Hello,
On typical deployment scenarios of oVirt which is the recommended RAID technologies for
oVirt Node installation? Should I use controller based RAID or mdadm can be used instead?
Is this recommended?
I’m asking this because other vendors requires hardware RAID, even those 100% based on
CentOS, like XenServer. There’s not even a way to install it with mdadm (Software Raid).
Thanks,
V.

I use Linux software RAID under oVirt just fine. I'm not using oVirt
Node though (I just installed CentOS and then installed oVirt). Note
that I have an iSCSI SAN for VM storage - things might be different if
you are planning to use the local disks for VMs (local storage or
Gluster).

Hello Chris,
On non-node installation I can’t see any problems as you said, but due to the appliance
nature of oVirt Node I don’t know if this would be a supported scenario. Anyway you raised
a good point: local storage. I’m not needing this, perhaps someone on the list will be
using this feature.

It depends on your definition of "supported."
However this is the mode I'm using, too. ovirt on top of CentOS with
sw-raid. Haven't had any problems.
