Network Interface Performance Considerations When Mounting External NAS Storage on Proxmox

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

✅ Network card performance directly affects the transfer speed and stability of external storage. This is one of the most critical factors when evaluating the use of external NAS storage with Proxmox VE. Below, I’ll break down the reasons, bottlenecks, recommended architecture, and hardware selection for you in detail. 🧭 1. Why Does NIC Performance…

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…

於 Proxmox 上使用Synology NAS

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

這是實務上 Proxmox VE (PVE) 常見的應用場景之一──把現有的 Synology NAS (群暉) 掛載到 PVE 當作 儲存池 (Storage Pool),讓 PVE VM / CT / ISO / Backup 都可以直接使用 NAS 空間。 🧭 一、整體架構說明 Proxmox 支援多種遠端儲存協定: 類型 群暉支援 適用用途 備註 NFS (Network File System) ✅ 最常見,適合 VM 映像檔、備份、ISO 速度穩定、設定簡單 SMB/CIFS (Windows 共享) ✅ 適合 ISO、備份 不建議放 VM Disk iSCSI ✅ 適合高效能 VM…

PBS Backup Architecture vs Traditional “Full / Incremental / Differential Backup”

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

Q: In PBS, I see many backup entries — which one is a full backup and which one is incremental? This is one of the most common questions people have when they first start using Proxmox Backup Server (PBS): Why are there so many backups, and why does each one look like a “full backup”?Which…

PBS 備份架構 vs 傳統「全備 / 增備 / 差異備份」

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

Q:在PBS 上,看到很多備份的資料,到底那一份是完全備份?那一份是增量備份? 這個問題正是很多人在剛接觸 Proxmox Backup Server (PBS) 時的疑惑之一: 為什麼備份那麼多份,但每一份看起來都像「完整備份」?到底哪一份是全備?哪一份是增量? 其實這是因為 PBS 的架構與傳統「全備 / 增備 / 差異備份」完全不同。我們來逐層拆解讓你清楚理解👇 🧩 一、PBS 的備份方式:不是傳統的「全備 + 增備」,而是 去重複快照備份 (deduplicated snapshot) 每一份你在 GUI 上看到的備份(例如 ct/104/2025-10-23T06:02:57Z)在邏輯上都是一份 完整可還原的快照(snapshot)。但在物理上,它只會儲存「與前一版本不同的資料塊(chunks)」。 👉 換句話說: 🔬 二、內部原理:Chunk-based Deduplication PBS 備份時,會將 VM/LXC 的磁碟內容切成很多「chunk」(預設 4 MB 一個),並且對每個 chunk 計算 SHA-256 雜湊值。 流程如下: 所以,雖然你看到有 10 多個時間點: 但實際上: 📦 三、檔案結構舉例 在 PBS 的…
