Proxmox 8 服务器部署咨询：8块SAS数据盘+2块SSD系统盘的软硬RAID配置及虚拟机搭建

Hey there! No worries at all—homelabbing is all about learning as you go, and your hardware setup is actually really solid for what you want to do. Let’s break this down step by step to get your Proxmox VE server up and running smoothly.

一、RAID配置合理性确认与优化建议 #

1. 系统盘（2x1TB SATA SSD）RAID 1 #

Absolutely, RAID 1 is perfect for your OS drive! Mirroring the two SSDs ensures that if one fails, your system keeps running without downtime—critical for a server that hosts all your family’s services. Using your Lenovo 930-8i HW RAID card for this is totally fine; it’ll handle the mirroring efficiently, and Proxmox will recognize the RAID volume as a single disk during installation.

2. 数据盘（8x4TB SAS）RAID 6 #

RAID 6 is an excellent choice for 8 drives! It can tolerate up to 2 simultaneous disk failures, which is way more reliable than RAID 5 (only 1 failure tolerance) for a large drive set. Your 7200RPM SAS drives will balance capacity (24TB usable after RAID 6 overhead) and performance nicely for family data storage.

A quick alternative to consider if you want more flexibility later: you could set your RAID card to JBOD mode and use ZFS RAIDZ2 instead (which is software-defined but offers better data integrity features). But for a beginner, sticking with HW RAID 6 is totally safe and straightforward—you won’t have to mess with ZFS learning curves right away.

二、Proxmox VE基础部署步骤 #

• Prep your RAIDs first: Boot into your RAID card’s BIOS (usually by pressing Ctrl+R during startup, check Lenovo’s docs if that doesn’t work) and create your RAID 1 volume for the OS, then the RAID 6 volume for data. Wait for the initial sync to finish before moving on.
• Install Proxmox: Download the Proxmox VE 8 ISO, burn it to a USB drive, and boot your server from it. Follow the wizard to install onto your RAID 1 volume—set your server’s IP, root password, and hostname when prompted.
• Post-install setup: Log into the Proxmox web UI (https://[your-server-ip]:8006), open the Shell, and run these commands to update the system:

  apt update && apt dist-upgrade -y
  

  Reboot the server to apply all updates.
• Add data storage: Go to Datacenter -> Storage -> Add -> LVM (or Directory if you prefer) and select your RAID 6 volume. Name it something like family-data—this will be where you store VM/container disks, backups, and shared files.

三、对应业务场景的配置建议 #

1. 家庭私有云&数据共享 #

• Go with Nextcloud—it’s open-source, user-friendly, and perfect for family file sharing. Install it as an LXC container (lighter than a VM):
  • Click Create CT, pick a Debian/Ubuntu template, allocate 1-2 CPU cores, 2-4GB RAM, and assign disk space from your family-data storage.
  • Once the CT is running, follow Nextcloud’s official docs to install the server, create user accounts for your family, and set up file sync via their mobile/desktop apps.

2. Home Assistant智能家居 #

• The easiest way is to install Home Assistant as a VM:
  • Click Create VM, download the Home Assistant OS ISO directly from Proxmox’s ISO library, allocate 2 CPU cores, 4GB RAM (bump to 8GB if you have lots of smart devices), and 32GB disk space.
  • Boot the VM and follow the setup wizard to connect your smart devices—Home Assistant will auto-detect most popular brands.

3. Kids’ Voice Chat Server #

• Skip Discord/Teamspeak if you want a lightweight, self-hosted option—go with Mumble:
  • Create an Ubuntu LXC container, allocate 1 CPU core, 1GB RAM, and 10GB disk space.
  • Install the Mumble server via apt, set an admin password, and open port 64738 (UDP/TCP) on your router if you want friends outside your home to connect. It’s low-resource and super stable for kids’ chats.

4. Optional: Game Server #

• For games like Minecraft, install it in an LXC container or VM:
  • Minecraft: Use an Ubuntu CT, allocate 2-4 CPU cores, 4-8GB RAM, install Java, then download the Minecraft server JAR. Open port 25565 and share the server IP with your kid’s friends.
  • Adjust resources based on the game—most indie games will run fine on your Xeon Silver CPU and 1Gb network.

四、Quick Tips for New Homelabbers #

• Backup everything: Set up Proxmox backups to an external USB drive or another server—you don’t want to lose family photos or Home Assistant configs if something goes wrong.
• Enable monitoring: Turn on Proxmox’s Metric Server (Datacenter -> Metric Server) to keep an eye on CPU, RAM, and disk usage—you’ll catch issues before they become problems.
• Secure your server: Use strong passwords, enable Proxmox’s built-in firewall, and only forward ports you absolutely need on your router (e.g., for Home Assistant or the game server).
