Embodiment Construction

[0037] overview

[0038] Many modern servers are built within a 2U chassis cluster enclosure that includes four network hosts (eg, compute nodes). These servers, and similar implementations, can be very dense, requiring advanced thermal solutions that can be complex. Integrating another network interface card (NIC) into such a server enclosure is challenging, especially when dealing with high performance, high power NICs that generate more heat. Additionally, some NICs, especially high-performance, high-power NICs, are expensive to produce.

[0039] Each NIC in the server enclosure typically has a network connection to a top of rack (TOR) switch. As the number of compute nodes increases, so does the number of cables leading to the switch, complicating the installation and maintenance of network connections. Additionally, each NIC requires a corresponding port in the TOR switch.

[0040] Embodiments of the present invention alleviate these difficulties by providing a multi-...

Abstract

In one embodiment, an external multi-host system includes an external peripheral component bus (PCB) cable terminated with a first and second PCB connector plug, a first network host including a firstprocessor and a first PCB connector receptacle to receive the first PCB connector plug, and a second network host including a second processor and a multi-host network interface card, which includesa network connector receptacle to receive a first network connector plug terminating a network cable, a second PCB connector receptacle to provide connectivity with the first network host and to receive the second PCB connector plug, a first PCB edge-connector to provide connectivity with the second processor, and processing circuitry to operate communication with the first network host over the external PCB cable and with the second processor via the first PCB edge-connector, and exchange network packets between the network hosts and a network.

Description

technical field [0001] The present invention relates to computer network devices, and more particularly, but not limited to, multi-host network devices. Background technique [0002] Rack-mounted compute nodes can use standard Peripheral Component Interconnect Express (PCIe) connections to top of rack (TOR) switches to connect the rack to the rest of the network A network interface controller (Network Interface Controller, NIC) is used to communicate with the packet communication network. Since a compute node is an independent entity and is served as such, the compute node contains its own NIC and connects directly to the TOR switch. In some cases, a server shell may aggregate several computing nodes into a single unit, enabling sharing of certain resources among the nodes. Such resource sharing typically includes power, space, and thermal control functions. [0003] Peripheral Component Interconnect Express (PCIe) is a computer expansion bus standard used to connect a h...
