Thanks to all who replied.

Please forgive my ignorance in the subject, but are we talking serial
ATA (Escalade 8506) or parallel ATA (Escalade 7506) ? I've found the
support for these 3Ware devices in the kernel (3W_XXXX_RAID) but it
isn't exactly clear which of these the support is for.

Thanks again,

Mark
