Re: [Xen-users] Recommended partitioning for xen host

[Geoff Kirk <geoff.k@xxxxxxxxxxxxxxxxxxx>]

Hi again,

I think a lot depends only sure way to know is test it. I use Xen with 
very low end hardware (PIII's 512MB ram each) i use no raid and in some 
cases everything but the root is all on one ide device. It works fine 
for what i do which is very light weight work loads really. But sure if 
you need the disk IO performance using more than one disk or raid is 
very useful. iSCSI seems to be of interest in larger scale deployments.
