SYSTEM AND METHOD FOR EFFICIENT ACCESS FOR REMOTE STORAGE DEVICES

摘要

A network interface controller (NIC) for use in a server controlling a plurality of storage devices provides remote access to a plurality of clients each accessing one or more storage devices of the plurality of storage devices. The NIC is configured to receive from at least a client device an input/output (I/O) request for a storage device of the plurality of storage devices and store the I/O request in a secondary memory thereof. The I/O request is sent to the storage device and a response respective of the I/O request intended for the primary processing unit of the server is received by the NIC. The client device is sent an indication that the I/O request is completed. In some exemplary embodiments, the NIC determines if the client device has appropriate I/O permissions to access a specific data block.

1. A network interface controller (NIC) for use in a server controlling a plurality of storage devices, the NIC comprising:
a network interface configured to communicatively connect the NIC to a network comprising a client device and the server; a communication interface configured to communicatively connect the NIC to a primary processing unit of the server; a secondary processing unit; a first memory containing instructions for execution by the secondary processing unit; and a second memory; wherein the instructions, when executed by the secondary processing unit, configure the NIC to: receive, from the client device, an input/output (I/O) request for a storage device from among the plurality of storage devices; store the I/O request in the second memory; send the I/O request to the storage device; receive, from the storage device, a response respective of the I/O request intended for the primary processing unit; and send the client device an indication that the I/O request is completed.
