My first own rack-mounted NAS

    • My first own rack-mounted NAS

      As every new user should do, they should make a thread first in this section! So this will be my first post!

      So here is the story of my first build:
      1. I finally moved out of my parents place (finally time, stayed way to long at home... ...although it was very good there). They have a NAS, which I maintain the whole thing, but my parents still use it. So I couldn't take it with me. I had to make my own new NAS and I wanted to 'make' my own, and not use a prebuilt system (much more fun).
      2. I started to search for an OS. A few years ago I heard about FreeNAS, so I first looked for that, but then saw the specs they ask for could be expensive and difficult to find. I searched for alternatives and stumbled on OpenMediaVault. Much more lightweight, easy and big community and of course I chose OMV!
      3. In my small new home, I found space to put a rack for all my network-hardware. I had 4U free space in the rack and searched for a chassis which would fit. That is how I found the chassis (see for specs lower).
      4. I wanted it to be power-efficiënt in some way (because Climate Change is not a HOAX) and therefore I wanted to choose the parts in function of it.
      5. I'm a beginner when it comes to everything with Linux-based systems. Already used a Raspberry Pi to fiddle around with, but only basic stuff.
      Specs:
      • Chassis: Inter-tech 2U 2404S
        • 2U rackmountable chassis, without being to deep
        • 4 hot-swapable harddrives.
        • µATX motherboard (cheaper than m-ITX)
        • supports ATX PSU form-factor, but not standard ATX, without modding. The current ATX PSU take their ventilation from the bottom, but this chassis doesn't support it for the ATX PSU. I modded the mounting bracket so it could fit a SFX PSU.
        • Had to add 4x 50mm fans for Better cooling with lower noise.
        • not so cheap :( , but only chassis, which fitted my needs.
      • Power Supply Unit: Corsair SF450 Platinum
        • Smallest Wattage (450W) for a PSU with Platinum certification.
        • Fits the Chassis
        • Needed some CableMod extension kit
      • Processor: Intel Core i3-8350K (second hand, underclocked and undervolted)
        • First I wanted to buy one of those T-variants Intel sells, because of their low voltage usage. I had the Intel Pentium Gold G5400T or G5420T (which will come out later) in mind.
        • But a friend of mine had a spare Intel Core i3-8350K and could sell it to me for a good price.
        • Clocked it like an Intel Core i3-8300T for low power usage (already done and tested)
        • Has an iGPU, so no need for extra Graphics Card.
      • CPU-Cooler: Cryorig C7
        • Relatively cheap, but could handle an overclocked Intel Core i3-8350K if needed.
        • Fits the chassis in height.
      • Motherboard: ASRock Z370M Pro4
        • Searched for the cheapest microATX-board with under- or over-clocking possibilities that supported the cheap CPU I got.
        • Supported more than 4 hard drives.
        • Possibility to upgrade later with 4 PCIe card-slots (example: faster network card)
      • Memory: 2x G.Skill TridentZ DDR4-2800 4GB
        • 8GB Ram in total, dual channel
        • again second hand from the same friend as the processor
        • For the chassis, it was better to take low-profile Memory-sticks. I to put them in slot 1 and 3, in stead of the recommended 2 and 4, but they still work dual channel.
      • Storage: (most important and expensive part)
      It is already built physically, and will be used for normal storage, plex server, virtualisation,... (will see where we'll get :D ). Next: trying to get the Server working...

      Do you mind posting a picture of your rack?
      Nope, if that interests you... but not all the connections on the patch-panel are connected to both switches yet (1 managed, 1 unmanaged but with PoE).
      The Rack


      The cupboard: it is in the hallway at the entrance so the wife doesn't see it :D

      Nice.
      Note that a small Bronze is more efficient than a large Platinum at the low power you need.
      I know PSU's are the most power efficient around 50%-60% of their power. So a 300W would be better, but almost only bronze or worse are available in SFX. (Or i needed to mod the chassis in an other, more difficult way to make it all ATX PSU's compatible.) But the 450W platinum is not that bad either (87% to 92% depending on the load), but has the advantage I could add more component later on. Now it is expandable.
      But you're right.


      And I got my first problem (after updating windows on my old laptop):

      Searching why... I found this post: forum.openmediavault.org/index…o-locate-CIFS-SMB-shares/

      But that's for tomorrow.
