System and method for storage access input/output operations in a virtualized environment

A system for managing a data input/output operation of a virtual node comprising:

• a computer comprising a processor operatively coupled with a local memory and a network interface, configured to run a virtualized environment comprising the virtual node, and to run in the virtualized environment a software task configured to:
• receive a request of the virtual node for memory write of data stored in the local memory in a distant memory of a data storage network node operatively coupled with the computer through the network interface, the request comprising information related to at least one location of the data in the local memory;
• generate a first packet descriptor of a packet carrying a message according to a communication protocol between the host computer and the data storage network node, based on the request for memory write of the data, the first packet descriptor comprising a header of the message;
• generate at least one second packet descriptor of the packet based on the information related to the at least one location in the local memory of the data;
• and
• provide the first and second packet descriptors to the network interface for transmission of the message to the data storage network node.

A non-transitory computer-readable storage medium storing a computer program that, when executed, causes a system comprising a processor operatively coupled with a memory, to perform a method for method for managing a data input/output operation of a virtual node of a virtualized environment running on a host computer comprising a processor operatively coupled with a local memory, for memory write of data in a distant memory comprised in a data storage network node operatively coupled to the host computer through a communication network, the method comprising:

• receiving a request of the virtual node for memory write of the data, the request comprising information related to at least one location in the local memory of the data;
• generating a first packet descriptor of a packet carrying a message according to a communication protocol between the host computer and the data storage network node, based on the request for memory write of the data, the first packet descriptor comprising a header of the message;
• generating at least one second packet descriptor of the packet based on the information related to the at least one location in the local memory of the data;
• and providing the first and second packet descriptors to a network interface of the host computer for transmission of the message to the data storage network node.
