My question as per title.

The Nutanix sizer does not shows the capable iops of a configuration... Is there any tools available to determine or estimate the capable iops of a Nutanix configuration?

Hi @Ronnie_Lam @alberto-sesena

There are multiple factors that come into this, including whether the solutions is all flash or hybrid, and if all flash, what type of flash is used, NVMe vs SSD. Also the processor choice comes into it. It also depends on the hypervisor and on the IO workload mix.

Dear Nutanixers,

please do respond to this question. I do have the same doubt. My customer asks about the maximum number of IOPS per cluster as it is designed I mean before the implementation phase.

Thanks in advance and regards !!!!!

Hi,

You should contact your local Nutanix SE, they can give you idea what the IOPS numbers based on BoM.
Basically traditional storage vendors had created so much hype of IOPS, that this is always the first question from customer, in that case i always ask customer how much IOPS "you" need?
Predicting IOPS is not that easy as there are lots of factors involved, I had seen a enterprise customer running high end storage box generating less than 50K peak IOPS for SAP and Oracle plus 400 VMs. You can easily get 50K IOPS from Nutanix NX1065 model with three nodes.
