FreeBSD 11.2RでConnectX-3 Pro ENで40GBASE-SR4環境を構築

試した環境

  • FreeBSD 11.2-RELEASE-p7
  • Mellanox ConnectX-3 Pro EN (MCX314A-BCCT)
  • Mellanox Firmware Tools (MFT) 4.11.0

手順

ドライバの読み込み

FreeBSD 10.4-RELEASEあたりから、ConnectX用のカーネルモジュールがGENERICに含まれるようになったため、mlx4enをkldloadするだけで使える。なお、以前のバージョンではmlx4とmlxenの2つに分かれていたっぽい。

mlx4enがConnectX-3以前用のモジュールで、mlx5enがConnectX-4以降用のモジュールとなる。大変に紛らわしい。

# kldload mlx4en
# echo 'mlx4en_load="YES"' >> /boot/loader.conf

正しく動いてればNICとしてmlxenが生えてくる。

$ ifconfig
mlxen0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
        options=ed07bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWFILTER,VLAN_HWTSO,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6>
        ether e4:1d:2d:xx:yy:e0
        hwaddr e4:1d:2d:xx:yy:e0
        inet 192.168.123.1 netmask 0xffffff00 broadcast 192.168.123.255
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect (40Gbase-CR4 <full-duplex,rxpause,txpause>)
        status: active

        options=ed07bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWFILTER,VLAN_HWTSO,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6>
        ether e4:1d:2d:xx:yy:e1
        hwaddr e4:1d:2d:xx:yy:e1
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect
        status: no carrier

ファームウェアの更新

Mellanox Firmware Tools (MFT)かmlxupを使ってカードのファームウェアの更新を行う。mlxupの方がコマンド一発で自動更新してくれて便利なんだけど、存在を知らずにMFTを使ってしまった…。MFTの方がいろいろユーティリティ付いてて良いんだもんね!(負け惜しみ

  1. MFTの動作にはpython2と/usr/bin/bashにbashが必要なので準備しておく。
  2. http://www.mellanox.com/page/management_toolsからFreeBSD用のMFTを落として展開。
    1. ちなみにmlxupはこっち→http://www.mellanox.com/page/mlxup_firmware_tool
  3. install.shを実行してインストール

FreeBSDの作法を無視して/usr/binに色々インストールしやがるけど気にしない。

無事インストールできれば、mst statusでカードの状態が表示される。

$ mst status
MST devices:
------------
  pci0:2:0:0    -       MT27520 Family [ConnectX-3 Pro]

カードの詳細情報を確認。-dの引数にはmst statusで得られたPCIバスを与える。

ファームウェアの更新。

ファームはhttp://www.mellanox.com/page/firmware_downloadから当該カードを選んで落としてくだしあ。

iperfしてみる

同じカードを搭載したWindowsクライアントとの間でiperfしてみる。サバクラの構成は下表のとおり。

サーバ クライアント
OS FreeBSD 11.2-RELEASE (x64) Windows 10 Pro. (x64)
M/B Supermicro X10DRi MSI X370 SLI PLUS
CPU Xeon E5-2648L v3 @1.8GHz ×2 Ryzen 7 1700 @3.0GHz
RAM Registered DDR4-2400 16GB×4 (2133MHz駆動) DDR4-2666 8GB×4
NIC接続 PCIe 3.0 x8 (CPU1側のx16に接続) PCIe 3.0 x8
PCIe 2.0 x4

iperf中の様子をタスクマネージャで見ると↓こんな感じ。瞬間風速20Gbpsがアツい。

PCIe 2.0×4接続

クライアント側NICをPCI Express 2.0 x4接続した時の結果。

バス帯域が片方向20Gbpsのためか、ジャンボフレームにしても11Gbps止まりとなった。

PCIe 3.0×8接続

クライアント側NICをPCI Express 3.0 x8接続した時の結果。

バス帯域は片方向64Gbpsとなり、十分な速度が出ている。とはいえ理論値の40Gbpsには及ばない。まだチューニングの余地はありそうだ。

iperf Done.

ジャンボフレームにすると流石の速度。スレッド数を増やすと速度も伸びるという情報があったが、自分の環境では4スレッドの時が最大で、単純に増やせば速くなるってものでもなかった。ここまで来ると、メモリ速度やその時その時のバス使用率など、マシンの足回りの影響が大きそう。
