How can I get the result table?

Benchmarks SSD Benchmarks (using ACT)

Hi guys. I installed ACT 5.3 in my server and ready for run. I wanna get ACT result table like in this page’s PCIe/NVMe-Based Flash section.

How can I get the Speed(tps) and Endurance column result in my SSD? Act Github page’s sample only shows these values…

         reads                  device-reads
         %>(ms)                 %>(ms)
 slice        1      8     64        1      8     64
 -----   ------ ------ ------   ------ ------ ------
     1     1.67   0.00   0.00     1.63   0.00   0.00
     2     1.38   0.00   0.00     1.32   0.00   0.00
     3     1.80   0.14   0.00     1.56   0.08   0.00

Thank you for your help!

I think you are looking for -x.

-x - optional parameter indicating that throughputs should also be displayed: default is no

Thank you kporter! what I wanna get values are these(Speed (tps) and Endurance) columns. (please see. under the table)

Flash Device Speed (tps) >1ms >8ms >64ms Endurance ACT Source
SmartIOPS DataEngine 6.4 TB 825,000 0.30% 0.00% 0.00% 3 DWPD 3 SmartIOPS
SmartIOPS DataEngine 3.2 TB 630,000 1.5% 0.01% 0.00% 3 DWPD 3 SmartIOPS
…

Values for endurance are taken from manufacturer’s spec sheets and have not been independantly verified.

Should also probably be mentioned that the speeds posted on the SSD Certification page show writes+reads per second as TPS. the -x feature reports only reads i believe.

Thanks a lot @kporter. How about Speed(tps)? Actually I wondering about tps. How can I get tps metric value? (act test in my SSD)

And… Aerospike said These devices were tested at the specified speed with a 67% read/33% write ratio of 1.5 KB objects over 24 hours. => How can I tune that configuration in act_storage.conf?

7

These are the defaults. You can read the README on the ACT github page on how to change these parameters (writes/s reads/s record size, test time). The TPS is just the writes/s+reads/s.

8

Thank you @Albot!! That’s right… -x option only shows reads

So the Speed (tps) posted on the SSD Certification page means maximum writes/s+reads/s?

9

Yes, with the regular ACT qualifications (like no more than 5% > 1ms)

Thanks a lot @Albot

If I tested my SSD using ACT 5.3 (read-reqs-per-sec: 60000, write-reqs-per-sec: 30000 parameters were in the act_storage.conf)

In my understanding, below table (I wrote) looks good. Is there any problem?

Flash Device Speed (tps) >1ms >8ms >64ms Endurance ACT Source
my SSD x TB 90,000 2.73% 0.00% 0.00% x DWPD 5.3 my Company

Right. Exactly. 2.73% >1ms sounds like it can go faster though :wink:
