REMOTE DIRECT ATTACHED MULTIPLE STORAGE FUNCTION STORAGE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18222420 titled 'REMOTE DIRECT ATTACHED MULTIPLE STORAGE FUNCTION STORAGE DEVICE

Simplified Explanation

The patent application describes a multiple function storage device that includes an enclosure, a storage device, and a bridging device.

  • The storage device has a connector to receive messages from a host, a physical function (PF) and a virtual function (VF) exposed via the connector, storage for data, and a controller to manage writing and reading data.
  • The bridging device has an embedded network interface controller (eNIC) to receive messages from the host, write and read buffers, a bridge circuit to translate messages, and a root port to identify the storage device and transmit messages to the VF.
  • The bridging device is configured to map the host to the VF.


Original Abstract Submitted

A multiple function storage device is disclosed. The multiple function storage device may include an enclosure, a storage device associated with the enclosure, and an bridging device associated with the enclosure. The storage device may include a connector to receive a first message using a first protocol originating at a host, a physical function (PF) and a virtual function (VF) exposed by the storage device via the connector, storage for data relating to the first message, and a controller to manage writing a write data to the storage and reading a read data from the storage. The bridging device may include an embedded network interface controller (eNIC) to receive a second message using a second protocol from the host, a write buffer to store the write data to be written to the storage device by the host, a read buffer to store the read data to be read from the storage device for the host, a bridge circuit to translate the second message using the second protocol into the first message using the first protocol, and a root port to identify the storage device and to transmit the first message to the VF. The bridging device may be configured to map the host to the VF.
