Hi all, We're setting up radosgw against a large 8/3 EC pool (across 24 nodes) with a modest 4 node cache tier in front (those 4 nodes each have 20x 10k SAS drives and 4x Intel DC S3700 journals). With the cache tiering we're not sure what the best setup is for all the various peripheral rgw pools other than the main .rgw.buckets. Should these also be EC backed and cached, or (I guess more likely) should they be x3 replicated pools, in which case should they be rooted on the cache tier nodes or the main data nodes?
Our initial inkling is to put them on the data nodes as given the tiering scenario these drives should on-average not be very busy compared to the cache. -- Cheers, ~Blairo _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
