If you go raid software or hardware, compile support directly into the kernel. I also had to have enother disk to boot of my 3ware system. With two disks, as alvin says, go with software raid. Use hardware raid for a monster set. I've not found much appreciable difference in performance between my hardware raid sysetem and software raid. Their might be a difference but I have not noticed it. I've used software raid on a 350gig archive/backup update server, and it scales up to a monstrous load, maxing out the network card on file syncs, and raid just goes along nicely. If you use software raid, use a kernel compiled for your processor, it speeds it up a lot. Have not noticed any speed difference between module and compiled in raid support. You also MUST have some sort of notification if a disk dies. I reccomend you have a spare disk installed in the system as a hot spare, it will dynamically add if a disk dies. I've had stories of raid disks dieing and no-one noticed for month's until another disk died, destroying the volume.
Assume when setting up raid that you'll accidentally wipe your data. I've done so on non-production systems numerous times. -- --Luke CS Sysadmin, Montana State University-Bozeman -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
