Supermicro X10SDV-F Build; Datacenter in a Box

I don’t have room for a couple of rackmount servers anymore so I was thinking of ways to reduce the footprint and noise from my servers.  I’ve been very happy with Supermicro hardware so here’s my Supermicro Mini-ITX Datacenter in a box build.

Supermicro Microtower

Supermicro X10SDV Motherboard

Unlike most processors, the Xeon D is SOC (System on Chip) meaning that it’s built into the motherboard.  Depending on your compute needs, you’ve got a lot of pricing / power flexibility with the Mini-ITX Supermicro X10SDV motherboards with the Xeon D SOC CPU ranging from a budget build of 2 cores to a ridiculous 16 cores rivaling high end Xeon E5 class processors!

How many cores do you want?  CPU/Motherbord Options

x10sdv-4c-tln2f_spec Supermicro board with fan

A few things to keep in mind when choosing a board.  Some come with a FAN (normally indicated by a + after the core count), some don’t.  I suggest getting it with a fan unless you’re putting some serious air flow (such as with a 1U server) through the heatsink.  I got one without a fan and had to do a Noctua mod (below).

Many versions of this board are rated for 7-years lifespan which means they have components designed to last longer than most boards!  Usually computers go obsolete before they die anyway, but it’s nice to have that option if you’re looking for a permanent solution.  A VMware / NAS server that’ll last you 7-years isn’t bad at all!

On the last 5 digits, you’ll see two options: “-TLN2F” and “-TLN4F” this refers to the number network Ethernet ports (N2 comes with 2 x gigabit ports, and N4 usually comes with 2 gigabit plus 2 x 10 gigabit ports).  10 gbe ports may come in handy for storage, and also having 4 ports may be useful if you’re going to run a router VM such as pfSense.

I bought the first model just known as the “X10SDV-F” which comes with 8 cores and 2 gigabit network ports.  This board looks like it’s designed for high density computing.  It’s like cramming dual Xeon E5’s into a Mini-ITX board.  The Xeon D-1540 will well outperform the Xeon E3-1230v3 in most tests, can handle up to 128GB memory, two nics (this also comes in a model that offers two more 10Gbe providing four nics), IPMI, 6 SATA-3 ports, a PCI-E slot, and an M.2 slot.

IPMI / KVM Over-IP / Out of Band Management

One of the great features of these motherboards is you will never need to plug in a keyboard, mouse, or monitor.  In addition to the 2 or 4 normal Ethernet ports, there is one port off to the side, the management port.  Unlike HP iLO, this is a free feature on the Supermicro motherboards.  The IPMI interface will get a DHCP address. You can download the Free IPMIView software from Supermicro, or use the Android app to scan your network for the IP address.  Login as ADMIN / ADMIN (be sure to change the password).

Supermicro IPMI KVM over IP

You can even reset or power off, and even if the power is off you can power on the server remotely.


Supermicro KVM

And of course you also get KVM over IP, which is so low level you can get into the BIOS and even load an ISO file from your workstation to boot off of over the network!

When I first saw IPMI I made sure all my new servers have it.  I hate messing around with keyboards and mice and monitors and I don’t have room for a hardware based KVM solution.  This out of band management port is the perfect answer.  And the best part is the ability to manage your server from remote.  I have used this to power on servers and load ISO files in California from Idaho.

I should note that I would not be exposing the IPMI port over the internet, make sure it’s on it’s behind a firewall accessible only through VPN.

Cooling issue | heatsink not enough

The first boot was fine but it crashed after about 5 minutes while I was in the BIOS setup…. after a few resets I couldn’t even get it to post.  I finally realized the CPU was getting too hot.  Supermicro probably meant for this model to be in a 1U case with good air flow.  The X10SDV-TLN4F is a little extra but it comes with a CPU fan in addition to the 10Gbe network adapters so keep that in mind if you’re trying to decide between the two boards.

Noctua to the Rescue

I couldn’t find a CPU fan designed to fit this particular socket, so I bought a 60MM Noctua.

60MM Noctua Fan

This is my first Noctua fan and I think it’s the nicest fan I’ve ever owned.  It came packaged with screws, rubber leg things, an extension cord, a molex power adapter, and two noise reducer cables that slow the fan down a bit.  I actually can’t even hear the fan running at normal speed.

Notcua Fan on Xeon D-1540

There’s not really a good way to screw the fan and the heatsink into the motherboard together, but I took the four rubber things and sort of tucked them under the heatsink screws.  This is  surprisingly a secure fit, it’s not ideal but the fan is not going to go anywhere.

