Or use dumb LSI SAS controllers (sas3442e-r with IT firmware loaded,
$200) and port expander based chassis that allow considerable
flexibility regarding md RAID and number of SAS/SATA drives attached.
The only current caveat that is being worked on, is that use of
smartmontools causes drives to disconnect.
