--Apple-Mail-FF4BAD67-2D6B-4D37-B4DF-9283D336B1AF Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hello Andrei, Thank you very much for sharing info on your hardware setup. Very informativ= e. At this moment I have my ovirt engine on our vmware environment which is fin= e for good backup and restore. I have 4 nodes running now all different in make and model with local storag= e and it works but lacks performance a bit. But I can get my hands on some old dell=E2=80=99s R415 with 96 Gb of ram and= 2 quadcores and 6 x 1 Gb nic=E2=80=99s. They all come with 2 x 146 Gb 15000= rpm=E2=80=99s harddisks. This isn=E2=80=99t bad but I will add more RAM for= starters. Also I would like to have some good redundant storage for this to= o and the servers have limited space to add that. Hopefully others will also share there setups and expirience like you did. Kind regards.
