Easiest way to calculate VMware needed IOPS

I am trying to rightsize SAN and was asked the required IOPS needed for multi host VMware environment. My research seems to suggest it is not easy to gather without advanced tools. We have VeeamOne which can gather some stuff but not sure of best way to create report in v7 VeeamOne (it seems like I can run report per datastore but not all datastores at once.

How many IOPS do you need for a VM or VDI solution?

That is the question, 3 VM hosts, 2 VDI hosts. Vendor gave me script to run inside every VM for a full day to gather details. Trying to avoid manually gathering like that.

Give this a try. If it can read from your SAN, it should give you an IOPS number.

Found out that Veeam will deliver the report I am looking for as part of VeeamOne suite. Setting it up to run.

What SAN do you have?

Have you seen the VDI calculator here?

Make sure you gather your VM IOPS stats over a week per to make sure you get a full reading of the Vm high and low IOPS points for example during backing or SAN snapshot event.s

Andrew, your last link was a Java app focused on VDI. Also, I was afraid to run a Java app requesting full permissions so I skipped.

However, you've provided most of the feedback so will go ahead and award you most of the points.
