If you plan to scale up in the future you could consider the following config to start with:
Pool size=2 3 x servers with OS+journal on 1 ssd, 3 journal ssds, 4 x 900 gb data disks. It will get you 5+ TB capacity and you will be able to increase pool size to 3 at some point in time. > The idea is to start with 3 nodes and scale them in the future. I am > aware that a server failure can be 33% less performance, but if the > whole pool performance is good enough with 3 replicas spread over 3 > nodes, maybe it could coupe with that. > > The biggest cost here is the racks and servers, instead of the disks, > and I prefer start with 3 high density servers and scale up them > progressively. > > Do you think that this cannot good enough for production? _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
