How to use the new IOPS feature

The "documentation" for the new IOPS Limits is exactly two sentences long:
https://<a href="http://docs.cloudli...imits.html</a>
Im looking for how to properly configure this new setting. For example, lets say we currently have an IO limit of 4MBps (thus a setting of 4096, since its in KB)... what is a reasonable IOPS setting?

I found one website that suggests that a good value in this scenario would be 1024 (since each io is 4KB x 1024 IOPS = 4096 KBps)
https://<a href="http://wiki.mikejun...IOPS_Limit</a>
Unfortunately, when trying to set IOPS to 1024, the customer sees something VERY strange in cPanel:

Thus... my question... how do we use this feature properly?

We have found this issue is happening under some circumstances. So far we are not sure why is this happening, however was able to reproduce it on a test servers (just with much lower scale).

My guess is that IOPS is being displayed as Bytes instead of KiloBytes?

Bogdan, the question is really... how do we use the feature? There is no documentation. Is IOPS set as bytes or kilobytes? What is a realistic number to use, for whatever setting you currently have as a Disk IO limit?

Any type of information would be good. I just find it hard to believe the feature was released, but there is no documentation as to how to use it.

Sorry for not answering your question direclly in previous post.

IOPS is number of IO operations per second, how many request was done to disks by that specified user. It depends from different factors as multiple logical requests can be combined into a single I/O request to the device. In most cases it should not be greater then 1024.

You may see the actual IOPS per disks with iostat 1 command, in tps column.

I have this same issue on my servers with it showing /1024. It is quite misleading to the customers and I have fairly often tickets about this asking if they are exceeding a limit. Maybe we could have an option to hide this in Cpanel?

[bogdan.sh]

Unfortunately there is no easy way to hide IOPS usage, they are implemented with cPanel templates. However until we provide a solid fix the workaround is to set IOPS to 0 (unlimited), as a result they will be not shown in cpanel bar at all.

Thanks.

Lately I’ve seen a lot of talk about IOPS, we need as many as possible and as such we are constantly on the look out for new ways to boost performance. No matter what kind of infrastructure we build, virtual or physical, or what ever products we use, in the end it all comes down to the end user experience
