SR2612UR issues with SATA hard drives

teosinger Community Member
Currently Being Moderated

Hello everyone,

i have a big issue with this new server SR2612UR; once insered the two 3,5" SATA hard drives (Western Digital 2GB Raid edition) into the front RACK unit i can't see them in BIOS. If i connect them directly on the motherboard with sata cables, so without using the MIDPLANE i have no problem and i can use the integrated RAID to perform the mirroring i should do.

 

I've called INTEL for support and they have suggested to buy module AXX4SASMOD to let BIOS see SATA hard drives but no way.

 

As i have to deliver the server at the end of the week my question is, can i remove th MIDPLANE and use my SATA hard drives into RACK with these cables for example

Thank you in advice for any helping answers

    teosnger,

     

    The SR2612UR has specific drive slot number ordering. There is also recommended drive installation when combining SATA and SAS disk drives. See the Intel® Server System SR2612UR Service Guide for more details.

     

    The backplane serves as an interface between the midplane board and the system drives.

     

    The hot-swap backplane provides support for both SAS and SATA hard drives. There are no hard drive cables that connect to the backplane. All hard drive control signals are routed from the midplane board, which plugs directly into the backplane.

     

    For RAID support on the active midplane, you should install an additional RAID controller. See the SR2612UR Spare Parts & Configuration Guide for supported RAID controllers, including the AXX4SASMOD.

    teosnger,

     

    Additionally, as a rule, the onboard server board SATA ports would be used to run the two internal fixed 2.5-inch SATA hard drive bays. The 12 3.5-inch hot-swap hard drive bays would be run via an add-in RAID controller connected to the SAS connector on active mid-plane.

    The midplane has a SAS expander, which can only work with a SAS controller. That's why an add-in SAS controller is required to use the front 12-drive bay. You still can use the onboard SATA ports with the two internal 2.5" drives.

    Hello,

    thanks a lot; have tested connection with AXX4SASMOD today and i've installed Windows Server 2008 RC2 without problems.

     

    Just an issue..every 3-4 seconds the pointer freezes..do you think is an hard disk issue due to the RAID module AXX4SASMOD? I had the same issue trying to install Windows Server 2008 RC directly on SATA ports..

     

    I've performed BIOS update and Windows update but still have this issue; already tried with other RAM Memory modules but nothing changes.

     

    Any ideas?

     

    A big thank you.

    Most likely you're affected by this issue:

     

    High CPU Utilization under Windows 2008 R2 / Windows 7 * with embedded NIC driver

     

    The latest NIC driver should fix the issue.

    Network Drivers need to be updated or PCI AER support needs to be disabled. (bug in embeded driver causes high CPU utilization)

    Hello,

    it was a problem of NIC drivers :-)

     

    I had already solved but really happy to see very fast answers on this Community.

     

    Thanks a lot to everyone!!! :-)

    Please let me kick in a question here.

    I just purchase a 2612UR server, and was disappointed to read that the stated internal 6 port RAID SATA controller should not support the connection on drives directly from the midplane.

    The server comes with a "MiniSAS to 4 SATA port cable" and I assumed that when connecting this between the SAS midplane connector, and the four SATA connectors to the mainboard, I was good to go.

    I have been unable to get the BIOS to recognize any hard drives this way though, either as "Enhanced" drives or as RAID.

     

    Do I have to buy a seperate RAID controller to do this, and if I do, how do I get ALL the 12 drives connected?

    Yes a SAS controller is required to use the 12 drive bays. As I mentioned in my previous post, the backplane has a SAS expander, that's why you need a SAS controller, and also that's how all 12 drives can be used thru 4 ports on the SAS controller. SATA controller does NOT work with expander.

     

    The cable included in the system is for use with RAID controllers with regular SAS/SATA data ports, like AXXROMBSASMR. If you're using a RAID controller with SFF-8087 connector, a different cable is required. Check What cable will I need to hook a RAID controller to the system midplane? and Spares / Parts list and configuration guide.

    See http://download.intel.com/support/motherboards/server/s5520ur/sb/r2612ur_service_guide_14.pdf

     

    The SR2612UR has a SAS expander midplane.

    The mother board has SATA down wich can be used for internal 2.5 inch OS drives.

     

    The 4 port from a SAS controller \ raid card  will pass the data to the SAS expander on the midplane which then expands it to the 12 drives in the system which can be either SAS or SATA. (see population locations rules at teh link above)

     

    A SATA controller can not talk to a SAS device (i.e. the expander) so nothing get passed throught the expander and no drives of any type are found.

     

     

    General rule:

    SAS can talk SAS or SATA

    SATA just talks SATA

    Wait, you want to say, they ship SR2612UR server, with 6 onboard SATA ports for 12 slot 3.5 + 2 slot 2.5 HDD, and you can only use 2 SATA ports for 2.5 HDD/CDROM, leaving rest of 4 SATA ports unused and worthless 12 slot 3.5 HDD rack, if we have not bought additional part?

     

    We currently have SR2612UR server, 12 2TB drives, and Intel RAID RT3WB080 card, and it turns out, we can't start up that server, we need obligatory buy some 2.5 system drive (or CD/Flash memory stick, or any other stuff, that handles boot/system for this server) and another controller, that will allow use those 12 2TB SATA drives... Am I correct?

    Nils,

     

    As Edward has said the SR2612UR has a SAS expander (Active SAS Midplane). The midplane provides SAS connectivity between any attached SAS host adapter and the 12 3.5-inch SAS/SATA hard disk drives located in the front of the enclosure.

     

    The midplane SAS connector to SAS host adapter is through an industry standard MiniSAS connector as defined in SFF-8087.

     

    The key here is "SAS connectivity between any attached SAS host adapter". The onboard connectors are SATA for the two optional 2.5-inch fixed 3Gbps SATA hard drives (inside chassis).

     

    The Intel RAID Controller RT3WB080 you are using is a SATA only RAID controller and is not compatible with the SR2612UR. See the SR2612UR Spare Parts & Configuration Guide for controller compatibility.

     

    You don't need to use the optional 2.5-inch fixed HDDs for your bootable operating system, you could create a bootable array off the 3.5-inch SAS/SATA hard disk drives located in the front of the enclosure. You will need a SAS RAID controller though per the SR2612UR documentation.

    John

    Ok, thanks John. That was a "rake" we stepped on, as such information is not given "stright in face" and documentation lacks many instructions.

     

    But I still don't get, why there is 6 on-board SATA slots, but only 3 of them could be used (2xHDD, 1xCDROM), there is no way to add more devices inside that case.

    Nils,

     

    The Intel® Storage System SR2612UR uses the Intel® Server Board S5520UR. The S5520UR server board can be used in multiple implementations. The SR1600UR, SR1625UR, SR2600UR, SR2625UR and SR2612UR.

     

    Each of these systems has it's own capabilities and requirements that the S5520UR server board provides. Some features of the S5520UR server board are used and some features are not used with each of the systems. It wouldn't be cost effective to design a specific server board for each system and only populating the specific features for each system.

     

    Another example would be processor support. The S5520UR server board supports processors with a TDP of up to 130W. The Intel® Server System SR2612UR only supports processors with a TDP of less than or equal to 95W.

     

    Hope that helps.

     

    Regards,
    John
