FAS8200 IOPS Calculation for Flashpool Aggregate

[PunitWaghela]

Hi Everyone,

I have FAS8200 in which I have created the aggregate with 22 NL-SAS disks (Capacity tier) and 8 SSD disks (Performance tier). Please find the below disk details.

Now, I want to calculate that How much maximum IOPS I can get from this particular aggregate? How can I calculate or get the maximum IOPS details?

Hi there,

I think I answered this for you on Discord as well - this article summarises it well:

https://kb.netapp.com/onprem/ontap/hardware/Is_it_possible_to_get_each_aggregates_max_theorical_iops_and_bandwidth

Is it possible to get each aggregate's max theorical iops and bandwidth?

• No
