Hi all

I think to create a hardware raid "1" with two hard disk. I aim to use a PCI raid controller.

And now some questions :

If my controller crash will i be able to boot the system with the one hard disk plugged directly to the mobo (as a single device)?
[If i wont be able i think i have to buy two raid controllers so i can recover my data in case the controller fails]

Which raid controller are said to be the most "linux friendly"?

For compatibility you can check the [url=http://www.linuxquestions.org/hcl/index.php/cat/201]Linux Questions Hardware Compatibility list.[/ur]

If the controller dies, I do believe you would need that same type of controller to get the drives back up and running.

We always called this 'Disk Duplexing', rather than Mirroring, when you used two controllers and two drives in a single system to do RAID 1. We did this all the time when we built our Novell Netware 3.x Servers.

My personal preference for Linux RAID controllers is 3Ware, but many people find the price of their controller to be offsetting. I find the value of my data to be far greater than the cost of the controller. but I would also throw in a hot-swap disk enclosure as well, since that feature is supported by the 3Ware cards. Disk fails, pull the drive, replace it, let the system rebuild the RAID on the fly without ever taking the server down or offline..

The hot-swap disk enclosure looks very charmy.
3ware raid controllers appeal really good but the price stil is very big...

Any other raid controllers that support hot-swap??

None that are going to be cheap...
