    Ginz got a reaction from Bianks84 in Getting stuck setting up mass storage NAS   
    If you're interested in the topic, and enjoy this kind of thing as a hobby, then I would definitely recommend learning how to use Linux.
    It may seem scary/complicated at first, but having a project like this will help you get familiar with the operating system, as well as using containers.
    Getting some experience in Linux will vastly increase the amount of homelabbing projects that you can take on, and will also give you a lot of experience should you wish to pursue this kind of stuff as a career.
     
    If this sounds like the kind of thing you would like to try out, then I would:
    Look into a hypervisor such as Proxmox (which uses KVM underneath) Storage can be set up in a few different ways: You could have your hypervisor control all of your disks, and then create virtual disks for your VM. (I'd recommend this approach for a beginner) You could dedicate a ssd/hdd for the hypervisor (or even a usb if using esxi), then passthrough a secondary disk(s) to a virtual machine. You could have your hypervisor control all of your disks, create a virtual disk for your VM's OS, and then use NFS to grant your VM access to your hypervisor's disk. Create a VM and install Debian/Ubuntu/CentOS on it. Note that setting up a static IP for your server, or dhcp reservation will be key to making sure that the VM is accessible even after rebooting your modem/router. Learn how to remotely access this VM via ssh. Watch an introductory video on Docker, and then go through a few tutorials to get yourself familiar with it. Read a tutorial on creating a Nextcloud instance via docker (try use docker-compose as you can easily see what container configuration that you have defined) Try accessing your Nextcloud instance over local lan. Don't expose Nextcloud to the internet unless using https.  
    Some considerations and more advanced topics
    Learn about ssh keys, and set them up to increase security around remotely accessing your server. Learn about dns, and consider getting a domain (there are some cheap/free options) Learn about https, certificates and reverse proxies before exposing Nextcloud to the internet. Traefik, caddy, nginx, and haproxy are all examples of reverse proxies. Letsencrypt is a service which you can use to issue https certificates to your sites (requires a domain) Some other cool things you can deploy via docker: pihole bookstack emby/plex wordpress

    I would suggest using ECC ram with a ZFS filesystem (I am using ZFS on Linux atm) with raidz or raidz2 (note that for raidz, I would recommend using 5 drives, and 6 drives for raidz2).
    You can run a hypervisor such as Proxmox and then virtualise your different servers in separate VMs or containers.

    Receiving fist parts & Installing SSD's in the drivebays.
     
     
    So far I have received the flowing parts:

    These two USB flash drives will be used to install ESXi On.
    The SSD's will be for the VM datastores.
     


    I also received 3 out of 33 hard-drives, in total the system will have 37 4TB drives though as I will reuse 4 from my old server.
    I will end up making 2 arrays:
    RAID-60 array with 32x4TB and a RAID-5 array with 4x4TB which leaves one 4TB as a global hot spare.
     


    These SSD's will be used to for running the VM's on the storage node, the VM node will have 1TB SSD's.
    The SSD's will be running in RAID-1 for redundancy



    The stock Supermicro drive bays don't support 2.5" drives.
    I had to buy 4 of these drive bays to mount the SSD's in my server.



    Time to install the SSD's in the drive bays.



    They are simply installed with 4 screws on the side of the SSD's.


    Here are some more pics I took:

    Edit: There's enough info here for this post to start being useful, but it's still not anywhere close to done. Any chance this can get stickied? 
     
    @wpirobotbuilder @looney @alpenwasser here it is!   Thought you guys would be interested in this.
     
    If you notice any errors in my information or find important information that is missing or have any questions, please ask! I will be maintaining this thread for as long as I am a forum member.
     
    1 What is the purpose of this tutorial?

    This tutorial attempts to thoroughly cover the basics of ZFS: What it is, why you would want to use it, how to set it up, and how to use it.
     
    This tutorial is meant to be understandable by someone with no prior knowledge of ZFS, although a basic knowledge of *nix operating systems is expected for installation section.

     
    2 What is ZFS?
     
    3 Why should I use ZFS?
     
    3.2 Cost

    Cost is always a limiting factor. Hardware RAID requires expensive controllers, some software RAID solutions require you pay for the software (flexRAID), and most solutions encourage the use of enterprise (read: SAS) class disks because of their higher speeds and lower read/write error rates.
     
    ZFS, by contrast, is free, encourages the use of cheep disks (read: SATA), and solves the issues of read/write errors in software instead of hardware, making it incredibly cheep. The only potential for extra cost in ZFS implementation arises from ZFS's desire for lots of ram and a fast cache drive (usually an SSD). See sample configurations in section 10 for a better look at cost analysis.

     
    3.3 Speed

    "So if ZFS is redundant AND cheep, it can't be fast, can it? There's no way you can have all three," you must be thinking.
     
