WebNX.com 服务器重新benchmark

和online.net 一样,前面的测试有点不太规范,这次有机会重新测试一下

机器配置和online.net 一样, E5 1650V3, 64GB RAM, 2 X 1TB SSD ( micron 5100 enterprise SSD)

测试使用的程序是:

wget -qO- bench.sh | bash

直接测试IO,使用的是下面的commands:

dd if=/dev/zero of=test_$$ bs=64k count=16k conv=fdatasync && rm -f test_$$

直接在服务器裸机安装Centos 7,下面是测试结果:

[root@webnx ~]# hdparm -t /dev/sda

/dev/sda:
Timing buffered disk reads: 1422 MB in 3.00 seconds = 473.59 MB/sec
[root@webnx ~]# hdparm -t /dev/sdb

/dev/sdb:
Timing buffered disk reads: 1452 MB in 3.00 seconds = 483.80 MB/sec

[root@sda ~]# dd if=/dev/zero of=test_$$ bs=64k count=16k conv=fdatasync && rm -f test_$$
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB) copied, 2.75682 s, 389 MB/s

测试了几次,都在390 MB/s 左右

[root@sdb]# dd if=/dev/zero of=test_$$ bs=64k count=16k conv=fdatasync && rm -f test_$$
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB) copied, 2.75827 s, 389 MB/s

两块SSD 都是micron 的全新 1 TB SSD, 看来SSD 的速度就在400 MB/s 左右

下面看看在ESXi 6.7 上使用native drive 的表现:

Centos 7 with LVM

----------------------------------------------------------------------
CPU model : Intel(R) Xeon(R) CPU E5-1650 v3 @ 3.50GHz
Number of cores : 4
CPU frequency : 3499.997 MHz
Total size of Disk : 27.0 GB (1.3 GB Used)
Total amount of Mem : 3950 MB (165 MB Used)
Total amount of Swap : 3071 MB (0 MB Used)
System uptime : 0 days, 0 hour 6 min
Load average : 0.16, 0.10, 0.06
OS : CentOS 7.6.1810

可以看到这个这个数据非常的好,基本接近原生SSD 的表现了

下面是Centos 7 without LVM
