Hi I have finally configured a ceph cluster with 8 nodes. I have 2 MDS servers and 3 monitors and rest of 3 nodes are OSD. Each system has 2T SATA drives. I have 3 partitions created, one for root file system, another for CEPH journal and the rest of the space is for OSD. I was able to get 5.6T space from three nodes. All the machines are of same type (HP DL160 G7) with 48 of RAM and quad core dual cpu's. I am using iozone for testing the performance against NetApp filer Below is the command what I am using for iozone test /opt/iozone/bin/iozone -R -e -l i -u 1 -r 4096k -s 1024m -F /mnt/ceph- test/ceph.iozone When I see the result, the value from ceph cluster is not at all coming near to an entry level NetApp filer. I would like to know the ideal way (if there is any) for testing ceph cluster performance so that we can compare it with other file systems. If required, I can share the test results. Any suggestion greatly appreciated.
