Understanding VLAN Configuration in Proxmox VE — A Practical Guide

Posted on 2025-11-042025-11-04 by Rico

Introduction In a virtualized environment, VLANs (Virtual LANs) play a crucial role in network isolation and segmentation.Within Proxmox VE (PVE), VLANs can be managed through Linux bridges (e.g., vmbr0) combined with VLAN tagging, allowing multiple VMs to share a single physical NIC while staying securely separated across different subnets.This article summarizes my hands-on experience configuring…

Proxmox VE 中的 VLAN 架構與 VM 網路設定實戰指南

Posted on 2025-11-042025-11-04 by Rico

前言 在虛擬化環境中,VLAN(Virtual LAN) 是網路隔離與分流的核心機制。在 Proxmox VE (PVE) 裡,透過 Linux Bridge(例如 vmbr0)搭配 VLAN tag,就能讓多個 VM 共用一張實體網卡,卻依然區隔不同子網。這篇文章記錄了我在實際部署過程中對 VLAN 架構的理解與設定步驟,作為日後參考筆記。 一、VLAN 的基本概念 在實體交換器(例如 Unifi、Juniper、Cisco)上,只要對 port 設為 Trunk 模式,允許多個 VLAN 通過,就能讓 Proxmox 的一張 NIC(例如 enp3s0)同時承載多個 VLAN。 二、Proxmox 中的網路邏輯 Proxmox 的網路基礎是 Linux Bridge。當你建立 vmbr0 時,它就像一個虛擬交換器,VM、Container 與實體網卡都能接在上面。 範例: 🔹 說明: 三、在 VM 上設定 VLAN Tag 每台 VM 的網卡(例如 net0)都可以指定 VLAN tag。當…

Understanding Software-Defined Storage and Ceph – A Modern Approach to Data Management

Posted on 2025-11-042025-11-04 by Rico

Introduction In modern IT infrastructure, data is the lifeblood of every business. As virtualization, containers, and cloud systems grow, traditional storage solutions often struggle to keep up. Software-Defined Storage (SDS) has emerged as a transformative approach — shifting intelligence from proprietary hardware to flexible, scalable software. One of the most powerful open-source implementations of SDS…

VMware’s Licensing Overhaul: What Should Enterprises Do Next?

Posted on 2025-11-042025-11-04 by Rico

Evaluating the Cost Efficiency of Proxmox as an Alternative Virtualization Platform In recent years, VMware’s acquisition by Broadcom has led to major changes in its product licensing strategy.The company has transitioned entirely from perpetual licenses to a subscription-based model, now billed per CPU core.For enterprises still running older versions such as vSphere 5.x–6.x, these changes…

VMware 授權大變動,企業該如何因應?

Posted on 2025-11-042025-11-04 by Rico

Proxmox 成本效益與實務導入評估 近年來,隨著 VMware 被 Broadcom 併購後,產品授權策略出現重大改變。從原本的一次性永久授權(Perpetual License),全面轉向 訂閱制(Subscription Model),並採用 「每核心計費(Per-core Licensing)」 的新規定,這對中大型企業 IT 架構造成了不小的衝擊。 許多企業目前仍在使用舊版 vSphere 5.x ~ 6.x 系列。由於這些版本已不再獲得安全更新,面臨升級時,授權費用的急遽上升成為決策關鍵。本文將以實際企業環境為例,分析「升級 VMware vs. 導入 Proxmox」的成本與功能差異。 一、現況設定:企業現有虛擬化環境 項目 數量 實體伺服器 25 台 每台 CPU 插槽數 2 每 CPU 核心數 10 cores 總插槽數 50 sockets 實際核心數 500 cores 二、VMware 新制授權計價方式 自 2024 年起,VMware(現 Broadcom)全面導入新的 vSphere Foundation (VVF)…

Proxmox 對高階網卡的支援度評估

Posted on 2025-11-032025-11-03 by Rico

這點確實是很多企業在從 VMware 過渡到 Proxmox VE (PVE) 時最關心的議題之一。這樣的擔心是合理的──但 Proxmox 在硬體支援度方面其實非常強,尤其是高階網卡,只要選擇得當,大部分都能「即插即用」。以下我幫你完整解析: 🧠 一、Proxmox 的核心基礎:Debian + Linux Kernel Proxmox 是基於 Debian (目前 PVE 8 使用 Debian 12 Bookworm)並採用 Linux Kernel 6.x 系列(常見為 6.8 或 6.5)。 ✅ 這代表:只要 Linux 支援的網卡,Proxmox 幾乎都能直接使用。也就是說,驅動層級支援 ≈ Debian / Ubuntu Server 支援程度。 ⚙️ 二、Proxmox 對高階網卡的支援現況(2025 年最新狀況) ✅ 穩定支援、企業常用品牌: 廠牌 系列 狀態 備註 Intel i210…
