Well.. using mdraid means you're probably using regular SAS HBA, and not a RAID adapter..
The chassis/backplane often offers SES2 management chip.. which is usually controller by the (hardware) RAID adapter.

In the case of regular SAS HBA and software-raid, what software are you planning to use to control 
the (failure) LEDs of the backplane through SES?

I'm not aware of any generic software for Linux/mdadm that can control SES backplanes automatically..
