology. When connecting devices of different tiers in the network, each device need only be connected to at least one of the connectors on the transpose box. The meshing of the transpose box can cause each device to be connected to any or all of the devices in the other tier as dictated by the network topology. When changing network topologies or scaling the network, additional devices can be added to available connectors on an existing transpose box, or new or additional transpose boxes can be deployed in order to handle the change with minimal cabling effort.

Abstract: High-speed processing of packets to, and from, a virtualization environment can be provided while utilizing segmentation offload and other such functionality of commodity hardware. Virtualization information can be added to extension portions of protocol headers, for example, such that the payload portion is unchanged and, when physical address information is added to a frame, a frame can be processed using commodity hardware. In some embodiments, the virtualization information can be hashed and added to the payload or stream at, or relative to, various segmentation boundaries, such that the virtualization or additional header information will only be added to a subset of the packets once segmented, thereby reducing the necessary overhead. Further, the hashing of the information can allow for reconstruction of the virtualization information upon desegmentation even in the event of packet loss.

Abstract: Approaches are described for updating code and/or instructions in one or more computing devices. In particular, various embodiments provide approaches for updating the microcode of one or more processors of a computing device without requiring a restart of the computing device and without disrupting the various components (e.g., applications, virtual machines, etc.) executing on the computing device. The microcode updates can be performed on host computing devices deployed in a resource center of a service provider (e.g., cloud computing service provider), where each host computing device may be executing a hypervisor hosting multiple guest virtual machines (or other guest applications) for the customers of the service provider.

Abstract: Efficient and highly-scalable network solutions are provided that utilize incremental scaling of switches, and devices connected to those switches, in an environment such as a data center. Embodiments may utilize multiple tiers of switches. Sets of switches in two different tiers may be initially connected to each other utilizing multiple connections. As network capacity needs within the computing environment increase, additional switches may be added to tiers. To connect the added switches to the switch network, the redundant connections may be utilized. Moving connections from one switch to another switch can free up ports to connect added switches in one of the tiers of switches to the switch network. The tiers of switches can be based on Clos networks, where the tiers of switches are fully connected, or other high radix or fat tree topologies that include oversubscription between tiers.

Abstract: Approaches for automatically backing up data from volatile memory to persistent storage in the event of a power outage, blackout or other such failure are described. The approaches can be implemented on a computing device that includes a motherboard, central processing unit (CPU) a main power source, volatile memory (e.g., random access memory (RAM)), an alternate power source and circuitry (e.g., a specialized application-specific integrated circuit (ASIC)) for performing the backup of volatile memory to a persistent storage device. In the event of a power failure of the main power source, the alternate power source is configured to supply power to the specialized ASIC for backing up the data in the volatile memory. For example, when power failure is detected, the ASIC can read the data from the DIMM socket using power supplied from the alternate power source and write that data to a persistent storage device.
