I'm confused about requirements for ceph services.
http://ceph.com/docs/master/start/hardware-recommendations/
"Monitors simply maintain a master copy of the cluster map, so they are
not CPU intensive"
and then in RAM section
"Metadata servers and monitors must be capable of serving their data
quickly, so they should have plenty of RAM (e.g., 1GB of RAM per daemon
instance)."
And if I understand correctly, monitors are the access points to the
cluster, so they should provide enough aggregated network output for all
connected clients based on number of OSDs in the cluster?
And another question about ceph and aws.
Is anybody built anything decent on aws using Ceph, I mean storage
itself? Or its not worth the effort since amazon might be already using
ceph-alike system on the backend.
Thanks,
