Dual-access high-performance storage for BMC to host data sharing

A method comprising:

• connecting, via a switch, host input/output (“IO”) domain hardware to an end point port of a baseboard management controller (“BMC”), the host IO domain hardware, switch and BMC located in a computing device, the BMC comprising an external data connection;
• connecting, via the switch, a root port of the BMC to a storage device in the computing device while a connection between the host IO domain hardware is disconnected, via the switch, from the storage device;
• maintaining the connection between the root port of the BMC and the storage device while data from the external data connection is stored on the storage device;
• and
• in response to completion of storage of data from the external data connection, disconnecting, via the switch, the root port of the BMC from the storage device and connecting, via the switch, the host IO domain hardware to the storage device,
• wherein the host IO domain hardware comprises hardware circuits coupling a port of the host IO domain hardware to a processor, the port connected to the switch, or a processor comprising a port connected to the switch.

A computing device comprising:

• a storage device;
• host input/output (“IO”) domain hardware;
• a baseboard management controller (“BMC”) comprising an external data connection;
• and
• a switch comprising a connection to the host IO domain hardware, a connection to the storage device, a connection to a root port in the BMC, and a connection to an end point port of the BMC,
• wherein the BMC comprises a service processor and non-volatile computer readable storage media coupled to the service processor, the computer readable storage media comprising program code configured to:
• connect the host IO domain hardware to the end point port of the BMC;
• connect the root port of the BMC to the storage device and disconnect the host IO domain hardware from the storage device while uploading data from the external data connection for storage on the storage device;
• and
• connect the host IO domain hardware to the storage device and disconnect the root port of the BMC from the storage device while data to be stored on the storage device is not being uploaded from the external data connection, and
• wherein the host IO domain hardware comprises hardware circuits coupling a port of the host IO domain hardware to a processor, the port connected to the switch, or a processor comprising a port connected to the switch.
