I'm curious here, and definitely will admit to not being fully versed in
this, but, at work, all our production servers are currently running
Solaris (am working on getting some of the switch to FreeBSD) and my
preference, to date, has been to use software RAID (Sun's DiskSuite).
Main reason, the ability to transparently add drive space to a system. I
can add, configure and grow a file system without having to shut down the
server...
With hardware RAID, there is no ability to 'grow a file system'...is
there? I'm just quoting a project now where we're looking at using
Solaris+DiskSuite because of the ability to do that...and am wondering if
maybe I'm wrong with not going hardware vs software RAID...
