在VMware ESXi上对三星PCIe 4.0 NVMe SSD 980 PRO硬盘进行直通DirectPath和虚拟化Virtualization的读写测试

在VMware ESXi上对三星PCIe 4.0 NVMe SSD 980 PRO硬盘进行直通DirectPath和虚拟化Virtualization的读写测试
存储虚拟化后，读性能损失约21.5%，写性能损失约18.4%

Read and Write Tests of Samsung PCIe 4.0 NVMe SSD 980 PRO Hard Drive with DirectPath and Virtualization on VMware ESXi

物理服务器NF5280M5
硬盘PCIEx4转NMVe
虚拟化软件ESXi 7.03
虚拟机配置8核心 16G内存 120G系统盘
操作系统CentOS7.9
数据盘三星 PCIe 4.0 NVMe SSD 980 PRO
测试软件fio

1、软件安装

yum -y install epel-release
yum -y install fio

2、挂载数据目录

sudo vgcreate lvmgroup /dev/vdb
sudo lvcreate -l 100%FREE -n data lvmgroup
sudo mkfs.xfs /dev/lvmgroup/data
sudo mkdir /data
sudo echo "/dev/lvmgroup/data /data xfs defaults 0 0" >>/etc/fstab
sudo mount -av

3、编写 fio 测试配置文件：创建一个用于 fio 测试的配置文件。您可以使用文本编辑器创建一个新文件，例如 fio_test_config.fio

[global]
ioengine=libaio
direct=1
thread=1
rw=randrw
bs=4k
numjobs=4
size=32G
runtime=300
group_reporting
 
[randwrite]
 
[global]：这部分指定了全局配置，适用于所有作业。
ioengine=libaio：指定I/O引擎为libaio，表示使用异步I/O。
direct=1：启用直接I/O，绕过操作系统的文件系统缓存。
thread=1：每个作业使用一个线程。
rw=randrw：读写模式为随机读写。
bs=4k：块大小为4KB。
numjobs=4：作业数量为4，表示并发的作业数。
size=32G：每个作业的测试文件大小为32GB。
runtime=300：测试运行时间为300秒。
group_reporting：指定所有线程的统计信息应汇总在一起报告。
