Banana Pi BPI-R4 シングルボードコンピュータ
Banana Pi BPI-R4でOpenWrtを動かす
Banana Pi BPI-R4を専用ケースに入れてSoC(MT7988A)にヒートシンクを取り付けた
正面にはLEDインジケータとSDカードスロット、３つのSIMスロット、Resetボタンなど
2個のSFP+スロットとRJ-45（1000Base-T)のポートが4個備わっている
SFP+モジュールの冷却ファンとSoCチップのファンを分けて冷却性能を強化する
Banana Pi BPI-R4 は10GbpsのSFP+ポートを2個、1GbpsのRJ-45ポートを４個持つ、ルータやWi-Fi AP、NASなど動かすことを想定して作られた高性能なシングルボードコンピュータだ．この手のシングルボードコンピュータのCPUとしては、Intel x86系、Arm Coretex系、MIPS系のCPUコアがよく使われているが、今回のBanana Pi BPI-R4は Raspberry Piなどと同じく、ARM系のCPUコアが搭載されている．
Banana Pi BPI-R4の仕様や細かなデバイス構成は、Banana Pi BPI-R4 (BananaPi Docs) に詳しく掲載されているので、こちらのページを参照して欲しい．
Banana Pi-R4で使われているSoCチップ（MT7988A）の概要については、MediaTek社のホームページ “MediaTek Filogic 880” を参照すると良いだろう．このSoCチップは正に高性能ルータの心臓部として設計されたもので、このチップの特性を生かしたソフトウェアが開発されれば良いのだが、オープンソースベースのOpenWrtがこのチップの機能を採り入れたアプリケーションを開発することができれば良いのだが．．．
BPI-R4のSoCチップ（MT7988A）の発熱は、想像していたより低めで、OpenWrtを稼働させた状態でもチップの表面温度は50℃程度だった．重い負荷が掛かるとどの程度発熱が増加するのか不明だが、一応長時間の連続稼働を考慮して、簡単なヒートシンクと25mmφサイズのファン(5V仕様）で強制空冷することにした．
ヒートシンクのプラスチック製のピンの間隔は60mmだったので、PCパーツ用の小型ファン付きヒートシンクを流用することにした．ヒートシンクに付属のファンは40mmφタイプの10mmの高さの物だったが、少しノイジーだったので、25mmφサイズの静かなファンをサイドフローにして基板に両面テープで取り付けた．このファンは5V系の３ピン仕様のものなのだが、電源(+5V/Gnd）の２本と残りの１本（黄色）は回転数制御（検出？）のようだ．Banana PiのWikiページの写真には、5V FAN with PWM と記載があるので、実際にPWMで制御しているのかもしれないが、単に回転数を検出しているだけかもしれない．
SoCの発熱は予想よりも低かったのでヒートシンクだけでも問題なさそうだがが、SFP+モジュールの発熱の方がかなり心配だった．オプティカル系のSFP+モジュールであればモジュールの発熱はあまり気にしなくても良さそうだが、カッパー系の10GBase-Tモジュールを使用すると手で触れないくらい高温（火傷をするレベル）になってしまっていた．
SoCチップとSFP+スロットの両方を効率よく冷やすことの出来る空冷ファンを用意した方が良さそうだ．SFP+スロットの上にヒートシンクを貼って、ファンで強制空冷しないと熱暴走や発熱によるモジュールの障害が起きるだろう．Banana Pi-R4のファンコネクタの形状は一般的なPCマザーボードで使われている物とは異なり電圧も5Vなので、PCパーツとして出回っている12V系のファンはそのままでは使えないだろう．
このコネクタはJSTのPH-3ピンタイプ（ピンの間隔は2.0mm）なので、秋月電子や千石電子などのパーツショップやDigi-Keyなどで簡単に入手可能だが、自分で換装する必要がある．コネクタ嵌合用の工具（エンジニアのPA-20など）が必要なので、電子工作が趣味の人以外は難しいだろう．
5V系の小型ファンが見つからない場合は、基板上にはSATAデバイス用として5V/12Vが出力されている別な端子(JST XH-4ピンコネクタ）があるので、ここから12Vを取り出して汎用的な12V用のファンを回すという方法も使えるが、超静音タイプの小型の薄型ファンにして置いた方が良いだろう．12Vファンを5Vで動かすと低速で回転させることができるので静かなのだが、ファンによって5Vでは動作しない物も多いので実際に試して見ないと実用性があるかどうかは分からない．因みに、XH-4ピンコネクタのピンアサインは、#1: +12V, #2: GND, #3 : GND, #4: +5V （Boot切り替えスイッチ側）となっている．（https://wiki.banana-pi.org/File:BPI-R4-SATAPWR.jpg）
