hi all,

we are planning to purchse new OSD hardware, and we are wondering if for
upcoming luminous with bluestore OSDs, anything wrt the hardware
recommendations from
http://docs.ceph.com/docs/master/start/hardware-recommendations/
will be different, esp the memory/cpu part. i understand from colleagues
that the async messenger makes a big difference in memory usage (maybe
also cpu load?); but we are also interested in the "1GB of RAM per TB"
recommendation/requirement.

many thanks,

stijn
