    Ok once again... I hooked up the lowest SFF-8484 to the 9211-8i and its working fine with 4x4TB at 6g... So do you think I can safely connect the other two 8484 to another 9211-8i or is it a bit more Complex when it was designed to work with a Sas Expander. There is not much to find for the Backplane itself: Xyratex 92883-01 I really would appreciate any advice cause I don't want to waste too much time and money...

    Hello linustechtips world! My first post shows how naive a human playing with tech can be ; ( I'm quite a noob in Serverthingitech coming from Macintosh Startingpoint is an IBM HS-1235E 12-Bay Storage Server (better Documented as SSR212MC2) / Goal was (maybe is still) Freenas iSCSI Target over 10Gbe So at first everything was running well just to find out that my 4TB Drives will be recognized as 2TB due to SAS1. The System has an SAS Expander connecting the S5000PSL Motherboard (4xSAS/SATA -> SFF-8087-> PM8388 SXP 24×3G) Wouldn't mind the 3g but the 2TB limit makes it more or less unusable. Long Story short as the Backplane presents 3x SFF-8484 with the Expander removed I bought: Dell PERC H310 PCI-e SAS Controller 0HV52W / LSI 9211-8i (IT-mode) 2x SFF-8087 to SFF-8484 1x SFF-8484 to 4x SATA (was not involved yet) Then I fired it up with the with the 9211-8i connected to the Lowest and middle SFF-8484 of the Backlane and then YEAH!! Freenas loaded the drives as 4TB and 6g. After that I played around updating BIOS FRU BMC because of the Fans running crazy till this smell came up and the Powercord of the distributer melted... OK I had to much running over it - at least this 10 Fans wich sounded like they want to move the Server like a Hovercraft... After some Repair and getting Power from a different Circuit I found this: I'm not sure but I think the burnt one was connected to the middle port of the Backplane and the HBA now has a fixed Cable! This is how I found it cause I wanted to rearrange... I really thought the Backplane is a dumb thing So if someone could help me out understanding this??? Is there some strange Power coming from the Enclosure Controller to the former Expander ports?? Do I have to configure, solder, jumper or kick it out of the Window let that Hover fly??? I am limited with this:
