[ovirt-users] Which hardware are you using for oVirt

[Andy Michielsen]

Hello Andrei,

Thank you very much for sharing info on your hardware setup. Very informative.

At this moment I have my ovirt engine on our vmware environment which is fine for good backup and restore.

I have 4 nodes running now all different in make and model with local storage and it works but lacks performance a bit.

But I can get my hands on some old dell’s R415 with 96 Gb of ram and 2 quadcores and 6 x 1 Gb nic’s. They all come with 2 x 146 Gb 15000 rpm’s harddisks. This isn’t bad but I will add more RAM for starters. Also I would like to have some good redundant storage for this too and the servers have limited space to add that.

Hopefully others will also share there setups and expirience like you did.

Kind regards.
