I am looking into building my own server running RedHat Linux 7.2 and Plesk 2.5 for colocation purposes. I am interested in adding support for RAID-1 mirroring with a controller card. I'd rather do it with hardware since it's really just as simple as adding the card, making sure Linux see's my RAID card (via the driver) and plugging in the hard drives. No other configuation would be neccessary.
However, I've never used a RAID-1 controller card on Linux before.
* How do I know if one drive has failed in this type of configuration?
* Is there some kind of software that comes with the controller card that will allow me to run status checks on the drives?
* And lastly, any recommendations on choice of hardware or how to implement a RAID-1 configuration on a RedHat Linux system?
