Description

The utility model relates to the field of electronics, namely to the field of compact devices as part of hardware computing networks, and intended for use as part of trusted hardware computing platforms of critical information infrastructure in industry and telecommunications.

A useful model "Interface board" is known (patent CN206686448U, priority 05/09/2017), designed to solve the problem of saving material resources by choosing one of two external Ethernet interfaces (RJ-45) or USB2.0 on the "interface board". The utility model provides the user with the opportunity to choose which connector to mount on a particular board, depending on the task being solved using the network, namely: a connector for a USB 2.0 or Ethernet (RJ-45) interface. Thus, there is a savings due to the fact that there is no need to route 2 boards: one for the USB 2.0 interface, and the other for the RJ-45 interface.

The disadvantage of this solution is that the device according to patent CN206686448U does not allow using the same connector for different interfaces.

The closest technical solution to the claimed one is the utility model "Network server with a modular switching device" (patent CN203689292U, priority 01/28/2014). This solution proposes a modular system consisting of a carrier board on which the main computing components, memory, and power are located. It is supposed to install various peripheral modules on the carrier board, on which network adapters and connectors are located. Modules can contain a different number of network adapters, ports, and a different set of network connectors. Peripheral modules are united by a single construct (overall dimensions, mounting dimensions), as well as the location and type of connector for communication with the carrier board.

The advantage of this solution is the ability to organize a different number of Ethernet ports and different types of Ethernet connectors using a set of modules and one carrier board. At the same time, it is not required to develop its own carrier board for each configuration option or to make a set of carrier boards for each configuration option.

The disadvantage of the device according to patent No. CN203689292U is the need to develop a set of modules with a different set of Ethernet ports. In addition, each module is responsible only for a specific configuration, and there can be a lot of them. For example, if we have an arbitrary configuration of 5 Ethernet ports using two types of connectors, then the number of combinations will be 2 to the power of 5, that is, 32 configurations. So, to use this solution, it is necessary to develop and manufacture 32 types of modules. With an increase in the number of ports, the range of modules increases exponentially.

To connect to Ethernet (1GbE) fiber-optic communication lines, it is required to use an SFP connector instead of an RJ-45 connector, and the need for the number of connectors of one type or another may vary depending on the task, which may not be provided by every device. For example, the Lanner NCA-1011 Compact Desktop Network Appliance (https://www.lannerinc.com/products/network-appliances/x86-desktop-network-appliances/nca-1011) on the market has 5 RJ-45 connectors, but there is no SFP connector, which makes it impossible to use this device in tasks that require connection to one or more fiber optic lines.

There are network devices with port configuration: 1 or 2 SFP and 4 RJ-45, for example ELTEX ESR-10 (https://eltexcm.ru/catalog/servisnye-marshrutizatory/esr-10-servisniy-marshrutizator.html).

Thus, well-known devices of the same purpose contain a fixed number of ports designed for specific types of connection of external devices. This limits the possibility of using these devices as part of information networks and increases the cost of creating the information infrastructure of industrial enterprises.

The problem to be solved is to create a network computing device with an Intel 80×86 architecture CPU with a computing performance of at least 11 GFLOPS. The device must provide the ability to configure the network hardware platform in terms of RJ-45 and SFP connectors without replacing the electronic board (motherboard) and without using a large set of expansion modules.

The technical result of the claimed utility model is that the claimed compact network computing device provides an extended set of interfaces and functionality while reducing the cost of creating hardware networks and optimizing investment risks during their implementation.

A network computing device consists of a case, a printed circuit board with components (motherboard), RAM modules, an information storage device (drive), and a power source. The device is equipped with a 4-core processor with Intel architecture 80×86 with a computing performance of at least 11 GFLOPS.

The printed circuit board is equipped with a seat that allows using both an RJ-45 connector and an SFP connector as an Ethernet port through the use of a universal seat, which is a circuit and topological solution that combines the network adapter necessary for using RJ-45 and SFP connectors, a combined footprint for RJ-45 and SFP connectors, as well as a flexibly configurable network of connections between the network adapter and connectors.

Interface connectors are located on the front side of the case LAN (RJ-45 and/or SFP), USB 3.0, USB 2.0, console port, HDMI, power button, reset button. The power connector is located on the opposite side of the case relative to the front.

At least one hole is provided on the case for attaching at least one Wi-Fi or GSM antenna. The case allows you to implement both active (fan) and passive (no moving parts) cooling through the vents. Additional vents in the case to provide convection, as well as heatsinks, are allowed. The case is fixed to flat surfaces using threaded elements and holes, with which the case can be installed on a table or in a 19” standard rack. At the same time, the case and the front panels of the case are made of aluminum or other metal by laser cutting, which ensures the cost-effectiveness of manufacturing a case with a given configuration of Ethernet ports.

The claimed network computing device has a printed circuit board (motherboard) containing: 4-core integrated Intel® Atom™ central processor, connectors for connecting RAM modules (DDR), connectors for connecting drives (SSD, HDD), USB connectors, HDMI connector, power connectors. The printed circuit board of the network computing device has a universal seat for RJ-45 and SFP connectors for connecting with external network devices.

The circuitry and design solution of the RJ-45/SFP universal seat allows using both the RJ-45 connector and the SFP connector on the printed circuit board as an Ethernet port, which makes it possible to flexibly configure the ports of the network computing device depending on the task using the same the same printed circuit board without changing its topology. The solution is presented in the form of a diagram using special contact-compatible Ethernet controllers, one of which is designed to work with an RJ-45 connector, and the other for working with SFP, while connecting the controllers to RJ-45 or SFP connectors using a flexibly configurable a circuit implemented on a printed circuit board that allows, by mounting part of the passive components (resistors, capacitors, inductances), to be connected both to one type of connector and to another. To connect to the SFP connector, one type of controller and the part of the components related to it are mounted; to connect to the RJ-45 connector, the second type of controller and the part of the components related to it are mounted.

The device can be equipped with a pull-proof power connector.

The device allows you to implement high-performance solutions that can be used for specific tasks, or expand the functionality of a network computing device for a specific individual task. The claimed device is suitable for use in confined spaces due to its compact form factor and the possibility of using a passive cooling system, as well as due to the constructive ability to flexibly configure the network hardware platform in terms of connecting external devices via RJ-45 and SFP ports.