Amazonで、”40x40x10mm Raspberry Pi速度制御ファンDC 5V” という3線タイプのQIコネクタが付いた製品が売られていた．QIコネクタなのでそのままPH-3コネクタのピンに差し込むことができそうだが直ぐに外れてしまうだろう．やはりきちんとPH-3のハウジングに付け替えて置く必要がある. 5V系の小型ファンはRaspberry Pi用として売られている製品の中から探すのが無難かもしれない．
Banana Pi BPI-R4用に構成された Debian 11やUbuntu 22 Server などの汎用OSディストリビューションも幾つか出回っているようなので、小型の低消費電力サーバを構築するのにも向いている．但し、HDMIなどのディスプレイ出力は持ち合わせていないので、IoT系の小型ボードでは必須のシリアルコンソールによるOSのインストールなどをこなさなければならないので、初心者には少し敷居が高いかもしれない．
今回のBanana Pi BPI-R4 はNWルータとして用いるので、オープンソースベースでルータとしての実績やコミュニティーなどの充実度から、OpenWrtを選定し、最近の光ファイバー系のインターネットサービスでは標準的な機能となった、IPoE方式によるIPv4接続サービス（DS-LiteやMAP-E）に対応させることとする．
Banana Pi-R4では、オプションのWi-Fi7モジュール BPI-R4-NIC-BE14 を基盤の裏面に簡単に取り付けられるようになっているが、このモジュールを使うと日本国内では電波法の規定に違反する（技適の審査を受けていない）ので、Wi-Fiルータとしては使用することはできない．
現在自宅用のメイン回線としてNuro光を利用して、IPv4/IPv6デュアルスタックで運用を行っているが、Nuro光ではユーザに割り当てられていた半固定のグローバルIPv4アドレス（１個）が今後使えなくなってしまうことから、その代わりとして transix IPv4接続（固定IP）やJPIXなどの「v6プラス」固定IPサービスにも対応させ、Nuro光からこれらの固定IP接続サービスへ切り替える予定だ．
Banana Pi BPI-R4用のOpenWrtイメージをダウンロードする
OpenWrtは数多くのコンピュータに対応しているが、目的のコンピュータ用のOpenWrtディストリビューションを探し出すには、”Firmware Selector” というページにアクセスして、自分のコンピュータの名前やモデル名を入力すれば良い．BPI-R4は市場に出回るようになってからまだ日が浅いので、最新版（この記事を書いている時点では 23.0.5）で検索しても候補リストには出てこない．
BPI-R4用のディストリビューションイメージは、バージョンセレクターで”SNAPSHOT”版を選択すると候補として出てくるので、とりあえず今回はこのバージョンをインストールすることにする．
最新版を選択してもBPI-R4用のディストリビューションイメージは見つからない
“SNAPSHOT”版からBPI-R4用のディストリビューションイメージを探す
SD Card版用のイメージを選択しダウンロードする
今回は、OpenWrtのテスト用なので、一番簡単なSD Card版をダウンロードし、BPI-R4のBootstrap SW（起動セレクタスイッチ）を、SD Card起動（A,BともにSWを下側に倒す）にして、SD Cardから起動させてみる．
USB接続タイプのシリアルコンソールケーブル（3.3Vレベル入出力）をつないで、OpenWrt起動時のコンソールメッセージを拾ってみた．

ipコマンドの出力から、4つのRJ-45ポートが”eth0″、SFP+(WAN)が “eth2″、SFP+(LAN)が”eth1” となっていることが判る．また、これらの物理ポートは2つのブリッジポート “br-lan” と”br-wan” に紐付けられており、 “br-lan”側は、lan1(eth0)、lan2(eth0)、lan3(eth0)とSFP+(LAN) が、”br-wan” 側では wan(eth0)とSFP+(WAN)がポートメンバーとして構成されている．
“br-lan”側のIPは初期状態で、192.168.1.1/24 が割り当てられており、LAN側ではDHCPサーバ機能が働いているので接続したクライアントには、192.168.1.0/24 のセグメントのIPアドレスが払い出されている．
“br-wan” 側はDHCPクライアントとなっており、初期状態で NAPT(IPマスカレード）が動いており、LAN側のクライアントからNAPTされた状態でWAN側へ通信できる状態となっている．初期状態で何も設定していなくても、家庭用のホームルータとしての標準的な機能は働いているようだ．
