ASRock C2750D4I In The Box
Server motherboard packages are almost confusing. On the one hand it is a premium product that should get premium treatment, especially if it is end-user facing rather than server customer facing. The counter argument to this comes from server motherboard users knowing exactly what they want to use, so why waste money adding equipment that might not be applicable? The variation of cases or server chassis mean it is almost pointless to add something like a USB bay or rear bracket.
Nevertheless ASRock offers the following with the C2750D4I:
Driver DVD
Manual
Rear IO Shield
Four SATA Cables
Being a motherboard aimed at storage we should be glad that at least some cables are there, but this is only 1/3 of the number of SATA ports on the motherboard. In a server case I would imagine that all the cables are of appropriate length, and that can be hard to judge – so some is better than none but not as useless as more. If that makes any sense.
Many thanks to...
We must thank the following companies for kindly providing hardware for our test bed:
Thank you to OCZ for providing us with 1250W Gold Power Supplies and SSDs.
Thank you to ADATA for providing us with memory.
Thank you to ASUS for providing us with the AMD HD7970 GPUs and some IO Testing kit.
Thank you to MSI for providing us with the NVIDIA GTX 770 Lightning GPUs.
Also thank you to Silverstone for sending us the DS380 case.

Power Consumption
Power consumption was tested on the system as a whole with a wall meter connected to the OCZ 1250W power supply, while in a single MSI GTX 770 Lightning GPU configuration. This power supply is Gold rated, and as I am in the UK on a 230-240 V supply, leads to ~75% efficiency > 50W, and 90%+ efficiency at 250W, which is suitable for both idle and multi-GPU loading. This method of power reading allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency. These are the real world values that consumers may expect from a typical system (minus the monitor) using this motherboard.
While this method for power measurement may not be ideal, and you feel these numbers are not representative due to the high wattage power supply being used (we use the same PSU to remain consistent over a series of reviews, and the fact that some boards on our test bed get tested with three or four high powered GPUs), the important point to take away is the relationship between the numbers. These boards are all under the same conditions, and thus the differences between them should be easy to spot.
We added in the results from our 25W Kabini platform we are currently testing for a future review, just to show how much difference having the extra controllers and the remote management effects our idle and power loadings. It would therefore reveal that the extra featureset on the C2750D4I equates to 7-10W on our test bed.
Windows 7 POST Time
Different motherboards have different POST sequences before an operating system is initialized. A lot of this is dependent on the board itself, and POST boot time is determined by the controllers on board (and the sequence of how those extras are organized). As part of our testing, we are now going to look at the POST Boot Time - this is the time from pressing the ON button on the computer to when Windows 7 starts loading. (We discount Windows loading as it is highly variable given Windows specific features.) These results are subject to human error, so please allow +/- 1 second in these results.
The issue with remote management systems is always the pre-initialisation time, which on the C2750D4I is unforgiving. However, it is often not a focus of a system such as this which might remain in constant operation for several years without a restart.

I know someone probably pointed this out, but running a default benchmark test against a system that is optimized to work on a dedicated role is a bit pointless. What about some data I/O tests on this one? I didn't see the test you guys take on HDDs/SSDs.trampsvondepalz - Monday, May 12, 2014 - link
I guess the main reason for this product launch is to attack the almost identically featured Supermicro Atom boards (like the A1SRi-2758F) at a somewhat lower pricepoint (which does not necessarily mean "cheap" ! ;-)Supermicro had almost no competitors in this very special segment before - or am I wrong there ?
Let´s wait and see if reliability and software support catch up with the grandmaster of storage & Server boards ! :-)

I may have missed it, but did Ganesh ever test this board?SDLeary

What is the 1U rack mount case - make and model you used here ?
