@fallingwax FWIW, I just checked at the H330 is $155 more than the S130. For a moment I thought they removed everything but the S130, but you need to select the hot plug drive trays before the H330 is an option. I know it was there because I purchased a R330 in July and linux is installed on that box right now, so know I didn’t pick a S130. But anyway, I hope you are able to turn on that option in the firmware. It looks like the S130 is using the intel software raid controllers, so you may have some luck with madm.
