Abstract

Claims (31)

1 . A device, comprising:

a physical interface to a host machine, the physical interface supporting at least a first transport protocol and a second transport protocol for communicating between the device and the host machine;

a circuit to identify a configuration of the host machine, the configuration including the first transport protocol intended to be used by the host machine to communicate with the device;

a self-configuration logic to configure the physical interface to lock the physical interface to the first transport protocol responsive to the configuration; and

a writing logic to write information by the device,

wherein the device is installed in the host machine, and

wherein the information written to the device includes a device incompatibility between the device and the host machine.

2 . A device according to claim 1 , wherein the first transport protocol and the second transport protocol are drawn from a set including Ethernet, Fibre Channel, and InfiniBand, Non-Volatile Memory Express (NVMe), and NVMe over Fabrics (NVMe-oF).

3 . A device according to claim 2 , wherein the first transport protocol and the second transport protocol are drawn from the set further including Remote Direct Memory Access (RDMA) over Converged Ethernet (ROCE) and iWarp.

4 . A device according to claim 1 , wherein the information written to the device further includes a protocol incompatibility between the device and host machine.

5 . A non-transitory memory for storing a data, comprising:

a data structure stored in said non-transitory memory, said data structure including:

a first storage for a transport protocol to be used by a device to communicate with a host machine, the transport protocol drawn from a set including Ethernet, Fibre Channel, InfiniBand, Non-Volatile Memory Express (NVMe), and NVMe over Fabrics (NVMe-oF);

a second storage for a first data written by the device, the first data specifying an identifier for the device; and

a third storage for data written by the device, the data specifying a reason why the device has a device incompatibility with the host machine,

wherein the device is installed in the host machine.

6 . A non-transitory memory according to claim 5 , wherein the data specifying a second reason why the device has a protocol incompatibility with host machine.

7 . A non-transitory memory according to claim 5 , wherein the data structure further includes a third storage for a transport sub-protocol to be used by the device, the transport sub-protocol drawn from a set including Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE) and iWarp.

8 . A non-transitory memory according to claim 5 , wherein the data structure further includes a third storage to store a firmware revision of the host machine.

9 . A non-transitory memory according to claim 5 , wherein the data structure further includes a third storage to store a firmware revision of the device.

10 . A method, comprising:

requesting a configuration of a host machine over a physical interface by a device, the device capable of using a first transport protocol or a second transport protocol to communicate with the host machine;

receiving at the device the configuration of the host machine over the physical interface;

identifying the first transport protocol to use responsive to the configuration;

configuring the device to lock the physical interface to the first transport protocol; and

writing information by the device,

wherein the device is installed in the host machine, and

wherein the information written to the device includes a device incompatibility between the device and the host machine.

11 . A method according to claim 10 , wherein the first transport protocol and the second transport protocol are drawn from a set including Ethernet, Fibre Channel, InfiniBand, Non-Volatile Memory Express (NVMe), and NVMe over Fabrics (NVMe-oF).

12 . A method according to claim 11 , wherein identifying a first transport protocol to use responsive to the data further includes identifying a transport sub-protocol to use responsive to the data, the transport sub-protocol drawn from a set further including Remote Direct Memory Access (RDMA) over Converged Ethernet (ROCE) and iWarp.

13 . A method according to claim 10 , wherein the information further includes at least one of a device identifier, a reason why the device has a protocol incompatibility with the host machine, and a firmware revision of the device.
