Ceph集群网络性能测试

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

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）
