Re: [Iometer-user] Limit IOpS

[Sascha E. <fe...@do...>]

Hello,

thanks, you are right, fio could do the trick. My problem is, that I 
need to do it from serveral machines in parallel. I think I did not 
mention this. Perhaps I will try to do it with fio stareted 
synchronously by any kind of script.

Therefore I want iometer to generate (about) 5000 IOPS (later about 10000, 20000, up to some hundred thousands). Is this possible using iometer? At the moment I do not see a way to solve this. Does anybody know any other tool solving this issue?
