I wondering if the new 3Tb disks would work in this scenario;
I've tried 3 TB disks on a 32-bit CentOS 5 box, plugged into generic Intel PIIX on-board SATA ports. It seemed to work fine.
I only did it to see if it would work, so I currently have no systems deployed like that. Everything using 3 TB disks in production right now does so via a 3ware RAID controller. The big gotcha there is that only their newest controllers (9700 series) support 3 TB disks.
If they are 4k sector devices you need to be sure the partitions are aligned correctly or you will have a huge hit in write performance (although everything will still appear to be working). I don't think the tools in 5.x know how to do this automatically yet.
