I want to use HP Embedded SATA RAID controller for RAID 1 (disk mirroring).
Deja vu, I just installed an HP DL where I thought I had problems with the external RAID controller, but it hadn't. In bypassing I also had to read some information about those "HP Embedded SATA RAID controllers". AFAIK, these are not hardware controllers, but "fakeRAID" and therefore everyone usually recommends *not* using their RAID functions but using the Linux software RAID directly with the SATA drives.

Indeed, the LSI logic controllers that ship with some HP workstations do not provide adequate RAID protection and as such, is recommended that you either install another RAID controller in the machine or use software RAID. The LSI Logic MegaRAID 8888ELP is pretty good, although a bit pricey. I thoroughly dislike HP's own RAID controller offerings - had more problems with them than I care to mention here.

Most onboard controllers are pretty lackluster, and those that use fake raid are obviously pretty hokey.

I hope you don't dislike HP's controllers designed for the its servers, like the P800 etc, as they are using the same chip as your preferred controller :) The e/p line of smart array controllers have been the most rock solid controllers (including my OE LSI's like the one you mention) I have ever used.

Maybe so, but I've found the P800s to be incredibly flakey. Performance wise, fine - no problems - but the p800s have failed more times than I can say. Just transporting machines with them to customers have been enough to kill the controller. A slight knock here, a slight knock there - blam. Can't say the same about the 888ELP - we've shipped several and have been absolutely rock solid.
