Web Server QoS Errors
« on: June 10, 2019, 10:45:27 PM »
These are all my vms:
appserver1、mailserver1、webserver1、infraserver1、batchserver1  in numa node 1;

appserver2、mailserver2、webserver2、infraserver2、batchserver2  in numa node 1;

appserver3、mailserver3、webserver3、infraserver3、batchserver3  in numa node 1;

appserver4、mailserver4、webserver4、infraserver4、batchserver4  in numa node 2;

appserver5、mailserver5、webserver5、infraserver5、batchserver5  in numa node 2;

appserver6、mailserver6、webserver6、infraserver6、batchserver6  in numa node 2;

dbserver1、dbserver5 in numa node 0;

appserver is configurated:4 core、8GB ram;

dbserver is configurated:12 core、28GB ram;

infraserver is configurated:1 core、2GB ram;

webserver is configurated:2 core、12GB ram;

mailserver is configurated:1 core、1GB ram;

batchserver is configurated:2 core、1GB ram;

All vm use Mellanox 25Gb vf;

When I ran 4 tiles, I can have a good result; but when I run 6 tiles, the QoS of webserver4,webserver5,webserver6 cannot pass:
Run 1
Tile 4
Web Server Errors:
Iteration 1 failed 95% TIME GOOD QoS. Achieved: 90.1%
Iteration 1 failed 99% TIME TOLERABLE QoS. Achieved: 96.9%
Tile 5
Web Server Errors:
Iteration 1 failed 95% TIME GOOD QoS. Achieved: 90.4%
Iteration 1 failed 99% TIME TOLERABLE QoS. Achieved: 97.1%
Tile 6
Web Server Errors:
Iteration 1 failed 95% TIME GOOD QoS. Achieved: 89.8%
Iteration 1 failed 99% TIME TOLERABLE QoS. Achieved: 97.0%

I am confused about it.

Hi Zoubotao,

This seems more like resourcing/tuning issue. Since you've already got 4T passing, I would recommend u to first try 5T and monitor resource utilization.

Also, you can refer to latest published results on how to tune your testbed to support more tiles.

Thanks,
Ramya
