Moin,
We use in our Enviroment three ssd drives with four TB space in a Raid
5 on a adaptec contrioller and use on the ovirt installation the jbod
on the drive which the Adaptec Controller provide. If we have three
Servers in place we use the same config but each volume will be
replicate to the other servers.
Next year we plan to use a Raid 10 with four drives and the rest will
be the same.
I think the speed will not be the best one but für the data we have
enough redundancy im place.

For SSDs , I would use each ssd as a single brick.
Don't forget to align the LVM/XFS in case you are not using Gluster's
Ansible /which oVirt also uses for deployment/ :
