1. PROMISE RAID 5 Controller, PCI32/64 bit internal Card.
2. Promise Tech.
3. SX4000 (and many others of the same type/family)
4. Great Raid/HDD controllers but little to no Linux support. Drivers for the SX4000 are only for Red Hat 9 and SuSE. Plus, binaries are only available on a floppy image. Most of the driver code is open source though.
