ESXi 8.0 Free環境で、NVMe SSDの温度が取得できるのかを確認してみた
まず情報源は「Commands to Display S.M.A.R.T. Data for NVMe Devices in ESXi」
S.M.A.R.T.データの読み出しを行うコマンドがある、と
NVMe系コマンド操作で情報取得する場合
まず、NVMeストレージの一覧を確認
[root@esxi:~] esxcli nvme device list
HBA Name Status Signature

この環境には２つのNVMe SSDがあるので、２個表示される
１個目を確認

Composite Temperatureの値はあるが、Temperature Sensorの値が全部なし
これは、怪しいメーカ製のNVMe SSD(TWSC TSC1BN2562DF7T10A)であることに由来していると思われる
じゃあ、２個目(SPD SP7002D2TNGH)は？

検証
ここまではNVMe SSDのヒートシンクに向けて冷却ファンが稼働している状態で実行していた
冷却ファンを止めて温度上昇が発生するのかを検証
