Hi All I'm new to the list so apologies if any of my questions have come up before and been answered. Given the costs of a hardware raid solution here in South Africa (3-4 times the cost of hardware at online retailers) I've opted for a software raid configuration under Debian Linux. Where I'm hitting a snag is in determining the ideal hardware setup. The motherboard has an onboard ide controller but only two channels. I'd like to run raid 5 and have investigated costs for purchasing two new pci parallel ATA ide controllers, or one pci SATA ide controller. (I don't want one controller under via chipset and another under a different chipset - seems like things may go wrong in that situation) 1) Will one SATA ide controller suffice if I want to run four disks off it, one acting as hot spare. (yeah I know s/w raid is over partitions). I'm completely unfamiliar with SATA and don't know if you can run four masters off four SATA connections on the same SATA pci card. 2) Other option is two have two duplicate pci parallel ide controllers (leave the onboard Via chipset controller out of the equation) and run two disks per controller. Is there anything I should be aware of if I'm sticking in two pci ide controllers. Is this a suggested solution? 3) I've looked at the Promise SATA150 TX4 and the Promise Ultra133 TX2: of these two which is better. Broad question I know, but I'm a bit confused as to whether moving to SATA is even worth it just yet as the costs are considerably higher than parallel ATA. 4) Is there any other brand of SATA/Parallel pci controller card that will have few to none driver/kernel issues under Linux. Any particular brand well supported and ideal? Thanks in advance and once I have a clear idea of what I'm doing on the initial hardware setup I'll probably have some more interesting questions to ponder.
