Hi Todd, thanks for the reply! I am afraid this is a very controlled environment - ie - I don't have physical access to the server; and the physical config is not in my control. if this does not work as it stands, then I simply use a different host / rent a different config from the hosting provider. As such - I don't think I can do the test process you recommend. Alas.

I did only now (doh) read the HCL and confirm that the LSI-9271-4i does not appear to be specifically listed as supported. So out of the gate I am guessing this might be a baseline problem.

My plan-B Scenario I think I can try, possibly, even though it sounds bit insane.

-- install Proxmox (KVM Based virtual machine hosting virtualization environment) on the bare metal
-- install Open-E as a VM inside Proxmox / as a KVM Based VM / using standard Linux VirtIO HDD and NIC device driver config.
-- I am guessing? (hoping?!) that Open-E will have good support for linux VirtIO devices and thus it will allow me to work around this hardware limitation.

It also gives me the added benefit, I can run a BCache SSD cache layer on my datastore that holds the VM image for the OpenE VM / and possibly get better performance than I might otherwise have managed with running Open-E directly on the bare metal. :-)

I can followup to this thread a bit later (next few days) in case I have any further progress on this.

Thanks for your help!
