一.测试Ceph集群节点之间的网络性能
在ceph01节点上运行：
[root@openstack01 ~]# iperf3 -s -p 6900
-----------------------------------------------------------
Server listening on 6900
-----------------------------------------------------------
在ceph02节点上运行：
[root@openstack02 ~]# iperf3 -c openstack01 -p 6900
Connecting to host openstack01, port 6900
[ 4] local 192.168.30.102 port 50586 connected to 192.168.30.101 port 6900

iperf Done.
- 结果：可以查看两节点之间的带宽大约在2.18Gbits/s（260MBytes/s 在1/8左右）
