Re: [ovirt-users] planning ovirt for production
Hi, Thank you for you reply. Is it better than a replica beetwen two node? My plan is one server for ovirt (based on hw raid10) and two server for replication. Is better with 3 servers? Also, is 1GBe NIC will be enought for performance? I would use bonding.
