Choosing a RAID Controller
There are quite a number of issues involved in determining which RAID controller to purchase. Chapter 2 covered basic hardware considerations and should help you differentiate between some of the available controllers. Chapter 2 can also help you choose between purchasing a SCSI or ATA controller, which is the first step in selecting a RAID controller.
I would like to point out that although hardware RAID controllers have traditionally been SCSI-only, the demand for inexpensive and consumer-grade solutions has prompted many vendors to include ATA controllers in their product lines. There are even a few companies that specialize solely in ATA RAID controllers. While many vendors now produce ATA controllers, many of them are low-quality and geared toward consumer desktop systems, not servers. One reason for this trend is the increasing omnipresence of ATA RAID on desktop motherboards. This makes it convenient for ATA RAID chipset manufacturers to build RAID cards to supplement their product lines.
However, not all ATA RAID controllers are created equal. There are also some vendors that specialize in high-end controllers that many organizations are now using to create terabyte storage systems at costs much lower than SCSI solutions, and with comparable performance. If you do choose ATA, I urge you to investigate thoroughly the solution you are considering, so that you don’t end up with commodity hardware in a server. Some users even purchase ATA RAID controllers ...
