There is no need for "SATA technology support". Its an affair between device
and controller. FreeBSD-STABLE knows a few controller chips which are used
with the SATA interface. Also a lot of manufacturers provide suitable
drivers. That should be enough.
I already used a RAID1 solution with two SATA hard disks and FreeBSD 4.5(!)
without any additional drivers, that means with FreeBSD's built-in drivers
without explicit SATA support. It worked fine.

The only controller I discovered on Dell's homepage is called "Adaptec CERC
SATA1.5/6ch" or simply "CERC SATA RAID". So I assume that this is the only
SATA controller which is offered by Dell. The string "CERC SATA RAID 2"
comes only up with FreeBSD, so I guess it's an erratum and they mean the
same controller. I think in this case the controller will work with aac(4)
