    Hoping folks have had the time to see the ASUS P9A-I series. Rumor has it that at least one version is coming to North America. Also, rumor has it I may be picking a ASUS P9A-I/C2550/SAS/4L up tomorrow. This is one of the motherboards we previewed here.

    This is the Intel Atom C2550 (4C/ 4T) based motherboard with quad i354 gigabit LAN, and 4x SFF-8087 connectors tied to Marvell 88SE9485 controllers.

    Now, the fun part is that I should get the motherboard Wednesday and will be getting married on Saturday.

    I do plan to have an initial piece up in short order, likely written on the 21+ hour journey to the honeymoon spot. That will mean I need to collect data quickly from the platform. If you do have any requests, please let me know and I will see what I can get done time wise.

    Just arrived in the lab. Will be firing it up soon. In the meantime, I can say it is very similar to the preview piece. The board does look a little bit more brown than in the ASUS site pictures due to all of the PCB traces.

    Have similar question, for example using this or new SM board with onboard 16 SAS ports?

    Very close. Bali.

    I will see on the Supermicro board when I get back.

    Two notes thus far:
    1. I tried booting using a standard Seasonic 650w PSU. Not enough load so it failed. Using a 150w Picopsu now.
    2. The Marvell controllers get HOT!

    Excellent. I will certainly give that a try.

    MSRP - $344 USD

    That is not too bad. It is less than the HighPoint RocketRAID 2740 which also used Marvell 88SE9485 controllers

    Thank you very much for testing this board so close to your wedding and of course: Congratulations on the upcoming wedding.

    If you have any time left a word on energy saving features would be greatly appreciated (I know I am a minority)

    Especially I am interested in whether the board is able to enter standby or hibernate mode.
    And if the on board sas controller is able to do disk spindown.

    Will do my best here. I am cutting it close even for the thermal imaging.

    In terms of power savings here are some data points:
    • BMC only is about 5.8-6.0w of power draw
    • The C2550 is a 14w TDP part.
    • Each Marvell 88SE9485 is 5.5w for a total of 11w
    • My sense is that the RAM is using about 5w
    My takeaway here is that getting power savings is going to be hard given how distributed the power consumption is.

    The rough part is that I could not get the motherboard to work with a Seasonic 650w PSU when I did not use hard drives. It seems like the load was too low.

    Thanks for the fast response. I should perhaps clarify my interest concerning "power savings"
    My questions about the power savings where going more in the direction of the attached spindles.
    And I understand that you probably can't shine much light into that because of the not (with the board) working PSU.

    My current storage server has 32 HDDs attached (as the sas controller can't spin down the HDDs those are eating constantly about 160w.
    So I installed "lights-out" to send the server into standby as long as there is no client online (12-14 hours a day).

    I'm considering this board for a couple of NAS.

    I wonder how does the Marvell compares to LSI SAS 9201-16i or ARC-1320ix-16 for raid Z2 performance.
    Does it supports port expanders? so that we could cascade 16 disks to 1 SFF port on the board, i know in the docs they state 4 disks on 4 SFF for 16 disks, but just wondering as i'm considering using the addonics RAID Tower IX 6G RT93SN6GMS with it.

    Which would be a better performance enhancement on the PCI? A 10g card with TCP offloading or a dedicated non-raid HBA like the ones i mentioned above?

    The voltage should be 3.8w instead right? 5.5w is for the 8 port version of the Marvell 88SE9485.

    I prefer LSI by much. I'm hopeful that they review the Supermicro A1SA7-2750F with LSI onboard.

    I looked at the specs. The asus has 2 of the 8 port versions for 16 total so 5.5 * 2 is right.

    My bad was thinking of the 4 ports and got confused.

    The SM one also looks pretty good for specs too, just wonder how is the performance for the LSI for the price $200+ difference

    Thanks for the notice :) I will straight away buy 2 of them.

    Edit: What is it with newegg and international customers?

    They are not shipping to Europe (except for the UK).
    They would ship to a mail forwarder (i.e. borderlinx) ONLY if I would have a US credit card.
    And they don't ship to a mail forwarder when I try to pay via PayPal, because my address is not in the US.
    They are not taking concierge services.
    They are not accepting up front payment...


    So as it seems I am out of luck.

    Hopefully PC Connection will receive some of the C2750 boards anytime soon.

    I'm not fond of Newegg's return policies but I just ordered one to try.

    My board came in but I can't get it to boot ESXi 5.5, Solaris 12, Open Indiana or any variant of FreeBSD including nanoBSD based FreeNAS. Just hangs wen trying to load the kernel on all these OSes. However is appears to run Linux just fine. I'm kinda at a loss as to what the problem is, perhaps it is a bios issue or I have a bad board? Anyone else try any of these installs with success?

    The Bay Trail-D boards are a bit finicky with ESXi (or vice versa). I just got home and fired up ESXi 5.5 installation media and it did not work. Have a few other things to go do today since it is my first day back in over two weeks.
