ARM服务器优化指导

  • BIOS

请按下图进行配置

  • 操作系统

请按如下方式修改/etc/sysctl.conf配置文件修改内核参数

net.ipv4.tcp_keepalive_time=600
net.ipv4.tcp_keepalive_probes=3
kernel.core_uses_pid=1

调优守护程序使用Throughput-performance配置文件:

[...]$ tuned-adm profile throughput-performance 

调优启动参数,将如下配置加入内核启动参数:

iommu.passthrough=1
  • 调优硬盘/SSD

请按如下方式格式化分区,其中nvme0n1p1为测试机上NVMe盘名,请替换为本机NVMe盘名:

– mkfs.xfs -f -b size=8192 -s size=512 /dev/nvme0n1p1

将如下配置项加入内核参数以启用BFQ:

scsi_mod.use_blk_mq=1
  • 网络

请按照厂商建议安装网卡驱动程序并配置消息队列长度,以华为Hi1822网卡为例,请参考如下链接安装Hi1822智能网卡驱动:

https://support.huawei.com/enterprise/de/doc/EDOC1100063073/42928ba6/configuring-64-queues

配置消息队列为64:

./hinicconfig hinic0 -f std_sh_4x25ge_dpdk_cfg_template0.ini

请按如下方式配置IRQ:

先禁用irqbalance系统服务;随后按照如下方式进行配置(以下enp5s0/enp4s0/enp3s0仅为示例,请根据实际情况替换为本机网卡名):

四路ARM服务器单网卡:

/var/scripts/set_irq_affinity_256.sh -x all enp4s0.

四路ARM服务器双网卡:

 /var/scripts/set_irq_affinity.sh -x 16-32,48-64,80-95,112-128 enp4s0
 /var/scripts/set_irq_affinity.sh -x 146-161,176-191,208-224,240-256 enp5s0

两路ARM服务器单网卡:

/var/scripts/set_irq_affinity_128.sh -x all enp3s0

两路ARM服务器双网卡:

./set_irq_affinity.sh -x 0-63 enp3s0
./set_irq_affinity.sh -x 64-128 enp4s0

四路服务器上请按如下方式配置中断:

ethtool -C enp4s0 adaptive-rx off adaptive-tx off rx-usecs 62 tx-usecs 62

两路服务器上请按如下方式配置中断:

ethtool-C enp4s0 adaptive-rx off adaptive-tx off rx-usecs 50 tx-usecs 50

配置增大缓冲区大小以调优网卡:

ethtool -G enp4s0 rx  4096 tx 4096

修改网卡参数,服务端为on,客户端为off:

 ethtool -K $net_dev tso on/off
 ethtool -K $net_dev lro on/off
 ethtool -K $net_dev gro on/off
 ethtool -K $net_dev gso on/off

调优rc_local,其中<256/128>处请按照本机物理核心数设置:

killall -9 polkitd

service sysmonitor stop
service irqbalance stop
service rsyslog stop
service firewalld stop

echo madvise > /sys/kernel/mm/transparent_hugepage/enabled

/var/scripts/net_tune.sh enp4s0
/var/scripts/net_tune.sh enp5s0

ethtool -G enp4s0 rx  4096 tx 4096
ethtool -G enp5s0 rx  4096 tx 4096
/var/scripts/set_irq_affinity_<256/128>.sh -x all enp4s0
ethtool -C enp4s0 adaptive-rx off adaptive-tx off rx-usecs 62 tx-usecs 62
