    Hello,

    I am looking for a quiet and energy-efficient home server in a rack housing. I would use it to learn hyper V and VMware virtualization.
    I was thinking about Dell R210, but I`m afraid it will be too noisy in a small apartment. What model can you recommend?

    Look for something similar, but in a tower case (usually neither the processor nor the case itself has a fan).
    The rack-mount ones have fans so small and in such quantity that when you get tired of them, the howler fires up so much that you can`t sit still in the room with it.

    Compatibility of newer versions is a processor issue.
    I couldn`t upgrade to 6.7 on a several-year-old server, but an even older HP laptop had no problem with it.
    I don`t think you need a server, just a PC with more RAM and an appropriate processor.

    Rack and quiet? With these small fans it will always be noisy.
    There are passive cases for desktop and home computers - basically, they are one large heat sink. There are no typical server alds.

    I would rather suggest something like this: Allegro Offer number: 9450728514
    This proposal has a double power supply (power consumption), but you can look for something else with a "normal" single power supply.
    I`m more interested in showing you what it looks like inside - a passive processor, the case itself without a fan.
    And an additional question is where you will keep it in terms of climatic conditions (room, living room, basement, attic, etc.) - this is a passive server, but they work in a strictly defined environment, which in such a case is created in the server room itself (temperature, air humidity) - in this case, you do not have to worry about heat exchange because air circulation is maintained in the server room itself.
    To conclude - I would not go for completely passive solutions, but leave some possibility of installing a fan, at least on the casing. A 12 or 14 cm valve does not spin as terribly fast as those rack jets.

    This Dell is interesting, but I`m afraid it will be power-hungry. I want the equipment to work 24 hours a day. I was thinking about virtualizing the Sophos xg home software, and viewing the reports. See what it looks like in practice. I would also like to set up an exchange server to check how such a mail server is operated. That`s why I want the power consumption to be as low as possible.

    Wait, you need a quiet computer in a rack case - each server will be rather quiet and not very energy efficient (especially when we are talking about post-lease users).
    A better solution is to buy a rack case and put a desktop motherboard + processor inside.
    Moreover, learning hyper-v or VMware on one server makes no sense (unless you nest virtualization, but then the server makes no sense).
    And the one from auction 9450728514 - it is neither energy-saving (and not because of two power supplies - it doesn`t really matter - TDP 95W processor) or rack-mount.
    I had 3 "servers" based on C2558 to learn (but these were the times of ESX 6.0 - 6.5)

    Or maybe instead, some ready-made Mabo with SoC? - the casing is used, the frame is the same, the power supply does not have to be of the high-end class and the power of 1kW is used, there is also a used disk for it, and also a used device.
    Here is a link to see what I mean:

    I had a Dell T110 16GB RAM with a 4-port Intel card. The size of a regular PC and grows like a PC-et ;)

    I chose HP Microserver Gen10 - quiet, efficient equipment.

Topic summary

✨ The discussion revolves around finding a quiet and energy-efficient server suitable for learning Hyper-V and VMware virtualization in a home environment. The Dell R210 is initially considered, but concerns about its noise levels in a small apartment arise. Participants suggest alternatives, emphasizing that rack-mounted servers typically have noisy fans and may not be energy-efficient. Recommendations include looking for tower cases or desktop solutions, such as the Primergy TX120 S3P and HP Microserver Gen10+, which are noted for being quieter and more efficient. The importance of compatibility with newer virtualization software versions is also highlighted, along with the suggestion that a desktop PC with sufficient RAM and a suitable processor might suffice for learning purposes.

FAQ

TL;DR: For quiet home labs, avoid 1U racks with 95W TDP CPUs; “learning hyper‑v or VMware on one server makes no sense.” Use desktop/SoC builds in rack cases and verify ESXi CPU support. [Elektroda, mick1, post #19011330]

Why it matters: This FAQ helps home‑lab builders in small apartments pick quiet, energy‑efficient gear that still runs Hyper‑V or VMware reliably.

Quick Facts

Is a Dell R210 or other 1U rack server quiet enough for an apartment?

