運算節點（HCI）安裝指南

運算節點（HCI）概覽

運算節點（HCI）透過堆疊CPU與RAM，為CubeCOS超融合基礎架構提供運算資源與記憶體。
配備額外 SSD 與 HDD 硬碟的運算節點將被整合至儲存池中，作為運算儲存節點使用。

資訊

在開始安裝運算節點（HCI）之前，您需要先準備一個管理融合節點或控制節點。請務必仔細閱讀這些要求，因為成功部署運算節點（超融合基礎架構）的安裝取決於此。

需求

變更節點密碼

若要將節點加入現有的 CubeCOS 叢集，該節點的 root 密碼必須與目標叢集的 root 密碼相符。

Prerequisite

在加入新節點之前，必須先變更目標叢集的叢集密碼。若您尚未執行此操作，請參閱有關變更叢集密碼的文件。

將節點密碼變更為與目標叢集密碼一致

在節點設定過程中，系統會提示您變更節點密碼。請依照螢幕上的指示，將密碼更新為與目標叢集的 root 密碼相符。

請輸入舊密碼。
1. 預設密碼是 admin
請輸入新密碼，該密碼必須與目標叢集的 root 密碼相符。
請確認新密碼。
請確認密碼變更的成功訊息為「密碼已成功變更。」

[選擇性] 建立網路介面聚合

網路綁定屬可選功能，僅適用於需要網路冗餘的部署情境。欲深入瞭解網路配置選項與部署情境，請參閱網路配置章節。

如果不需要設定網路介面聚合，可直接前往 Configure IP address - IF.1 。

資訊

若已連接網路纜線，[速度]欄位將顯示連線狀態（例如：1000Mb/s、10Gb/s）。若未偵測到連接線，則顯示 N/A。

警告

請勿使用 bond0、bond1、bondx 或 bd0 作為綁定介面名稱。這些名稱已被保留或可能與系統預設值衝突。
