cosbench 压测RGW生产环境

 

 

配置信息:

使用  2个万兆网卡的RGW主机,并用OSPF做高可用和负载均衡。  Ceph OSD集群 有21Node (万兆网卡+ 12个4T SATA机械硬盘)

测试VM配置:

使用在使用VXLAN协议构建的VPC网络内的8个4核8G的VM作为cosbench driver。 使用 128个cosbench work同时执行测试,文件块大小(4M-10M)。

测试场景和结果:  

 

  ratio    throughput ratio    throughput ratio   throughput ratio   throughput        
read  80%    2.04GB/s 20%    268.98 MB/s 99%    2.34GB/s 1%    8.8MB/s        
write 20%   511.94MB/s 80%   919.69MB/s 1%    20.62MB/s 99%    967.05MB/s        

结论: RGW读能跑满2个RGW主机的万兆网卡,RGW写1GB左右,达到RGW集群顺序写上限(增加RGW主机或在主机上部署多个RGW进程或许对提升写有帮助)。
