Managing RAID on Linux

Chapter 5. Hardware RAID

Today, nearly every RAID controller manufacturer supports Linux in at least one of its product lines. Furthermore, most of these vendors now provide open source drivers for their cards, although in a few cases, the drivers have been developed by philanthropic programmers. Some vendors have even ported their management applications to Linux, although none of them yet provide source code for these applications. The vendors and products discussed in this section are:

• Mylex AcceleRAID 352 (SCSI)

• Adaptec 2100S (SCSI)

• Promise FastTrak100 (ATA)

• 3ware Escalade 7500 (ATA)

• LSI Logic MegaRAID Elite 1650 (SCSI) and MegaRAID i4 (ATA)

The sections devoted to individual controllers apply generally to other models from the same vendor, since they often share the same firmware and management interfaces. I’ll point out any differences of which I’m aware. The introductory sections of this chapter will provide useful information, even if you choose a vendor that I have not covered.
