For SATA support, try to stick to the Marvell/Supermicro Card, LSI, certain Intel and Nvidia, and the Silicon Image 3112 and 3114 chipsets. The Sun HCL is invaluable here.
Note that you want ZFS to be looking directly at the disks, not at some abstraction created by hardware RAID controllers. Therefore, you may have to set the chipset bios on these to JBOD or vanilla controller mode. Blake On 9/27/07, Christopher <[EMAIL PROTECTED]> wrote: > > Hmm.. Thanks for the input.
