<br>
I'm planning for a HA ONED setup, i.e. HA "Frontend"<br>
(oned/mm_sched/onecctd), sunstone (Load-Balanced) and hosts. Initially I was planning to<br>
use hardware for the different components, something along the lines of:<br>
<br>
sunstone sunstone<br>
| |<br>
|------------- LB --------------<br>
| |<br>
| |<br>
| |<br>
| |<br>
oned oned<br>
| |<br>
|------------- HA --------------<br>
| (pacemaker / corosync) |<br>
| |<br>
| |<br>
host1 ------ host2 ------- host3 ------- host4<br>
<br>
With hosts, oned en sunstone each on seperate dedicated physical boxes. That's<br>
quite a bit of hardware doing mostly "nothing". Especially if you setup<br>
several independant clouds like this. Instead of using dedicated<br>
physical hardware, a setup consisting of VM's running on top of (two of) the hosts<br>
might be a more efficient possibility. Do you have any experience with such a<br>
setup? Do you see any big drawbacks in using VM's instead of hardware?<br>
Do you want to share your HA setup design considerations with me?<br>
<br>
Thanks,<br>
<br>
Gr. Stefan<br>
