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.

Not sure if this is the place to be asking this but I was wondering which ha=

I would like to set up a HA cluster consisting off 3 hosts to be able to run=

The engine, I can run on an other server. The hosts can be fitted with the s=

Any input you guys would like to share would be greatly appriciated.
Thanks,