Supermicro CSE-721TQ-250B

This is what you would expect from Supermicro, a quality server-grade case.  It comes with a 250 watt 80 plus power supply.  Four 3.5″ hotswap bays, trays are the same as you would find on a 16 bay enterprise chassis.  Also it comes with labels numbered from 0 to 4 so you could choose to label starting at 0 (the right way) or 1.  It is designed to fit two fixed 2.5″ drives, one on the side of the HDD cage, and the other can be used on top instead of an optical drive.

The case is roomy enough to work with, I had no trouble adding an IBM ServerRAID M1015 / LSI  9220-8i



I took this shot just to note that if you could figure out a way to secure an extra drive, there is room to fit three drives, or perhaps two drives even with an optical drive, you’d have to use a Y-splitter to power it.  I should also note that you could use the M.2. slot to add another SSD.


The case is pretty quiet, I cannot hear it at all with my other computers running in the same room so I’m not sure how much noise it makes.

This case reminds me of the HP Microserver Gen8 and is probably about the same size and quality but I think a little more roomier and with Supermicro IPMI is free.

Compared to the Silverstone DS380 the Supermicro CS721 is a more compact.  The DS380 has the advantage of being able to hold more drives.  The DS380 can fit 8 3.5″ or 2.5″ in hotswap bays plus an additional four 2.5″ fixed in a cage.  Between the two cases I much prefer the Supermicro CS-721 even with less drive capacity.  The DS380 has vibration issues with all the drives populated, and it’s also not as easy to work with.  The CS-721 looks and feels much higher quality.


Storage Capacity

cs721_open_doorI loaded mine with two Intel DC S3700 SSDs and 4 x 6TB drives in RAID-Z (RAID-5) the case can provide up to 18TB of storage which is a good amount for any data hoarder wanting to get started.

Other Thoughts

cs721_frontI’m pretty happy with the build, I really like how much power you can get into a microserver these days.  My build has 8 cores (16 threads) and up to 128GB memory, and even up to 18TB of data.  With VMware and ZFS you could run a small datacenter from a box under your desk.

I should be posting some ZFS benchmarks on this build shortly.

  2. That’s one fantastic little rig you’ve got there! I love that mini chasis, iXsystems has the FreeNas mini based on the same thing. Personally, I’ve gone back to full sized chasis because they’re so cheap and quite.

  3. Ben,

    Good read, thanks for sharing. I just bought a SuperMicro 5028D-TN4T and it’s blazing fast, I’m running my full VM test lab and it’s hardly noticed. I do have a question about the IMPI, I’m used to going the HP Microserver route and there’s really no configuration needed, just enter a license key, I’m quite lost with the SuperMicro IMPI and SD5 setup, is that something you’d be open to helping (consulting fee, of course) with? I’m not sure how to contact you via the PGP contact you have on your site, please let me know the best way to reach out, if that’s in your wheelhouse.



  4. This looks like a really good build, but I have one question.
    Given that the motherboard has 6 SATA3 connections and you don’t appear to need more than that (unless you are actually using three 2.5 drives); why did you install an external HBA?

    • Hi, Gareth. The only reason was I was runing a ZFS NAS server inside VMware, and the best way to do that is to pass an HBA controller to the guest VM running ZFS so that it has direct access to the disks. Probably a more efficient use of hardware is to run a type-2 hypervisor like KVM or bhyve on top of OmniOS or FreeBSD so that the hypervisor has direct access to ZFS storage and no need for an HBA.

      • Thanks, Ben
        After I posted, I figured that may be the reason. I too had been thinking along the napp-it route but once I saw your articles about bhyve and the responses about Joyent, I’m starting to reconsider that decision.

  6. I have the generic version of this case. Its the Ablecom CS-M50.
    UK price was about 105ukp, whichs is cheaper than Supermicro :)

    I did read somewhere that Ablecom supply it to Supermicro who rebrand it, but can’t find the link right now…

    • Hi, Lucien. I don’t have the system up and running at the moment, but I’ll let you know next time I’m doing some experiments on it.

  7. Why didn’t you get the the motherboard model with the fan? It’s only $10 more. Granted you probably bought the wrong model, you could’ve ordered the oem fan from supermicro.

    • Good question. I didn’t realize the airflow from the case fan wouldn’t be enough, and at the time I bought it the model with the fan wasn’t available yet–and I saw this listed for $780 at a time when it was hard to even find them in stock for any price. I’m happy with what I got for the price, but unless you’re putting this in a server chassis it’s better to have the one with the fan.

      I didn’t realize you could buy the OEM fan from supermicro? Do you by chance know the part number?

