Systems and methods for enabling value added services for extensible storage devices over a network via nvme controller

A system to support operations on data transmitted with virtualized remote storages, comprising:

• an NVMe access engine running on the physical NVMe controller, which in operation, is configured to
• present one or more logical volumes mapped to a plurality of remote storage devices to one or more virtual machines (VMs) running on a host as if they were local storage volumes;
• receive instructions for one or more read and/or write operations issued by the VMs on the logical volumes mapped to the remote storage devices;
• a non-volatile memory express (NVMe) storage proxy engine running on a physical NVMe controller, which in operation, is configured to:
• create and map said logical volumes in the NVMe namespaces to the remote storage devices accessible via the NVMe controller over a network;
• perform one or more operations on the data to be written to and/or read from the remote storage devices over a network by the NVMe controller for security, integrity, compression, and efficient transmission of the data.

A computer-implemented method to support metering of data transmission with virtualized remote storages via a non-volatile memory express (NVMe) controller, comprising:

• creating and mapping one or more logical volumes in one or more NVMe namespaces to a plurality of remote storage devices accessible via the NVMe controller over a network;
• presenting the NVMe namespaces of the logical volumes to one or more virtual machines (VMs) running on a host as if they were local storage volumes;
• receiving instructions for one or more read and/or write operations issued by the VMs on the logical volumes mapped to the remote storage devices;
• monitoring and metering information on number of the read and/or write operations and/or data being transmitted by the read and/or write operations;
• utilizing the metered information on the data being transmitted by the read and/or write operations to determine resources consumed by the VMs for billing based on dynamic usage by the VMs and to maintain one or more promised service-level agreements (SLAs).
