最近到了一批`HPE DL560 G9`的机器,默认带的是[P440ar](https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-c04496202)的卡。但是目前我们都是用的ZFS,所以一般来说我们都会把卡刷成`IT Mode`直通给系统。 | ||
|
||
戴尔的卡已经有[很成熟的教程](https://fohdeesha.com/docs/index.html)了,但是HP似乎都没有,目前可以选择的方案看了一圈只有 | ||
|
||
- HBA Mode,他们的卡自带了这个模式 | ||
- RAID 0 for each physical drive,我没想到的是他们界面直接就有这个选项,看来很多这样的需求 | ||
|
||
但是继续找了一下并没有看到有关于更多ZFS的评测,所以这里就记录一下目前收集到的信息 | ||
|
||
## 规格 | ||
|
||
### 硬盘 | ||
|
||
硬盘是`2.5 inch Seagate 1TB 7200 RPM`,具体信息: | ||
|
||
``` | ||
Status: OK | ||
Serial Number: 9XG6E9NN | ||
Model: ST910006CLAR1000 | ||
Media Type: HDD | ||
Capacity: 1000 GB | ||
Firmware Version: AS0D | ||
Encryption Status Not Encrypted | ||
``` | ||
|
||
### 控制器 | ||
|
||
控制器读缓存开启,写缓存关闭 | ||
|
||
## 测试 | ||
|
||
### 脚本 | ||
|
||
使用的是[fio](https://github.com/axboe/fio),配合脚本 | ||
|
||

|
||
### RAID 0 结果 | ||
|
||
<a :href="raid0">fio-raid0.tar.gz</a> | ||
|
||
### HBA 结果 | ||
|
||
<a :href="hba">fio-hba.tar.gz</a> | ||
|
||
## 结论 | ||
|
||
目前测试出来单盘的情况下,HBA和Raid0的结果在512K的读写下很相近,但是HBA模式表现似乎要更好一点。 | ||
|
||
所有结果都打包在上面,有需要的可以自行下载研究。如果有更多测试/模式想要测试,可以在评论区留言 | ||

<script> | ||
export default { | ||
data () { | ||
return { | ||
raid0: require("../_assets/file/p440ar-ctrl-benchmark/fio-raid0.tar.gz"), | ||
hba: require("../_assets/file/p440ar-ctrl-benchmark/fio-hba.tar.gz"), | ||
} | ||
}, | ||
} | ||
