Hi community,
For those of you who are interested, I performed several benchmarks of
RADOS and RBD on different types of hardware and use case.

do :). Only the commodity cluster remains
@Mark Nelson: 2) Which bench? The RADOS one?
3) Sorry the RAID controller doesn't support JBOD...
5) I still have the commodity cluster, I'll perform some little rados benchmarks

Nice!
Minor nit: sudo echo 3 | tee /proc/sys/vm/drop_caches sudo sync
you probably want say

My two cents - on ultrafast journal(tmpfs) it means which tcp
congestion control algorithm you using. For default CUBIC delays
aggregated sixteen-osd writing speed is about 450MBps, but for DCTCP
it raising up
