5 out of 5 eggsGreat board for NAS

Pros: Perfect board for NAS or small vhost!

Small, quiet, 8 cores, up to 64gb RAM, virtualization support, great performance/watt, quad Intel gig ethernet, crypto/compression accelerator (C2758 only), built-in IP KVM and other server-grade features!

Supermicro support on top of Newegg service!

Board is dead-silent and even when running full-bore on the bench with no air circulation it only hit 75C - it got hot, but never came close to the 90 degree C max temp.

Installed in a Node 304 case with normal airflow and system load it rarely exceeds 36C and idles at 36 watts. Under full load it can reach ~40C and ~50 watts.

Cons: First board was bad.

Other Thoughts: First board was bad, but Newegg swapped the board without hassle. Used shoprunner so got free shipping. Supermicro would cross-ship a replacement if I'd needed the board immediately.

The ATOM C2758 isn't as fast as new D-1540 low-power Xeon's, but is enormously cheaper and is still lower power. Newer Xeon's are on the way with 25W TDP but they're not out yet, and it's unknown what performance compromise was made to hit that low TDP rating.

Very happy with this board.

5 out of 5 eggsGreat Board

Pros: Great Performace.
Used it as an iptables router and firewall
Low Power.
Low Heat

Cons: No Documentation!!!!
I don't think 16GB ECC SO-DIMMS exist, so don't expect to reach 64GB

Other Thoughts: The board comes with a 4 pin CPU connector AND a 24 pin ATX. The case that the board ships stock with (I chose to buy them separately) only comes with a 20 pin ATX connector , NOT a 24, and NO 4pin CPU connector. The board still works completely fine running only on a 20pin ATX. Took me awhile to realize that only a 20 pin is needed.

5 out of 5 eggsNice little board

Pros: 8 cores, vt-x support, passively cooled.

Cons: wish vt-d was supported on atom

Other Thoughts: built 4 of these for little virtualization cluster - zero problems. Read the instructions : you shouldn't plug in the 4 pin next to the 24 pin ATX. I did by mistake but nothing bad happened (I hope). I since unplugged 4 pin and all is fine.

4 out of 5 eggsD Livesay

Pros: it works.
it was my first supermicro board and it won't be the last. boots a little slow but has lots of options. recognized everything and had NO issues what so ever. nice to have internal usb A plug on board just wish the other header was that way but got header usb 3 adapter and is humming along.

Cons: Sata 3 only two with 4 sata 2
NO VD-T support this i am very mad about. i might not of purchased this board if i had done more homework.
has Marvell Nic Transceiver (YUCK)

Other Thoughts: Board is humming along with 5 2 TB reds two usb's and one 240GB Kingston HyperX wit ESXI, PFSense and FreeNAS.
be sure to change your MBuf's in PFsense immediately of it will panic and freeze with four nic's

5 out of 5 eggsSolid Cool Low Power Hyper-V Box

Pros: Easy install, effective solution, small form factor. Works with a bunch of stuff. Have 2 Windows 2012 R2 servers running on Hyper-V 2012 R2, nary a single hiccup. Runs great.

Cons: Not really any. People may say price, but for my build and use, couldn't be a better fit.

5 out of 5 eggsUsed to it by now

Pros: Great low-power server board. Enough network interfaces to bond against mulitple sub-nets. Stays cool given a minimal amount of air flow.

Cons: None really. I had some issues with this board when it was first released, and had to RMA it twice; once to due a BIOS bug and a second time due to a combination of inexperience, both my own and SuperMicro's, as their support wasn't famliar with this model board.

Other Thoughts: A little slow to post, but rock solid once it's up. Currently it's my home servuces server, exporting a 10TB RAID6 over NFS and handling DNS, NTP, and proxy duties. If you have simliar requirements I would recommend it; if you need a little more wait for the X10SDV-TLN4F or one of it's brethren.

5 out of 5 eggsLove it!

Pros: Low power
8 cores

Cons: Expensive

Other Thoughts: This chip is powerful. I'm running unRaid 6.0-beta12 + 12 dockers, including mysql and plex servers. System is fast and responsive. Loading media through XBMC takes only couple seconds (spin up). No problem watching movies on TV, PC and tablet at the same time over LAN. No buffering issues at all. The same applies to Plex. Server is capable to encode video file at 2x speed. That means that 60 minutes video will be encoded in 30 minutes. I tested it with WTV files recorded by Ceton tuners and other HD mkv files. Plex Sync converted them to mp4 format. To give an idea, atom D510 takes 10 minutes to convert 60 minutes of wma audio file to mp3. I did a test to see how it performs when other tasks are run? During unpacking and running PAR files (nzb) plex encoding was jumping between 1x and 2x. But when system is not performing any other activities, encoding remains constant 2x. Streaming outside of LAN over local Starbucks wi-fi was not an issue. My upload speed is 5 Mbps. It took about 3-5 seconds for a video to start to play. Fast forward is responsive and movie plays within 1-2 seconds. I noticed that adjusting Plex streaming quality (inside app) to a movie resolution gives the best results. I tested playback for both 720p and 1080p mkv’s DTS audio tracks and I did not encountered any playback issues.

CPU utilization during video encoding and unpacking + repairing downloaded files jumps between 50%-70%

4 out of 5 eggsWorks with pfSense after fix

Pros: Let me save you some time if you are using this with pfSense and see the fix below in other thoughts.

Cons: NICs crash with pfSense initially.

Other Thoughts: I used this for a pfSense box. NICs would seem to crash after a few minutes. See intel igb fix.

4 out of 5 eggsFreeNAS

Pros: Quiet. Runs cool enough to keep in my closet with my switch. I use this with VMware 5.5 free to run a pfsense firewall, a FreeNAS home backup, and still have room to use as test bench for virtual projects at work. I can saturate two 1 GB NICs when maxing out FreeNAS. Has IPMI NIC additionally and you can set up all software without installing DVD on box itself. Mine has been up and running several months without single reset and stable. USB on motherboard for running VMware without worry of it getting knocked out of slot.

Cons: I could have used more SATA ports
It runs pretty warm when stressed, I added quiet fan to blow over processor.
My free VMware 5.5 did not recognize I350 NICs and need to be modified (lots of help online).

Other Thoughts: 1 processor, 8 cores, 8 logical cores (no hyper threading)
These are efficient enough for me not to feel like total heal for keeping a computer running 24/7. I tried this for SQL server in Windows 2012 and it felt pretty sluggish even with SSDs but it did run. For my BSD based FreeNAS and pfsense it is perfect and fast enough to saturate my NICs which is fast as I could hope for.

4 out of 5 eggsPerformance -had to return

Pros: perfect for a regular server

Cons: ESXi 5.5 does not Recognize the onboad NIC. but I did not take time to check if I got a defective board
POST load slowly, and get stuck a few times.. this was enough for me to return

Other Thoughts: I was a bit disappointed to return, bought it only for a test Lab, since it had such great review with ESXi . ESXi5.5 did not see the onboard NIC and the BIOS stuck/freeze a few times and had a hard time seeing a DVD/CD ROM drive
I did not try to Flash the BIOS so as not to void the warranty.