OpenWrtにはWEB GUIコンソール機能が備わっている
上記のWEB GUIコンソール機能を司るLuCiパッケージは、”SNAPSHOT” 版には含まれていないので、下記の”opkg”コマンドを実行してLuCiパッケージをインストールする必要がある．

【追記】BananaPi-R4 用のOpenWRT 24.10.0(Stable版）がリリース
OpenWRT 24.10.0(Stable版）にBanana Pi-R4が登録されているのを確認できたので、FLET’S クロスなどの10Gbps系の接続サービスのルータとしてどの程度実用になるのか今後検証して行く予定だ．
とりあえず手持ちのSFP+モジュールがBanana Pi-R4上で問題なく使えるかどうか試してみることにしたが、最初に試した10GBase-TのSFP+モジュールが正常にリンクアップしなかったので、色々と原因を探ってみたが簡単には問題が解決しなかった．
手持ちの別な10GBase-TのSFP+モジュールでは問題なくリンクアップしたので、単純に最初にテストした10GBase-TのSFP+モジュールとBananaPi-R4との相性問題が生じているのかもしれない．このSFP+モジュールをPCIカードのNICで使用すると正常に使えるのでSFP+モジュールの障害という訳ではないようだ．
私は今まで様々なメーカーのNW機器を取り扱ってきたが、幸運なことにベンダロックインの経験は何度かあるが、SFPモジュールのガチャ問題（機器やモジュールの相性問題）には遭遇してこなかった．機器の調達や導入では大手のベンダーやインテグレータが介在しているので、ほぼメーカーの純正品か互換性が検証されている製品群しか扱ってこなかったということもあるが、今回初めてSFPモジュールのガチャ問題を引き当ててしまったようだ．
Open WRTの“Sinovoip BananaPi BPI-R4” のホームページに “Debugging SFP modules” という記載があって、Banana Pi-R4 では利用するSFP+モジュールによっては上手く稼働しない場合があるようだ．
とりあえず現時点で手持ちのSFP+モジュールで上手く稼働するかどうか確かめて見ることにする．
各種SFP+ モジュールの接続テスト
FS.COMの製品は格安でかつ割と高性能＆マニアックな（プロ受けしそうな）製品が揃っているので、最近は自宅用のNW機器をFS.COMの製品に置き換えているところだ．FS.COMのホームページを見ていると、かなり高性能な機器やパーツが何でこんな安価な値段で売られているのか不思議なくらいだ．日本で同じ性能のメジャーなメーカーの製品を購入すると少なくとも1桁は上の金額を出さなければ購入できないだろう．
先日、我が家のメインL2-SWとして使っていたCiscoの24ポート（SFPポートを含めると28ポート）スイッチ “WS-C2960L-24TS” を FS.COMの “S3900-24F4S-R”に置き換えたところだ．”S3900-24F4S-R”の使い勝手や概要については別な記事で紹介する予定だ．
FS.COMの製品は設計も製造も全て中国なので、サプライチェーンの問題やセキュリティー面で一抹の不安があるのでシビアな業務で使うのは少し不安があるが、自宅用として使っている分には問題となることは無さそうだ．政府系機関や関連団体などの調達ではHuweiやZTEなどのメーカーが締め出されているが、同じようにFS.COMの製品を採用するのは難しいだろう．
今回、検証する10GBase-T Copper RJ-45 SFP+ モジュールは手元にあった5個（種類としては3種類？）をBananaPi-R4のSFP+スロットに差し込んで実際に試してみた．購入した時期がバラバラなので、同じ製品型番であっても、中身は微妙に違っているようだ．FS.COMのSFPモジュールは色々と種類があって型番やパート番号だけでは区別が付きにくいので、発注する際は慎重に製品を選んだ方が良いだろう．
FS.COMの10GBase-T Copper RJ-45 SFP+ モジュールについては、 “https://www.fs.com/jp/products/178031.html?attribute=110486&id=4246947”から自分の環境に合った物を選択する必要がある．
FS.COMの10GBase-T Copper RJ-45 SFP+ モジュールには幾つか種類があって、NBase-T（マルチギガ/30m）タイプ、1G/10Gタイプ（30m/80m/100m）、産業用や低消費電力タイプなどに分かれている．更に、SFPモジュールのベンダロックイン回避対策として、各ベンダーのSFPモジュールの仕様（小細工）に合わせて互換性を考慮したモデルを選ぶ必要がある．最近は露骨なベンダロックイン機構を取り入れているメーカは少なくなってきたが、一部のメーカはまだ頑なに純正SFPモジュール以外は受け付けないようにしている．
