So I'm lazy. Or stupid. Or both. I did try to follow the instructions  
previously pointed at for how to configure RAIDframe with grub and  
xen but I messed it up somehow. And on another box I installed  
RAIDframe (w/o grub or xen) only to have it run fine, but always come  
up with dirty parity after a reboot. Haven't figured out why yet  
(suggestions?). So I'm clearly not up to speed on RAIDframe yet.

And as I'm short on time and also interested in hot-swap (this will  
be a remote box where the ability to use remote hands to swap disks  
on a running system would be really great) I'm contemplating my first  
hardware RAID ever.

The system has 4 x SATA disks and I'm looking at either

* Adaptec 2410SA (supported by aac(4))

or

* 3ware Escalade 9500S-4LP (supported by twa(4) or twe(4), although  
looking again that seems less than clear)

Any recommendations? Any concerns?

Johan