    Well I'm here to tell you that you thought wrong! Implemented properly, ZFS can be faster than just about all forms of hardware and software RAID.
     
    ZFS achieves its speed through caching, logging, deduplication, and compression. 
     
    3.3.1 Caching & Logging
    By default, ZFS will use up to 7/8 if your system memory as a kind of level 1 cache and can be configured to use a fast disk (read: an SSD) as a kind of level 2 cache. In ZFS terms the memory-based cache is know at the ARC, or adaptive replacement cache, and the fast disk based cache is known as the L2 ARC, or level 2 ARC. ZFS also has an optional ZIL, or ZFS Intent Log, a dedicated partition of a fast disk that ZFS uses to store transactions temporarily before they are read or written to the disk in bursts.
     
    3.3.2 Deduplication & Compression
    ZFS natively supports both deduplication and compression. Deduplication, for those who don't know, allows for copies or near copies of data to be stored as a reference to the original data instead of as a straight copy, which saves space at the cost of a bit of CPU time and a lot of memory. Deuplication and compression can be enabled for an entire ZFS pool, or just a few datasets. I'll get into datasets later, but for now just think of them as folders.


     
    4: Why shouldn't I use ZFS?

    There are a few important caveats that one should be aware of before use:
     
    4.1 License Incompatibility
     
    4.2 ZOL is Incomplete
     
    4.3 No Defragmentation
     
    4.4 Hardware

     
    5 What do I need to use ZFS?

    I alluded to this topic a bit in the last section, but here I will explicitly define ZFSs requirements.
     
    5.1 Operating System
    5.2 Drives
    5.3 Memory
    5.4 Other Considerations

    5.4.1 Motherboard

    For a low end ZFS server, any cheep consumer motherboard will do, however for mid-range or high end builds, server motherboard should be used for their ECC memory and buffered DIMM support. See section 10 for more info.

    5.4.2 CPU

    ZFS is generally not too computationally intensive, but if you want to use some of its advanced features (compression, deduplication, L2ARC, etc) it will need more horsepower to ensure ideal performance. Low end and lower mid range systems will work well on an Intel Pentium or i3 or AMD APU. Upper-mid-range systems will need quad core chips such as a 4C Xeon E3, 4C Xeon E5 (E5 series supports buffered dimms (needed for >32GB of memory)), or 4C Opterons. High-end systems will need one or more higher-core count Xeon E5s or Opterons.

    10 Sample Setups

    Please note that these are only sample setups. If you notice hardware/brand bias in these builds, it's not because I don't like brand X or that I think brand Y performs better than brand Z, it's just because these are brands that I happen to use. These are just sample builds.
     
    To be perfectly clear, THESE ARE JUST EXAMPLES. I don't want anyone in the comments telling me "If you swap x for y in the build it will be $10 cheeper." That's not the point of this. These are just ballparks.
     
    Also note that if anyone has specific system requirements/brand preferences, tell me what you're looking for in the comments and I will gladly throw together some system specs for you. (eg: "I want a 16TB box and I prefer seagate, AMD, and kingston. I also want it to be fast to I can run VMs on it.").
     
    Also, if you have specific questions like "how should I partition my SSD for mamimum performance?" please ask.

Use 100GB of the M500 for boot, 20GB for swap, 60GB for the L2ARC and 1GB for the ZIL. Leave the rest of the drive empty so that it will still get high IOPS when the L2ARC is full.
     
    Note: I went with an M500 specifically because it has power loss data protection (aka capacitor banks to flush cache), which I felt was important for a server. It's also very cheep given its size.

    Perhaps you should reconsider the way in which you are trying to set this up. The method which you are suggesting does not make a lot of logical sense to many of us as there are many more elequant ways of achieving your goal.
     
    Having the same services on two servers does not stop you from running them both off of one public IP. If you set up portfowarding correctly then you can have all of your services on your secondary server run at the same time but on different ports.
    E.G.
    server1 ftp = port 21
    server2 ftp = port 5021
    You can even do this without changing what port it runs on the actual server itself.
    So your local ip:port (e.g. 192.168.0.2:21) does not change.
     
    With the webservers, is there a specific reason why you need two webservers instead of one running multiple virtualhosts?
    You can set up different virtualhosts to respond to different web adresses, e.g. vhost1 respsonds to example.com, vhost2 responds to 1.example.com.
    If you need two webservers, then just use a reverse proxy to forward from your first webserver to the second for a specifc(s) vhosts.
     
     
    Edit: I run one physical server at my home with several linux containers and several virtual machines. A few of my mates use the containers and vms to host things like Minecraft servers, CS:GO/Gmod servers, personal websites and they all use FTP to transfer files. Each of them use a separate container (so they are sandboxed and have different local IPs) but all of the services run off one public IP.
