ASRock C2750D4I Conclusion
There are many aspects to the C2750D4I that make you sit up and think. The combination of a proper 8-core CPU (even if it is based on Silvermont rather than Haswell) at under 25W powering a GPU capable system with up to twelve SATA drives, dual Intel NICs, up to 64 GB DRAM and management control is merely part of the perspective of this review. The purpose of this motherboard was ultimately cold storage, however many users are finding regular storage uses for it.
Ganesh currently has this motherboard and is more suited to testing the storage aspects of the motherboard than I, however in this review we focused on usability and the package as well as the other system performance.
If we look at the motherboard on paper it makes for interesting reading, and that functionality comes across as positive, however there are a couple of misses. The lack of USB 3.0 might be a cause for concern should a user need to transfer a sizable amount of data that way. The motherboard offers a possibility of a dual NAS/HTPC combination in the home, however the lack of onboard audio means that other methods will have to be used in order to do the HTPC part.
The BIOS and Software stack is server focused, and it is perhaps a shame that more from the channel side was not brought over now that this is a consumer-facing product. The ability to adjust the fans in the OS would be the best place to start, as the management interface fails to offer this and leaves the BIOS as the sole place for configuration. Also updating the BIOS is not as straightforward as ASRock’s channel line.
Having a management interface on a mini-ITX motherboard is rather interesting, especially one that offers control via a Java app and can record what is happening on screen should things go wrong. While it has been said that IPMI is vulnerable to Heartbleed, the interface should not be in a public-facing environment anyway.
Users wanting a storage platform with more than 8/10 SATA devices have in the past needed to invest in a RAID card or something extravagant like ASRock’s Extreme11 series of socketed motherboards or high-end server platforms. Now that the C2750D4I is available for casual purchase at $398, there is that route for home builds. ASRock Rack, the server element of ASRock, needs to develop an understanding of what customer-facing products have to be in order for users to see its products as more than just functional. The choice of Marvell controllers will be bemoaned by some users, especially if the aforementioned reports are prevalent.
When Intel’s next line of Atom-based processors hits the market, I hope ASRock build an updated version in a similar style and take on board the comments of current users. While a niche market, the users in that market are always looking for the ideal system build for their needs and it requires some lateral thinking from the motherboard manufacturers.

Yes, for that price and target market, they should have gone with an LSI chip. You don't see Supermicro or Tyan boards in that price range using Marvell.cen - Tuesday, April 29, 2014 - link
I know it was said that the actual storage review is coming in the future but I think this article is a complete waste of time. You should simply let the storage review happen and not bother with this at all. More than half of the benchmarks are useless, the only ones of value might be encryption and compression.What we actually want to see is FreeNAS thrown in there with a 16TB ZFS zpool and some IO benchmarks. :)

Could be perfect for anyone wishing to build a tiny box for virtualization, a task in which many a NIC, plenty of RAM and a multicore processor is most helpful.RandomUsername3245 - Tuesday, April 29, 2014 - link
I've wondered how one of these Avoton boards would compare to a Supermicro C2xx + Pentum G3430 (which supports ECC). This is the cheaper option if you don't need lots of ports, but once you add $100 for a sata card from Ebay, these options are similarly priced.Calista - Tuesday, April 29, 2014 - link
Could you please measure power consumption without the 770 as well? I have a HP Elite 8200 with a quad i5, SSD + 2.5" HDD, 32 GB RAM and an extra NIC as a makeshift box for ESXi and with 6-8 virtual machines running it draw less than 30 watt. It would be interesting to know how low this machine could go since any machine running 24/7 will add substantially to the power bill.Guspaz - Tuesday, April 29, 2014 - link
If I was using this in my home file server, I'd make a few changes to the board. The number of SATA ports is fine, because even though I've got 18 drives in mine, that PCIe slot lets you put in a SAS/SATA controller to get the total up as high as needed (16 port cards aren't hard to find, higher is available).However, I'd change a few things:
1) Replace the CPU. Home file servers can often be bottlenecked by individual CPU core performance, because not all filesystem operations on ZFS are multithreaded (although it's far better these days). For the ~25W TDP, I would much rather have a Haswell part, even if it meant fewer cores. For that TDP, you could get a ~3GHz dual-core part, or a ~2GHz quad-core part. Either of those would be better suited.
2) Add digital video output. HDMI, DVI, DisplayPort, any of them. I'm not suggesting using this thing for HTPC use, but many monitors these days are digital-only, and nothing is more annoying than trying to diagnose problems with a headless system when your motherboard is VGA-only and all you have is digital-only monitors.
3) Drop two of the RAM slots, and use them for another PCIe slot. Four slots is excessive for anything but enterprise use. Two slots cheaply gets you 16GB of RAM, or 32GB if you're desperate, either of which is more than enough for a home file server. A second PCIe slot, on the other hand, could enable a variety of other options, be they multiple SAS/SATA cards, a discrete video card if you really do want to use the thing as an HTPC, a video capture card (this board in that Silverstone case would probably make a decent HD-SDI recording box), etc.
4) More USB ports, prefereably 3.0. If extra space is needed for the ports, ditch one of the three GigE ports; two is plenty.
5) An mSATA slot for a boot drive could be useful, although it would probably increase board complexity by requiring some of the board components to move to the rear.

"Two slots cheaply gets you 16GB of RAM, or 32GB if you're desperate"My ZFS media rig has 19 drives (21 including the ZIL and l2arc), plus boot media and at 36Tb it _needs_ 32Gb of ram to work efficiently. It kept bottlenecking at 16Gb. The next round of storage will push well past the 32Gb requirement.
+1 on the video output, +1 on usb3 - but I don't think it needs more ports. That's not a good fit for the target, which is a storage controller. Ditto on the mSATA.
If you need fewer cores there's a quad-core version which is cheaper.
I'd prefer that they placed a lsi sas controller onboard and dumped the sata ports for minisas (an expander cable is cheap, tidy and positively locks into place to ensure no problems.) The downside is that a decent sas controller would add at least $100 and a port multiplexer as much again.
If I was designing, I'd think about 10Gb copper, but that adds 15W to the power consumption and $150 to the price.
This thing is expensive for prosumers and limited for enterprise, but compromises are always like that. Supermicro's version has similar issues and the fact that they don't use minisas makes me think that perhaps Intel have placed restrictions on what can be used.

well my zfs rig has 20 2.5" 2tb sata hdds (2x 16tb raidz2). no ZIL. no L2ARC.runs on a single 8GB ecc ddr2 dimm on a sandy bridge i3-2100T.
as a home fileserver this system rocks. it might be ram "bottlenecked" for high i/o tasks, but all i can see is that it performs at least as well as a single USB3 hdd... and it outperforms any consumer nas.

For a NAS or SAN build this seriously lacks 10GbE and USB 3 ports. All in all this board seems like a pretty strange amalgamation of random features, as there're better choices for about any possible use case around.Gunbuster - Tuesday, April 29, 2014 - link
14000 RPM Delta fans? No Thanks!I would have called it the AssRack. Sorry I couldn't resist!
