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.

Claims20

Dependent claims

A method, comprising:

managing, by a software agent at a smart network interface card of a cloud omputing environment, a set of one or more active network paths according to a performance threshold associated with the set of one or more active network paths, the set of one or more active network paths being associated with a set of one or more established network connections between the smart network interface card and a storage data plane of the cloud computing environment;
monitoring, by the software agent executing at the smart network interface card, network traffic utilizing the set of one or more established network connections associated with the set of one or more active network paths;
determining, by the software agent executing at the smart network interface card, that the network traffic utilizing the set of one or more established network connections associated with the set of one or more active network paths has met a condition relating to the performance threshold associated with the set of one or more active network paths;
and
responsive to determining that the network traffic has met the condition relating to the performance threshold associated with the set of one or more active network paths, modifying, by the software agent executing at the smart network interface card, a number of established network connections between the smart network interface card and the storage data plane of the cloud computing environment, the number of established network connections corresponding to the set of one or more active network paths.

2 more elements

memory configured to store instructions;
and
one or more processors configured to execute the instructions to at least:
execute, by a software agent executing at a smart network interface card of a cloud computing environment, the software agent being configured to manage a set of one or ore active network paths according to a performance threshold associated with the set of one or more active network paths, the set of one or more active network paths being associated with a set of one or more established network connections between the smart network interface card and a storage data plane of the cloud computing environment;
monitor, by the software agent executing at the smart network interface card, network traffic utilizing the set of one or more established network connections associated with the set of one or more active network paths;
determine, by the software agent executing at the smart network interface card, that the network traffic utilizing the set of one or more established network connections associated with the set of one or more active network paths has met a condition relating to the performance threshold associated with the set of one or more active network paths;
and
responsive to determining that the network traffic has met the condition relating to the performance threshold associated with the set of one or more active network paths, modify, by the software agent executing at the smart network interface card, a number of established network connections between the smart network interface card and the storage data plane of the cloud computing environment, the number of established network connections corresponding to the set of one or more active paths.
