Supermicro A1SRM-LN7F-2758

  • Hey guys,

    Just wanted to pass along a board that is just coming out: the Supermicro A1SRM-LN7F-2758. Product page is here.

    Key features:

    • 7x Intel gigabit lan: 3x pairs of i354 and i350 NICs + 1x extra i210

    • Atom C2758

    • IPMI

    Did the formal Supermicro A1SRM-LN7F-2758 review this week and thought I would pass along.

    I did run pfsense 2.1.5 on it along with a Hyper-V based pfsense 2.2-BETA. The pre-release sample I got for review certainly looked more like a shipping board than a pre-production sample so they should be available at retail shortly.

  • Thanks for this post, and the review.

    I've been looking for something like this for a very long time. I see Supermicro has the same in a box with power supply. Add a SSD and you have a nice setup. A pair in an active/passive setup and you are topping some extremely high end capabilities with pfSense.

    My question is, did you do any routing testing? I like the Intel NIC's in general, seem very well supported and stable under BSD, but my concern is the Atom CPU. Can it route at over 900Mbit? How many of those 7 ports could it simultaneuosly route at 900Mbit?

    And then finally, any idea as to IPSec performance? I'm hard pressed to get 250Mbit IPSec on an i5 CPU, so I'm guessing this Atom can get what, 50Mbit at best?

    Would appreciate anyone's experience with this.



  • Gonzo posted these results for IPSec on the 7551 - which uses a much weaker (2 core/lower clocked)  rangely cpu

    I'm seeing between 729mbps and 891mbps throughput in the below.

    As for routing over 900mbit, definitely could, across 9 ports? probably - if you take into account there are 8 cores on the board…  Once there is Quickassist support in pfsense, this board will be a beast.

  • Take a look on technical spec:

  • ditto ->

    about half the performance of a xeon 1230v3 while using 1/4 the power.

    this cpu has aes-ni, so it should do far better under 2.2

  • I've been obsessing over this board for a few days now.  I think I'm going to get one.

    Any idea how noisy it is in a 1u setup?  I have a home office, would like to go to a bigger case if that can make it silent or nearly so.  Fanless would be great.
