For the x4500, there is a marvell mv_sata driver that should be used.
It should be downloadable from the x4500 downloads page, sorry I don't
have the specific link handy:

Recently I have also been doing some linux work with the x4500 and I

using the sata_mv driver (v0.81). The driver will properly detect

the
driver needs some further development work to actually perform
well. I see
only 30 MB/s write rates to a single disk using a simple streaming
dd test.
Much of this bad performance may simply be due to the fact that the
driver
can not enable the disk write-back cache forcing you to use write-
thru mode.
So currently the bottom line is linux will work on the x4500. But
to get it
working well someone is going to need to invest some development
effort to
improve the linux driver.
Good luck,

There was some discussion about the driver/module for the sata
controlers in the thumper (x4500) in the linux kernel.
My question is if we bought one of these, would the CFS kernel have
everything needed to use the thumper in a safe way.
Thank You.
