Hi all, I've read nearly whole thread, but I can't find definitive answer for my question: Can the external SFF-8088 port on HP expander card be used as uplink to the controller? (LSI 9207-8e in my case) Some say that it works, others say that it doesn't.

Thanks, of course I'll try, but it's good to know at least one working setup. Have you tested if HDDs can be connected to the "to controller" ports when using external port as uplink?

How much HDDs can you connect to one expander?
Look at the card, bottom ports are labelled as "to controller". Did you try connecting disks there?

FINALLY! Got it working!!!!!

Created a post on reddit and got a reply from user skels130
"According to my research, many, if not most, motherboards will not power a paid device without a CPU."

I bought a PCI-E Rise board, the ones people use for bitcoin mining with multiple GPUs
And it worked!


Also easy way to tell if the SAS Expander will work in your motherboard is:
Turn it on.
If LED R6 is remains Solid Green permanently then your motherboards isnt powering it up fully
If LED R6 is Solid Green for a few seconds, then goes to a continuous blink, then it's powered up properly

Linux terminal in Ubuntu still did not detect the SAS expander but did detect a Logical volume connected to it
But the Service Pack for Proliant boot USB worked and updated the SAS Expander firmware to latest, 2.10C

Also fixed the 2 drive detected issue.
Once I detected by the SPP boot USB, it then shows the drives in the Smart Storage Administrator
From there I cleared the current configuration and set each drive to a separate individual Raid 0 "Array"

Now all external 3 drives connected to the expander are being detected by the server.
now to test withxpenology.
For the record, this is what I did many years ago when I built my file server with an ITX motherboard and Perc H310 in IT mode.

Still working great 3 years later.

I never really got mine to work the way I wanted it to.

In the end I decided to just dispense with expanders, and dropped a considerably larger sum on an LSI SAS 9305-24i.

It cost a bit more, but it definitely does the trick.

It's funny though. They call it low profile, but in most low profile cases you can't use the top two ports. Not a problem for me in my 4U case though.

Hey, you sure you uploaded the right picture? All we can see is a card that's not connected to anything - doubt that "works" 3 years later. Did you want to show some sort of hook-up scheme or something?