今回テストしたFS.COM製のSFP+ Copper モジュール(RJ-45タイプ）
写真の10GのNICはオリオスペックで購入したノーブランドの格安NIC NB-INT-X520DAI-S (PCIe X8）で、チップはIntel 82599 を使用している．SFP+モジュールの上2つは “NETGEAR AXM765互換 10GBASE-T SFP+光モジュール(銅製 RJ-45 30m)” なのだが、別々に購入したものなので、中身は微妙に違っているようだ．一番上の物は、今回正常にリンクアップしなかったが、上から二番目のモジュールは何の問題もなくリンクアップした．
下の2つのSFP+モジュールはマルチギガタイプのもので、”Cisco SFP-10G-T-X互換 SFP+光モジュール(10M/100M/1G/2.5G/5G/10Gbps NBASE-T 銅製 RJ-45 30m)” なのだが、三番目のものが2024年5月に購入したもので、一番下が2025年4月に購入した物だ．同じ製品の筈だが、製品ラベルの貼り付け位置が表裏反対だったり、モジュールの形状も異なっていることからも、中身や仕様は微妙に異なるようだ．
上手くリンクアップできなかった原因を探るべく、OpenWRTのログ出力や “ethtool” やSFPモジュールのi2cダンプ情報などを取得してみることにする．
OpenWRTに下記のユーティリティーパッケージを追加する．これらのパッケージはデフォルトでは組み込まれていないので、自分でWEB GUI（Luci）かコマンドラインでインストールする必要がある．

2つのSFP+モジュールの違いは殆どないが、リンクアップ失敗する方は"i2cdetect -y 1" で検出されるi2cのデバイスアドレス '0x56' が無いことぐらいだろうか．eepromのダンプデータにも少し違いがあるが、これが何を意味しているのかは、メーカーの正式な仕様書でも見ない限り判らないだろう．この2つのモジュールの製造時期は恐らく "231212" "230301" なので、同じロットではないことは確かだ．単純なメーカーの製造ミスなのか、それともこのモジュールの単なる不具合（故障）なのか判断が付かない．同じメーカーの同じ製品で、当たり外れが有るとしたら困った物だ．．．
ちなみに、マルチギガタイプのモジュールに関しては問題なくリンクアップしているが、これらのモジュールも製造時期によって中身は結構違うようだ．マルチギガタイプのモジュールがBanana Pi-R4で使えない（1G/10Gだけ？）のではないかと危惧していたが、実際に使ってみると、Banana Pi-R4側は10Gと認識してしまっているようだが、対向側のL2-SW（Netgear MS510TXM）の2.5Gポートとの間で、きちんとリンクアップすることを確認している．但し、ethertoolの出力内容では、片方は "Auto-negotiation: on" 、もう一方は "Auto-negotiation: off" となっているので、本当にお互い2.5Gbpsで通じ合っているかどうか疑問なところだ．
10GBase-TタイプのSFP+モジュールはまだ発展途上の製品のようで、発熱や安定性の問題があるので可能であれば光ファイバ系のモジュールを使うことをお薦めする．家庭用の製品では2.5GタイプのRJ-45ポートを搭載したPCやネットワーク機器が増えてきているので、無理に10G化を計らなくても良いのではないだろうか．10Gを使いこなすにはかなりの出費を覚悟する必要がある．
NBase-T（所謂マルチギガ）は1Gと10Gのギャップを埋めるために後になって無理矢理作り出した妥協の産物的な規格なので、あまり積極的に使う気はしない．1G ⇒ 10G ⇒ 100G ⇒ 1TG と単純にスピードアップするのはやはり無理なので、2.5G, 5G, 25G, 40G, 400G という妥協（現実）路線に走ってしまったのだろう．
マルチギガタイプのモジュールでも問題なくリンクアップするようだ

同様なテストを光ファイバ系のSFP+モジュールでも行ってみたが、Banana Pi-R4とOpenWRTの組み合わせではきちんと認識していた．
テストした SFP+モジュールは、
・FS.COM SFP-10GLR-31 1310nm 10km タイプ (Netgear互換品）
・FS.COM SFP-10GSR-85 850nm 300m タイプ (Netgear互換品）
・Fortinet FN-TRN-SFP+LR (FTLX1475D3BCLFTN)
FS.COMの製品は自社で開発しているのか他社からのOEMなのかははっきりしないが、FortinetのモジュールはCoherent社のOEM FTLX1475D3BCL のようだ．
