A survey of SBCs and Network devices




Single-Board Computer(SBC) 調査の概要

最近、Single-Board Comupter が AmazonAliExpress などで、格安なものや多種多様なものが増えてきたので、簡単に調査をしました。今までは、Raspberry Pi や NVIDIA Jetson が主流だったが、入手困難や高騰しているので、様々な選択肢が増えてきました。今回は、私が購入を検討したものを紹介します。

Single-Board Computer (SBC) とは

Single-Board Computer(SBC) は、電子基板に Central Processing Unit(CPU) やMicroprocessor、Memory、Storage、Chipset、Input/Output Interface、Expansion Slots などの最小限の Component で実装さてたコンピュータです。Linux や Windows などの Operating System (OS) が動作しており、様々な用途で利用できる比較的小さなコンピュータです。SBC とは別に、 高度な処理を行える Microprocessor ではなく、Micro-Control Unit(MCU) や System on System on Chip(SoC) などのプロセッサで組み込み制御などに用いる Arduino などの基盤は、Single-board microcontroller と呼びます。

SBC などを購入するにあたり考慮したいこと

購入するにあたり、想像しててものと違うなどを起こさないために、公式サイトなどの Document を調べましょう。また、レビュー記事も製品によってありますので、確認すると良いと思います。


様々なチップを使って作られているのでスペックや Chipset を確認しましょう。Instruction Set Architecture(ISA)でも、コンパイラの最適化の適応度合いでも、プログラムの性能が変わることがあります。また、Early bird releaseでもスペックが違う時もあります。そして、インターフェイスと接続方式でも性能は変わります。


安価なものが多く品質に問題があることがあります。コスト削減などにより、Dual-in-line package(DIP、リード部品) をリロー方式や手付けではなくリフロー方式のみで接合して、足を半田で固定しない基盤もある可能性があります。基盤の半田付けの方法はこちらを参考にしてください。


Raspberry Pi や Jetson Nano は、代表的なものなので、公式サイトや Switch Science や AKIZUKI DENSHI TSUSHO などで入手できる時があります。しかし、売り切れになっていたり、特定のスペックしか買えないことがあります。何かの予算で買う際には、正規な代理店を選びますが、個人的に購入する際には、Aliexpress や個人輸入の方が安い場合もあります。また、Raspberry Piは、ケースや拡張モジュールが豊富であります。したがって、Raspberry Piの大きさに合わせる製品もあります。このような製品は、どこかにPiなど入っていることが多いですが、大きさや固定の為の穴位置などは、確認した方が良いです。

Raspberry Pi 4B

Raspberry Pi 4Bは、ARM の CPU が搭載しており、RAM のスペックとして1GBと2GB、4GB、8GBがあります。
Raspberry Pi Imager から Raspberry Pi OS をインストールできて、簡単に動かすことができます。Cortex-A72は、優秀な印象です。最近は、高騰してたり、良い性能の SBC があるので悩みどころです。Raspberry Piは、SONYが作っているので応援したいです。また、Raspberry Pi 5のもありますので、このタイミングで購入するのは考え所ですね。

Co-Packaged Optics (CPO) / Software Defined SFP / Smart SFP

SFP や QSFP などの Transceiver に、ASIC や CPU を搭載することにより、高帯域や低消費電力、コスト削減、Switch の処理を OFFROAD、機能追加などを行えます。

Co-Packaged Optics (CPO)

As the demand for network and compute fabric bandwidth continues to accelerate, innovation in both system and chip architectures are required to mitigate the slowing of Moore's law. At the same time, copper interconnects are fast reaching their bandwidth-distance limits. Silicon photonics is critical to sustaining rapid data growth and supporting high-bandwidth applications, such as Ethernet switching, artificial intelligence / machine learning (AI/ML) and high-performance computing (HPC).
Co-Packaged Optics (CPO) is an advanced heterogeneous integration of optics and silicon on a single packaged substrate aimed at addressing next generation bandwidth and power challenges. CPO brings together a wide range of expertise in fiber optics, digital signal processing (DSP), switch ASICs, and state-of-the-art packaging & test to provide disruptive system value for the data center and cloud infrastructure.Co-Packaged Optics (CPO)

PlumSpace Software Defined Smart SFP

Smart SFP also features the Intel Data Plane Development Kit (DPDK) which greatly boosts packet processing performance and throughput to improve data plane performance.
Smart SFP designed for low-cost and high-volume market. It’s is easily pluggable into SFP ports of switches and routers. It delivers substantial OpEx savings by eliminating additional power, space and cabling expenses.Software Defined Smart SFP


Experience the power of simplicity of next-generation transceivers
Smart SFPs bring simplicity to your network by design. Integrating network functions to transceivers, Smart SFPs can replace several devices in your network. You decrease the overall number of devices used in your network, thereby making your network much simpler. With a simple network, you can lower overall power consumptions as well as carbon footprint and reduce your OPEX. Smart SFPs are zero footprint solution and CAPEX gets lower for the same level of network enhancement by simply replacing existing transceivers.
Integrating packet processors in transceivers, Smart SFPs are next-genearation transceivers which will introduce intelligence to your network in the most cost-effective way. In conformance with MSA, they operate in the entire Industrial Temperature range. By simply replacing existing transceivers with Smart SFPs, you can provide better service to your customer. Smart SFPs are jointly developed by OE Solutions and AimValley.ABOUT SMART SFP

Chelsio Terminator 7 ASIC

In addition to the above offloads, versions of T7 integrate 8 A72 Arm cores that are exposed to the user. These Arm cores offload the traffic to the integrated 400Gb DPU on the chip and as a result the Arm cores are available to support the user’s specific application. The T7 transport engine is a programmable DPU that can offload protocol processing per connection, per-server, per-interface, while simultaneously providing complete stateless offload to traffic for non-offloaded connections (processed by operating systems stack running on host CPU). The T7 also provides a flexible direct data placement capability for regular TCP sockets, with all the benefits of zero-copy and kernel bypass without rewriting the applications. To support the Arm Cores, Chelsio provides a full development and debug software package to allow development of application specific firmware.Terminator 7 ASIC
