I have no problems using AHCI on our Supermicro SuperServer 5015M-T+ systems, which are Intel ICH7-based, and with disks ranging up to 500GB. There are no disk geometry issues I encounter. Here's an example of one of the heavily-loaded boxes. The boot/OS disk is ad4. atapci1: <Intel AHCI controller> port 0x30e8-0x30ef,0x30dc-0x30df,0x30e0-0x30e7,0x30d8-0x30db,0x30b0-0x30bf mem 0xe8600400-0xe86007ff irq 19 at device 31.2 on pci0 atapci1: [ITHREAD] atapci1: AHCI Version 01.10 controller with 4 ports detected ata2: <ATA channel 0> on atapci1 ata2: [ITHREAD] ata3: <ATA channel 1> on atapci1 ata3: [ITHREAD] ata4: <ATA channel 2> on atapci1 ata4: [ITHREAD] ata5: <ATA channel 3> on atapci1 ata5: [ITHREAD] ad4: 190782MB <WDC WD2000JD-00HBB0 08.02D08> at ata2-master SATA150 ad6: 476940MB <WDC WD5000AAKS-00YGA0 12.01C02> at ata3-master SATA300 ad8: 476940MB <WDC WD5000AAKS-00TMA0 12.01C01> at ata4-master SATA300 ad10: 476940MB <WDC WD5000AAKS-00TMA0 12.01C01> at ata5-master SATA300 -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