  8. I am so infinitely f’n sad right now I could cry. I seriously just dropped a bunch converting a Lenovo TS140 in to a 4U rack server with a bunch of extra parts I picked up. This makes me want to cry… Good job, dude. This is amazing. I want to do this now.

    • Hi, Chris. Keep your TS140 and buy a second server. I always have at least two servers–one I can experiment with and one that I consider my production environment. The TS140 isn’t a bad system, it’s very inexpensive for what you get so it’s an excellent value, and seems to be rated highly on Amazon. One way to look at it is you could get two or three TS140s very cheaply and experiment with high availability, distributed file-systems, etc. I’ve used a fair amount of hardware (although I have not ever had a Lenovo server) and Supermicro is my favorite so far because it’s inexpensive but server-grade hardware with features I want like KVM over IP.

  9. I ran into similar issues with cooling b/c mine was 60-65 C under full load. I ended up having custom 70 mm x 70 mm x 40 mm heatsinks made that dropped the full-load temps to 48-53 C.

  10. Have you ever tried to use the internal SATA ports with ESXi 6? Did they work too, under VMware and with DirectPath?

  11. THANK YOU for the hint on the Noctua. I realised pretty quick that cooling wasn’t an issue but wasn’t sure what to do about it.

    FYI you can also buy SNK-C0057A4L, the fan + heatsink assembly that comes on some of the other SM Xeon D motherboards. I’ve ordered one and can update here if any one cares.

  12. Hi, Lucien. I just saw this again and realize I didn’t respond. I ran it for 30 minutes of sustained max CPU load (maxing out 8 cores / 16GHz) and here are the temperatures:

    CPU: 84C
    System Temp: 36C
    Peripheral Temp: 42C
    Memory DIMMA: 47C
    Memiry DIMMB: 49C
    FAN3 1700 RPM
    FAN1 3300 RPM

    The ambient temperature in my office is probably around 20-21C

    This seems to be normal per:

    I’d be curious to know how this compares to the stock CPU fan.

  13. Great tip about the Noctua fan! Haven’t ordered yet, but plan to. Going to be doing some swapping around of boards. Started out with a system 5028D with the X10SDV-TLN4F (original Xeon D-1540) in that CSE-721TQ-250B and so far all is great. Doing an all-in-one with ESXi 6.0.0(U2), some nested ESXi instances + VCSA, and a NexentaStor 4.0.4 CE for iSCSI & NFS for labbing vSphere.

    Want to separate the IP Storage from the rest, though, and bought a CSE-504-203B and X10SDV-4C-TLN2f (Xeon D-1521). Right now, the new MB is in the 1RU case and running hottish (60C Idle, havne’t pushed it yet). Have qty. 2 28x40mm PWM fans installed in fan bracket at front of the 1RU case. Question: Is it best to orient for airflow to pull cool air into the case, or exhaust hot air out the case, or does that depend on orientation of the board with respect to Rear-I/O (as with my case) or Front-I/O? Either way, I’m planning to pick up one of these Noctua fans…hopefully there’s enough clearance in the 1RU form factor for it. But in the end my plan is to swap the D-1541 board into the 1RU and just have it serve the Hypervisor(s) role, and put the D-1521 board into the 4-bay case where it’ll just be a NAS/SAN that I can run and forget about.

  14. Hello Ben

    Nice post!

    I am planning to build one with 721TQ-250B and X10SDV-TLN4F. But after comparing the part list of 721TQ-250B + X10SDV-TLN4F with 5028D-TN4T, I noticed some cables are missing

    * X10SDV-TLN4F:
    * 721TQ-250B:
    * 5028D-TN4T:

    Superserver 5028D-TN4T has some extra SATA S-S cables, and 1 CBL-0157L (8 pin to 8 pin ribbon SGPIO cable with tube , 40cm, PBF for SES-II).

    SATA cables are easy to get. But I may have to buy CBL-0157L from abroad. Do you think it is a must? Do you have any problem with the cabling?

    • So, I am actually using an M1015 flashed to IT mode on mine for the disks, I couldn’t be 100% sure but I just looked in my motherboard box and don’t see that cable in it. So likely you’ll need to purchase the cable separately if you need SES-II capability. I see that cable available at a lot of stores in the U.S. including Amazon and Ebay, I’m guessing you’re in another country? I don’t have any issues not using it. With only four drives it shouldn’t be too hard to keep track of. I use FreeNAS so when I built the pool I inserted one drive at a time, labeled the drives slot 0 through 3 in the GUI (to match the numbers on the drive caddies) so it’s easy to know what failed.
