Is there any SAS board supported? 

I have checked supported HW database and haven't seen any SAS board support. 

In our previous system deliveries we used IDE/SATA SOHO RAID boxes, we tried several manufacturers, but we were several 
time disappointed with the results/reliability.

It seems to me that there is a better choice of SAS RAID units, but to be able to use them SAS card would be needed in 
computer.

Or any other idea how to deliver RAID functionality?

Thanks, PKY
