My OSD servers have 4 network ports currently, configured as:
eth0 - lan/osd public
eth1 - unused
eth2 - osd cluster network #1
eth3 - osd cluster network #2
each server has two OSD's, one is configured on osd cluster network #1, the
other on osd cluster network #2. This avoids any messing around

Hi Gilles,
Thanks a lot for the answer, i've made a new benchmark test with
bio, i've used the following configuration for the test:
; Four threads, two query, two writers.
[global]
rw=randread
size=256m
directory=/mnt/ceph-btrfs-test
ioengine=libaio
iodepth=4
invalidate=1

You should really write anything but zeros.
I suspect that nothing is really written to disk, specially on btrfs, a

Hi to all,
I'm testing Ceph with a 4 server configuration with 300GB 15K
SAS disks used for the OSD's, the journal is included inside the OSD
partition also. And i want to know if it's possible with Ceph to
obtain a 400-700MB/sec of throughput. I've tested with XFS and BRTFS
when doing t
