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)…

Evaluating Proxmox Support for High-End Network Cards

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

This is indeed one of the most common concerns for enterprises transitioning from VMware to Proxmox VE (PVE).That concern is reasonable — but in fact, Proxmox’s hardware compatibility is excellent, especially for high-end NICs. As long as you choose wisely, most cards are truly plug-and-play. Here’s a complete breakdown: 🧠 1. Core Foundation of Proxmox:…

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…

於 Proxmox 上掛載外部 NAS 儲存時網卡效能的考量

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

✅ 網卡效能直接影響外部儲存的傳輸速率與穩定性。 這是評估 Proxmox 掛載外部 NAS 儲存時最關鍵的問題之一。 下面我分幾個層面幫你完整說明 原因、瓶頸、建議架構與選型考量。 🧭 一、為什麼網卡效能會影響 NAS 存取速度? 當 PVE 使用 NFS / iSCSI / SMB 掛載外部 NAS 時,所有虛擬機或容器的磁碟 I/O(讀寫)都要經過 網路傳輸。 換句話說:「VM 的磁碟 I/O = 網路封包」所以,網路頻寬與延遲 = 磁碟效能的上限與穩定性 ⚙️ 二、實際瓶頸分析 網路介面 理論頻寬 實際可用效能(扣除協定開銷) 約當磁碟速度 1GbE 125 MB/s 100–110 MB/s 約等於 SATA SSD 單碟效能上限 2.5GbE 312 MB/s 270–290 MB/s 略優於 SATA…
