As far as I know, the R210, R310 and R410 can be bought with an option to use the onboard ICH10R SATA controller (which this generation of servers finally enable in AHCI mode), and this is what we normally do - but, I don't think there's an option to have them ship with hot-swap caddies in this configuration. You can still hot swap the drives of course, as AHCI supports this, but it's a lot more awkward to do-so. The Intel Server Chassis do offer AHCI with hot-swap options if you want to go to a different server vendor, but then they have other disadvantages (last time I looked BIOS upgrades under Linux were more awkward than with Dell boxes). The only time we use hardware RAID is if the workload really needs the low-latency writes offered by battery-backed write caching.
