Raid controller doesnt see expander

[dwisehart]

Hello,
My Intel RT3WB080 RAID controller says it supports port expanders, but when I plug in a CFI-B53PM 5 Port Backplane (SiI3726), the controller only reports one drive.

I have tried lots of options in the RAID BIOS pre-boot command tool and commands like -pdGetNum -a0 only find one drive. A cheapo Adaptec controller that doesn't have all of the features I need and doesn't work with more than two controllers in the motherboard at once sees all five drives just fine. Where can I go for help?

Thanks,
Daniel

Unless someone here has experience with that particular board, can you contact your vendor or Intel for support?

LOL!

That is a SAS controller, it needs a SAS expander, not Port Multiplier
the cost of SAS expander range about $280~ $350.00/ea

I had looked that up and seen that it is a SAS controller. But SAS controllers can control SATA drives, yes? So they are compatible with the drives but not the multipliers? I had no idea.

Yes, SAS controller will work with SATA drive, but it DOES NOT Support Port Multiplier (PM Ware)

To expand, it has to use SAS expander, not PM
