Re: [Xen-users] SW RAID powered Xen node - knowledgeable feedback much n
Adding HW raid would mean an 60% price increase which would lead to 60%
more VEs on the node. Would the 60% increase in VEs count but with HW RAID
be preferable over the SW RAID with less VEs?
Why would adding hardware raid result in a 60% increase in guests? HW
RAID won't necessarily perform any better than SW RAID -- particularly
depending on your workload -- so I wouldn't count on being able to load
up more i/o. I think Linux's software RAID is great, I've used it for
years, I've done things like mirror a local SATA disk to a remote iSCSI
disk for better cross-box redundancy, I've booted from it, run VMs from
it, etc., but I would still almost always prefer hardware raid as long
as we're talking about a decent (LSI, Mylex, Intel, Adaptec) controller.
