Well, its looking quite bleak to be honest. As you mentioned, intels server configurator doesn't list that controller (or any other except for Intel ones!) and in LSI's compatibility list for the controller (http://www.lsi.com/downloads/Public/RAID%20Controllers/RAID%20Controllers%20Common%20Files/MegaRAID_Value_Feature_Interop_List_SAS2.pdf) the S2600CP2 isn't listed. The closest to your board is the S2600GZ or S2600GL, but they are of course different.
Don't take it as definitive advice but, in my opinion, try to get a refund or exchange asap for the controller.
I hope this is of help.
this Server is turning out to be a big pain in the neck.
I send back the LSI controller and bought a supported on from Intel:
the INTEL RS2WC040 Raid Controller. according to the ARK (what ever that means) of my board it should be compatable. but its seems not to. after Board Overview it directly goes to the DVD or LAN boot order.
No Bios of Raidcontroller avaiable.
I think this new Hardware with Sockel2011 is just to young and has to much bugs.
But I assume that when intel states this controller is compatable to this board then they have tested it.
That gives me hope in this case. Unfortnatly for the time I have spend compared to the money I saved to self-assembly its a zero-win outcome ....
Maybe I have to switch any jumper on the board or maybe I have to set anything wierd in the Bios to be able to see the Bios of the RaidController.
you have to put the Raid-Controller in the first PCIe Slot (the long one with 16x) the others will not work....
next problem d**n chenbro backplane seems not to be compatible with the Raidcontroller.
Ill give a **** on hot swap and I'll connect those drive without backplane.
man what a journey.
I'll give you a final Update when EXSi is running
