验证安装和配置

验证esxi的安装和配置

1 - 在esxi上运行iperf3

使用iperf3验证网卡的速度

准备软件

在esxi6.7上准备iperf

ssh 登录 esxi 6.7, 然后执行以下命令:

mkdir /temp
cd /temp
wget http://vibsdepot.v-front.de/depot/bundles/iperf-2.0.5-1-offline_bundle.zip 
esxcli software vib install -d /temp/iperf-2.0.5-1-offline_bundle.zip  --no-sig-check

结果输出为:

Installation Result
   Message: Operation finished successfully.
   Reboot Required: false
   VIBs Installed: DAST_bootbank_iperf_2.0.5-1
   VIBs Removed: 
   VIBs Skipped: 

清理并进入目录:

rm -rf /temp
cd /opt/iperf/bin
cp iperf iperf.copy

准备网络

查看目前 esxi 的网络情况:

esxcli network ip interface ipv4 get

如果只有一个网卡(兼管理网络),输出类似:

Name  IPv4 Address  IPv4 Netmask   IPv4 Broadcast  Address Type  Gateway      DHCP DNS
----  ------------  -------------  --------------  ------------  -----------  --------
vmk0  192.168.0.58  255.255.255.0  192.168.0.255   STATIC        192.168.0.1     false

另外测试之前关闭esxi的防火墙:

esxcli network firewall set --enabled false

为了测试 hp544+ 网卡(连接为56G)在 esxi 下的性能,需要在 esxi 中取消直通,然后设置相关的网络

  • virtual switches 中添加 virtual switch, 如 “vSwitch-56G”, uplink 选择 hp544+ 网卡
  • port group 中添加新的 port group,如 “56G Network”,virtual switch 选择 “vSwitch-56G”
  • vmkernel NICs 中添加新的 VMkernel NIC,port group, 选择 “56G Network”

再次查看网络:

esxcli network ip interface ipv4 get

可以看到新加的 56g 网络的 IP 地址:

Name  IPv4 Address    IPv4 Netmask   IPv4 Broadcast   Address Type  Gateway      DHCP DNS
----  --------------  -------------  ---------------  ------------  -----------  --------
vmk0  192.168.0.28    255.255.255.0  192.168.0.255    STATIC        192.168.0.1     false
vmk1  192.168.100.28  255.255.255.0  192.168.100.255  STATIC        0.0.0.0         false

测试

作为服务器端启动:

/opt/iperf/bin/iperf.copy -s -B 192.168.100.28

作为客户端

作为客户端执行:

/opt/iperf/bin/iperf.copy -c 192.168.100.1 -t 10 -P 10

-t 表示测试的总时间长度,-P 启动多线程进行并发测试,一般 8-10 比较合适。

或者增加参数, -i 表示每隔多长时间打印一次测试结果,避免长时间等待(默认需要等测试时间 -t 结束才显示结果), -f g 表示用 Gbits 来显示带宽:

/opt/iperf/bin/iperf.copy -c 192.168.100.1 -t 10 -i 2 -f g -P 10

测试结果

场景1

  • 服务器端是直通 + ubuntu server:之前测试 56g eth 模式下测速打开 48G

  • 客户端为 esxi 6.7, 自带驱动,不直通,不开启

  • 测试带宽为: 32G左右

  • cpu使用率有点高,大概20%-30%

结果:和正常的48G相比,只有 2/3 的性能,估计是 rdma 没有开启的原因。

2 - 在esxi上运行iperf3

使用iperf3验证网卡的速度

准备软件

在esxi7上准备iperf3

esxi 7 自带 iperf3,位于 /usr/lib/vmware/vsan/bin/iperf3,使用时注意先执行以下命令:

cp /usr/lib/vmware/vsan/bin/iperf3 /usr/lib/vmware/vsan/bin/iperf3.copy

复制一份作为服务器端使用,否则直接通过 iperf3 运行服务器端,会报错:

/usr/lib/vmware/vsan/bin/iperf3 -s -B 192.168.0.40
iperf3: error - unable to start listener for connections: Operation not permitted
iperf3: exiting

关于这一点请参考:

另外测试之前关闭esxi的防火墙:

esxcli network firewall set --enabled false

在windows10上准备iperf3

从 iperf 官方网站上下载 iperf3:

iPerf - Download iPerf3 and original iPerf pre-compiled binaries

准备网络

网络连接概述

两台机器之间一共有三组网络连接:

  1. 千兆网络:esxi主机和开发机器之间通过千兆交换机连接,都是千兆有线网卡, ip地址设置为 192.168.0.10 和 192.168.0.40
  2. 五千兆高速网络:esxi主机上插一块 aqn-108 五千兆网卡(支持windows、linux和exsi),开发机器主板自带一块 aqn-111c 五千兆网卡(支持windows、linux,不支持黑苹果),通过网线直连,ip地址设置为 10.0.0.10 和 10.0.0.40
  3. 40G超高速网络:esxi主机上插一块 hp 544+ 40G网卡(支持windows、linux,exsi不确定),开发机器同样插一块 hp 544+ 40G网卡(支持windows、linux,黑苹果不确定),通过40G QSFP网线直连,ip地址设置为 192.168.1.10 和 192.168.1.40

esxi网络设置

5G网络设置

首先确保5G物理网卡已经识别,链路速度为5000Mbps,全双工。

开始创建5g网络的虚拟交换机,上行链路选择上面的5g网卡:

再添加5g的端口组,虚拟交换机选择前面创建的5g交换机:

最后在vmkernel网卡中添加一个vmkernel网卡:

ip地址的设置为:

通过 -P 参数指定多线程,可以使用更大的带宽,实测下来:

  • 单线程带宽2.2g
  • 两个线程带宽3.5g
  • 三个线程带宽3.3g
  • 四个线程带宽4.7g
  • 再往上加线程带宽还是4.7g
