mini sas hd Asrock M.2 to U.2 mini SAS Hd adapter and SAS HDD

[ElkossComb]

Hello guys

I was thinking of building my new NAS setup. I find a nice case in 2u format with 12 trays in front for my rack, I already have a recent motherboard with a Xeon on it and a M.2 port 

As the HDD backlane of my case offer only a Mini sas HD connexion, I was thinking about pluging an M.2 to U.2 adapter (which is specified as Mini SAS HD standard port by the manufacturer)

I want to put FreeNas on the system, so buying an expensive Raid controller with SAS embeded port is not in my mind since it's expensive, and  not recommended for Freenas OS.

 

Do you think this connexion will work / will be suitable? If not, have you a smart solution to my connexion issue

 

I don't have any information about compatibility, just the Mini SAS mention on this adapter! (https://www.asrock.com/mb/spec/card.fr.asp?Model=U.2 Kit)

 

Thanks in advance
