IOP calculation ( disk and node type )

Question

for 'classical storage', potential IOP limits tend to be something like Drive type Maximum recommended IOPS per driveSAS Flash (all types) 20,000SAS 15K 350SAS 10K 250NL-SAS 150   with RAID type co-efficient. For Isilon the above does not apply as node type needs to be taken into account. So how do I calculate the max IOP capability of an isilon array. Presumably its also complicated by directories being pinned to different tiers, ie if I have  multiple F* nodes and H* nodes and pinned directory x to H* nodes, then theoretical IOP capability of F* nodes is irrelevant other than saying directories pinned to F* nodes do not consume H* nodes theoretical IOPs ?

Hi,

Thanks for your question about IOP calculations. I think your calculation should give a good idea of what the max IOPS are. Is this an existing configuration or one being designed still? Are you having performance issues? This might help if you are https://dell.to/37kossM

Let us know if you have any additional questions.
