I wonder if you should not have chosen a different product? Ceph is meant to distribute data across nodes, racks, data centers etc. For a nail use a hammer, for a screw use a screw driver. -----Original Message----- To: ceph-users@xxxxxxx Subject: *****SPAM***** layout help: need chassis local io to minimize net links Hi I have a few servers each with 6 or more disks, with a storage workload that's around 80% done entirely within each server. From a work-to-be-done perspective there's no need for 80% of the load to traverse network interfaces, the rest needs what ceph is all about. So I cooked up a set of crush maps and pools, one map/pool for each server and one map/pool for the whole. Skipping the long story, the performance remains network link speed bound and has got to change. "Chassis local" io is too slow. I even tried putting a mon within each server. I'd like to avoid having to revert to some other HA filesystem per server with ceph at the chassis layer if I can help it. Any notions that would allow 'chassis local' rbd traffic to avoid or mostly avoid leaving the box?
