Adding a host based adapter card to a scalar server

Hello.

I have already talked to support but they cannot assist.

We purchased a new scalar server , basically this machine - SYS-421GE-TNRT | 4U | SuperServer | Products | Supermicro

I want to add a Fiber Channel host adapter card to attach a direct attached storage to this server however super micro does not list any supported card on their site under the AOC (add on cards) section. What are my options ? Have anyone done this.

I am sure most PCI cards will work however the Lambda support engineer says adding an unsupported card can “brick” the system. Seems extreme!

thank you
