[CentOS] Hardware or Software RAID w/CentOS 4.4 & Gigabyte GA-81945GZME-RH motherboard
Hi all, Helping a friend setup a new machine - it will be a low volume web and mail server. He wants to set it up with 2 drives in a mirror setup. The motherboard he bought supports mirroring on the hardware level. I have heard of issues before using hardware raid on Linux systems. Which way would you recommend we go on this? Thanks for any suggestions. Dale

Never mind - turns out his motherboard doesn't support hardware raid after all :( Dale wrote:> Hi all, > > Helping a friend setup a new machine - it will be a low volume web and > mail server.

I'd prefer Linux software raid (md devices) over that, simply because you can swap either or both disks into a different machine and use it without needing a matching controller. If the controller has its own CPU I'd probably use hardware raid, although it is still a toss-up for RAID1 since simple mirrors don't add a lot of overhead. -- Les Mikesell lesmikesell at gmail.com
