Hi cephers, Is there anyone out there using Ceph (any version) with Infiniband FDR topology network (both public and cluster), that could share some performance results? To be more specific, running something like this on a RBD volume mapped to a IB host:
# fio --rw=randread --bs=4m --numjobs=4 --iodepth=32 --runtime=22 --time_based --size=16777216k --loops=1 --ioengine=libaio --direct=1 --invalidate=1 --fsync_on_close=1 --randrepeat=1 --norandommap --group_reporting --exitall --name dev-ceph-randread-4m-4thr-libaio-32iodepth-22sec --filename=/mnt/rbdtest/test1 # fio --rw=randread --bs=1m --numjobs=4 --iodepth=32 --runtime=22 --time_based --size=16777216k --loops=1 --ioengine=libaio --direct=1 --invalidate=1 --fsync_on_close=1 --randrepeat=1 --norandommap --group_reporting --exitall --name dev-ceph-randread-1m-4thr-libaio-32iodepth-22sec --filename=/mnt/rbdtest/test2 # fio --rw=randwrite --bs=1m --numjobs=4 --iodepth=32 --runtime=22 --time_based --size=16777216k --loops=1 --ioengine=libaio --direct=1 --invalidate=1 --fsync_on_close=1 --randrepeat=1 --norandommap --group_reporting --exitall --name dev-ceph-randwrite-1m-4thr-libaio-32iodepth-22sec --filename=/mnt/rbdtest/test3 # fio --rw=randwrite --bs=4m --numjobs=4 --iodepth=32 --runtime=22 --time_based --size=16777216k --loops=1 --ioengine=libaio --direct=1 --invalidate=1 --fsync_on_close=1 --randrepeat=1 --norandommap --group_reporting --exitall --name dev-ceph-randwrite-4m-4thr-libaio-32iodepth-22sec --filename=/mnt/rbdtest/test4 will really appreciate the outputs. Thanks in advance, *German*
