If there are other places to look for none biased info, please feel free to redirect me. We're running a FreeBSD shop, and 2 ccd's on our usenet-news system, but several other systems I'm searching for a stand-alone RAID. (SCSI in, SCSI out). We'll probably be wanting to run either level 3 or 5. I'm aware of the ccd stripe/mirror functionality, but I'm sort of bothered by the fact that rebuilds have to be done "ofline". I would be most gratefull if people could advise me on this topic. Some questions in my mind: What are they using? How flexible is it? What is the penalty of a crashed disk and how fast and easy is the system again rebuild. How is the RAID managed? How much did it cost?
