Das ist ein echter RAID-Kontroller.

Der tut nur so: http://linuxmafia.com/faq/Hardware/sata.html (nach
PDC20621 suchen):
,----
| Promise FastTrak SATA150, SATA150 TX2, SATA150 TX2plus, SATA150
| TX4, SATA150 SX4, SX4-M, SATA378, and Ultra 618 series PCI cards (e.g.,
| PDC20621, PDC20275, PDC20618, PDC20318, PDC20319, PDC20375, PDC20378,
| and PDC20376 chips) PCI cards — fakeraid, mitigated by the fact that the
| Promise PDC20621 ASIC chip (on SX4, SX4-M, and TX4, but not TX2)
| functions as a "RAID accelerator" — XOR engine and memory, leaving RAID
| logic to the host CPU — but libata doesn't support that functionality at
| this time (2005-11). libata's "sata_promise" driver (for tx2/tx4,
| production quality driver) or "sata_sx4" (for sx4, beta quality driver)
| provides support a/o 2004-02-25 (included in kernel 2.6.x). Cache memory
| add-on hardware module is available for some models (OEM versions only,
| though, not retail). Proprietary fakeraid "ft" driver (ataraid?) is
| available, as are instructions. An now-unmaintained 2003-02 i386 binary
| driver (often claimed in error to be open source; people being fooled by
| its source-code wrapper) is also available.
