Hi,
I am a newbee with HPE and I apologize if I have some strange questions.
I got a refurbished DL360 G9 that I am setting up with Centos 7.5. Currently it is running, but I am a bit disapointed when it comes to disk IO performance.
The server consist of the following components
- 2 x E5-2640 v4
- 64GB HPE Ram
- Dynamic Smart Array B140i Controller
- 3 x Samsung 860 EVO 2TB SSDs
The SSDs are currently in RAID0 and I get the folowing speeds with
dd if=/dev/zero of=/tmp/test.img bs=1G count=1 conv=fdatasync
1073741824 bytes (1,1 GB) copied, 3,38732 s, 317 MB/s
How can I improve disk IO performace. Would a P440ar improve the performance? Should I bypass the controller and let the OS take care of the disks? Any sugestions?
