Subject Re: [DISCUSS] IOPS/GB and Highest Min and Max IOPS for disk offering
Date Fri, 28 Jul 2017 12:40:07 GMT
Yes Wido, it is exactly like you said. The more space you use the more IOPS
are allocated to you. For managed storage like SolidFire, where you
guarantee IOPS performance, we have to set it for each volume on the
backend hence you need some kind of ratio to calculate the appropriate IOPS.

Thanks,
