Re: Ceph-OSD on compute nodes?

[Sébastien Han <sebastien.han@xxxxxxxxxxxx>]

The "not recommended statement" is more a general performance concern. I believe the main problem here is the RAM consumed by the hypervisor and the RAM needed for the OSD (and good buffer cache too).

CPU load is also something to take into account.

How does the community feel about running OSDs on the same node as openstack compute? What if its only 3 sata disks? Isnt ceph-OSD a bit to CPU and ram hungry for doing such a thing and would lead little left over for vm instances? Just curious as I just saw someone in a forum that said they were going to do that and i always thought it was not recommended by ceph developers.
