I have the Promise TX2 ATA100 controller:
atapci1: <Promise TX2 ATA100 controller>
ad4: DMA limited to UDMA33, non-ATA66 cable or device
ad6: DMA limited to UDMA33, non-ATA66 cable or device
ar0: 113487MB <ATA RAID1 array> [14467/255/63] status: READY subdisks:
0 READY ad4: 114440MB <WDC WD1200JB-75CRA0> [232514/16/63] at ata2-master UDMA33
ad4: SuperSwap enclosure [FAN:4066rpm TEMP:29.0C 5.103V 11.895V]
1 READY ad6: 114440MB <WDC WD1200JB-75CRA0> [232514/16/63] at ata3-master UDMA33
ad6: SuperSwap enclosure [FAN:3924rpm TEMP:31.0C 5.049V 11.834V]
And it works great. Because of Soren's ATA code, you are able to
use atacontrol:
[bob@dakota] ~>sudo atacontrol status ar0
ar0: ATA RAID1 subdisks: ad4 ad6 status: READY
[bob@dakota] ~>sudo atacontrol enclosure 3 0
fan RPM: 4166 temp: 31.0 5V: 5.05 12V: 11.83
[bob@dakota] ~>sudo atacontrol enclosure 2 0
fan RPM: 4166 temp: 31.0 5V: 5.05 12V: 11.83
I have the SuperSwap enclosures which allow me to hot swap the drives.
I do beleve that it will support the 160G drives.
