10. IDE RAID Controllers

• Tekram D690CD IDE PCI Cache Controller (with RAID level 1 Mirroring and caching)

• ARCO Inc. DupliDisk IDE disk mirroring controller

  Support for ATA, IDE, E-IDE and UDMA drive. Controllers available can be plugged into ISA and PCI slots, and directly into the IDE controller. Furthermore, 3.5-inch and 5.25-inch Bay Mount units are available that fit into the respective drive bays. More information at Arco's web site. Make sure you have at least rev 3.00 of the firmware.

• 3ware Escalade IDE RAID controllers

  3ware's 5000-series and 6000-series controllers have been supported since kernel 2.2.15. Support for the 7000-series controllers and RAID5 on the 6000-series controllers requires kernel 2.4.5 or 2.2.20 or better. Also make sure to use a recent firmware for RAID 5, since older firmware revisions (and older versions of the driver) can cause data corruption when a RAID 5 array runs degraded. 8000-series SATA cards also work fine with recent 2.4.x or 2.6.x kernels. 9000-series cards are supported with the 3w-9xxx driver (instead of the older 3w-xxxx driver).

• Adaptec ATA RAID 2400A

  4-port ATA/100 controller which supports RAID 0, RAID 1, RAID 1+0, and RAID 5. Use the dpt_i2o driver, which is included in recent 2.4.x kernels.

• Promise SuperTRAK SX6000

  6-port ATA/100 controller which supports RAID 0, RAID 1, RAID 1+0, RAID 3, and RAID 5. Use the pti_st driver or the generic i2o drivers. Be sure to set the BIOS on the card for "Other OS" instead of "Linux", and check for firmware updates.
