Abstract: The disclosed systems, methods and computer readable media relate to managing Non-Volatile Memory Express (NVMe) over Transmission Control Protocol (TCP) (NVMeOTCP) connections between a smart network interface card (smartNIC) and a block storage data plane (BSDP) of a cloud computing environment. A software agent (“agent”) executing at the smartNIC may manage a number of network paths (active and, in some cases, passive network paths). The agent may monitor the network traffic (e.g., input/output operations (IOPS)) through the paths (e.g., using established NVMeOTCP connections corresponding to the paths). If a condition is met relating to a performance threshold associated with the monitored paths, the agent may increase or decrease the number established NVMeOTCP connections to match real time network conditions.

Abstract: Techniques disclosed herein include receiving a request to perform an upgrade. The upgrade can comprise changes to firmware or software of the network interface card. Input/Output (I/O) traffic can be monitored on one or more paths between the network interface card and a storage device. The paths can have a path capacity comprising a bandwidth of Input/Output traffic. The spare Input/Output traffic capacity can be calculated based at least in part on the Input/Output traffic and the path capacity. Whether to remove a path can be determined based at least in part on the spare Input/Output traffic capacity. The upgrade can be performed with the path halted in accordance with a determination to remove the path. The upgrade can be performed with the path included in accordance with a determination to not remove the path.

Abstract: The disclosed systems, methods, and computer readable media relate to managing persistent memory within a smart network interface card (smartNIC) of a cloud-computing environment, or at storage device of the host instance on which the smartNIC operates and to which the smartNIC has access. The smartNIC may be configured with various modes that enable passthrough of input/output operations to or from non-volatile remote storage (e.g., a block storage data plane volume) or storage of at least some of the data corresponding to the input/output operations within the persistent memory managed by the smartNIC. The smartNIC may be configured to select a storage location for data between a pool of candidate storage including the persistent storage managed by the smartNIC or the non-volatile remote storage. These techniques improve communications between the smartNIC and the non-volatile remote storage and reduce the risk of network jitters and overall network latency.

Abstract: A network virtualization device receives a storage request from a compute instance executed by a host machine separate from the network virtualization device, the storage request comprising data to be stored. Responsive to receiving the storage request, the network virtualization device divides the data to be stored into a set of one or more data stripes. For a first data stripe in the set of data stripes, the network virtualization device determines, from a plurality of extent servers, a first extent server to which the first data stripe is to be sent for storing the first data stripe, transmits the first data stripe to the first extent server, wherein the first extent server stores the first data stipe to a first physical storage device, and receives, from the first extent server, an acknowledgement confirming that the first data stripe was stored.

Abstract: The techniques disclosed herein enable a system to configure a confidential virtual resource unit by provisioning a security component to a tenant's virtual resource unit. The system creates multiple different virtual trust layers within the confidential virtual resource unit. This creation effectively defines security boundaries between the virtual trust layers. The virtual trust layers are associated with different privileges, such that a higher privileged virtual trust layer is provided with more privileges compared to a lower privileged virtual trust layer. In one example, a lower privileged virtual trust layer may include basic virtual resource components (e.g., drivers, applications, processes, functions, workloads executing within a guest operating system) and a higher privileged virtual trust layer is the location to which a virtual security component is provisioned by the system.
