Computing device and storage card

A storage card connected to a host, the storage card comprising:

• a processor configured to execute firmware;
• and
• a storage device,
• wherein the firmware includes:
• a host interface layer is configured to select a service path or a data path by parsing a non-volatile memory express (NVMe) request according to an NVMe protocol received from the host;
• a mini-Docker layer including an image handler configured to perform container image management based on a network packet included in the NVMe request, and an execution handler configured to execute a container based on the network packet;
• and
• an operating system (OS) feature layer incudes a network handler configured to, in response to selection of the service path, forward the network packet to the mini-Docker layer or the container, and forward a network request, generated in the container, for communicating with the host to the host interface layer.

A computer program stored in a non-transitory recording medium and configured to be executed by a computing device including a host and a storage card, the computer program causing the computing device to execute:

• setting a first internet protocol (IP) address and a second IP address to the host and the storage card, respectively;
• converting a first Ethernet packet, which includes an in-storage processing (ISP)-related request and is destined for the second IP address, into a first non-volatile memory express (NVMe) request according to an NVMe protocol;
• and
• forwarding the first NVMe request to an NVMe driver to transfer the first NVMe request to the storage card,
• wherein the converting the first Ethernet packet comprises:
• copying data of the first Ethernet packet to a kernel page;
• filling a physical region page (PRP) field of the first NVMe request with an address of the kernel page;
• and
• setting an operation code of the first NVMe request to a value indicating a transmit frame command.
