I've used HP/cciss on a couple hundred systems over the past 7 years,
can only recall 2 issues, both around a drive failing the controller
didn't force the drive off line, and there was no way to force it
off line using the command line tool, so had to go on site and physically
yank the drive. With the failing drive still in the array performance
tanked.

I've never used SATA on cciss, that could be a cause of issues.

Used several hundred 3ware controllers too, only a few issues.

My own opinion is I use proper storage arrays for storage, and only
use server-based controllers for the OS and basic stuff. And for my
VMware systems they are all boot from SAN. Will be trying boot from
SAN on CentOS 5.4 again soon, it didn't work properly on 5.2.

I feel much more comfortable with separation of storage from the
server for my important data.
