[opensuse] SATAII PCI / PCI-X Raid Controller Recommendation
Hello SuSE folkz, Could somebody please recommend SATAII PCI / PCI-X Raid controller (4 ports or more) which is NATIVELY supported in Open SuSE 10.1 or 10.2. Many thanks in advance, Alex -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

What do you hope to gain with a raid controller that you can't get from software raid? Yast makes setting up software raid as easy as falling off a log, and you can mix devices (scsi, ide, sata). Its robust and fault tolerant, and you are not dependent on somebody having drivers. -- _____________________________________ John Andersen -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

First, stay away from fake raid. (See http://linux-ata.org/faq-sata-raid.html). As you can see most Sata Raid controllers are fake raid and thus linux does not support them except in a JBOD configuration. For real hardware SATA raid: I haven't used the 3ware SATA raid controllers, but I have been very happy with their PATA raid controllers. They present a SCSI interface at the PCI level, then convert that to SATA/PATA going to the drive. Their SCSI (PATA) driver has been supported on SUSE for 3 or 4 years. (Vanilla kernel too for a long time.) I'm pretty sure their SCSI (SATA) support has been around equally as long. The above means you're using the SCSI driver subsystem when you use 3ware cards. Historically the SCSI driver subsystem has been more stable than the IDE / libata drivers in 2.6. (Rapid improvement in libata may be changing that.) FYI: There is another similar card that is also highly recommended, but I can't think of the manfacturer right now and I've never used it.

Not true! There is dmraid, which allows you to use fakeRAID setups. Philipp -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