Usually not. 1U chassis use multiple small, high‑RPM fans. They get loud fast under load. One member noted the “howler fires up so much that you can’t sit still in the room.” Consider tower cases or rackmount cases with large, slow fans instead. [Elektroda, KOCUREK1970, post #18954320]

What’s a quieter, low‑power alternative to a 1U rack server?

Use a rack case with a desktop motherboard and low‑TDP CPU, or an embedded SoC board. Large 120–140 mm case fans move air quietly. One user trained on three C2558‑based boxes during ESXi 6.0–6.5. That approach balances noise, power, and learning goals well. [Elektroda, mick1, post #19011330]

Do I need a “real server” to learn Hyper‑V or VMware?

No. A standard PC with enough RAM and a compatible processor works fine for learning. Add a reliable NIC if needed. Focus on CPU features and memory capacity for multiple VMs. “I don’t think you need a server, just a PC with more RAM and an appropriate processor.” [Elektroda, pitron, post #18974111]

How do I check if my hardware supports the ESXi version I want?

Use the VMware Compatibility Guide for CPUs and platforms. 1) Identify your exact CPU model. 2) Search the VMware guide for supported ESXi versions. 3) Adjust plans if your CPU lacks required features. This avoids install or upgrade failures later. [Elektroda, jprzedworski, post #18954373]

Why did my older box fail to upgrade to ESXi 6.7?

CPU feature support often blocks upgrades. Some older servers lack required instruction sets, while even older laptops may pass. “Compatibility of newer versions is a processor issue.” Verify CPU support on the VMware guide before trying again. Replace or repurpose unsupported hosts. [Elektroda, pitron, post #18974111]

Is the Fujitsu Primergy TX120 S3p a good quiet lab choice?

It can work, but verify CPU support for your ESXi target version first. Age matters more than the brand here. Check the VMware guide for compatibility, then assess fan noise and storage needs. Prioritize low‑TDP CPUs and quiet cooling. [Elektroda, jprzedworski, post #18954373]

Do redundant power supplies meaningfully raise home power use?

Not by themselves. The bigger factor is CPU TDP and system load. One example cited a 95W CPU as the main energy concern, not the dual PSUs. Choose efficient CPUs and right‑size the platform. [Elektroda, mick1, post #19011330]

Can I learn clustering, HA, or vMotion with one host?

Not fully. “Learning hyper‑v or VMware on one server makes no sense.” You can use nested virtualization for concepts, but features like HA need multiple hosts. Start with two small, efficient boxes if possible. [Elektroda, mick1, post #19011330]

Any proven quiet prebuilt options for 24/7 apartment use?

Yes. The HP MicroServer Gen10 was reported as quiet and efficient in continuous operation. It’s compact, supports multiple drives, and suits firewall, NAS, or lab roles. Validate CPU support for your hypervisor target first. [Elektroda, xendenn, post #19540770]

Are fully passive builds safe for living rooms?

Be careful. Passive servers assume controlled datacenter airflow and climate. Add at least one large, slow case fan for safety. “I would not go for completely passive solutions.” Monitor thermals and dust. [Elektroda, KOCUREK1970, post #18975338]

What simple, quiet setup have others used successfully?

A Dell T110 with 16 GB RAM and a 4‑port Intel NIC worked well and behaved like a PC. Expand gradually as you learn. This balances cost, noise, and functionality for labs. [Elektroda, MrGruffi, post #19012176]

Why do rack servers get so loud under load?

Small fans spin at very high RPM to move enough air in shallow chassis. That design prioritizes density over acoustics. As one expert put it, “Rack and quiet? With these small fans it will always be noisy.” [Elektroda, m.jastrzebski, post #18974578]

Which CPUs are safer bets for low‑power learning boxes?

Favor embedded/SoC boards or low‑TDP desktop CPUs over high‑TDP parts. They simplify cooling, reduce noise, and cut power bills. A ready‑made motherboard with SoC is a practical, quiet foundation for a lab node. [Elektroda, KOCUREK1970, post #19011730]

How should I rack‑mount a quiet DIY lab build?

Put a desktop motherboard and efficient CPU into a rack case. Use large, slow fans and a single efficient PSU. This delivers rack aesthetics with PC‑class acoustics and power draw. Avoid 1U where possible. [Elektroda, mick1, post #19011330]
