Intel P3600 NVMe 2.5" pauses between write bursts

Hello

I am testing 2 Intel P3600 400 GB in RAID 0 as cache volumes on linux CentOS 7.

During a random write benchmark with iozone I notice frequent long pauses where NOTHING gets written to disk

Am I the only one seeing this?

Regards

ROF,

Could you try http://www.iometer.org/doc/downloads.html Iometer and see if you get the same results?

How did you set up your RAID 0 ?

What type of RAID controller are you using?

Did you try these drive individually in order to check the results?

Here is how you can use Iometer:

 

Step 1

Step 2.

Step 3.

Step 4.

Let us know the results.
