Abstract
A system includes a fabric switch including a motherboard, a baseboard management controller (BMC), a network switch configured to transport network signals, and a PCIe switch configured to transport PCIe signals; a midplane; and a plurality of device ports. Each of the plurality of device ports is configured to connect a storage device to the motherboard of the fabric switch over the midplane and carry the network signals and the PCIe signals over the midplane. The storage device is configurable in multiple modes based a protocol established over a fabric connection between the system and the storage device.
Claims19
A device comprising:
- a component configured to receive instructions using an interconnect signal;
- a multi-protocol connector configured to carry the interconnect signal, wherein the multi protocol connector comprises a pin configured to carry a storage protocol physical signal;
- and
- an Ethernet interface configured to transport an Ethernet physical signal using the pin of the multi-protocol connector;
- wherein the device is configured to use a first protocol using the interconnect signal in a first mode;
- and
- wherein the device is configured to use a second protocol using the Ethernet physical signal in a second mode, wherein the second protocol is for accessing nonvolatile memory.
A device comprising:
- a component configured to receive instructions using an interconnect signal;
- a multi-protocol connector configured to carry the interconnect signal, wherein the multi-protocol connector comprises a pin configured to carry a storage protocol physical signal;
- and
- an Ethernet interface configured to transport an Ethernet physical signal using the pin of the multi-protocol connector;
- wherein the device is configured to use a first protocol using the interconnect signal in a first mode;
- wherein the device is configurable in a second mode based on a second protocol, wherein the second protocol is for accessing nonvolatile memory.
A system comprising:
- a first device comprising a controller;
- and
- a second device comprising:
- a component configured to receive instructions from the first device using an interconnect signal;
- a multi-protocol connector configured to carry the interconnect signal, wherein the multi-protocol connector comprises a pin configured to carry a storage protocol physical signal;
- and
- an Ethernet interface configured to transport an Ethernet physical signal to the first device using the pin of the multi-protocol connector;
- wherein the second device is configured to use a first protocol using the interconnect signal in a first mode;
- and
- wherein the second device is configured to use a second protocol using the Ethernet physical signal in a second mode, wherein the second protocol is for accessing nonvolatile memory.
