Hello
I already ran the Exchange 2016 jetstress but i have the below result compared with Exchange calc so i want to know what is your recommendation cause i see the Exchange clac request more IOPS as recommended
as per the exch calc the iops required per DB is 14 but on jetstress report it is shown average 8 or 9 per DB
please i want to clairfy this point and confirm my understandig
The jet test has been done on 22 DBs .

Hi,
To my understanding, jetstress simulates how the physically deployed storage and server infrastructure will behave if you install Exchange on this server.
Although passing the test means Exchange server can work fine on this server,you may not get the best performance.
While,Exchange Calculator provides preferred resource requirements.
It is recommended to follow its suggestions.

So as the above snapshots :
IO database Reads/sec+ IO database Write sec ( out put from jetstress) > Total database required IOPS ( output from exchange calculater)
what is it mean?
what are your recommendation in this case?

Hi,
According to the snapshots,IOPS result from jetstress（around 9）should be less than the result from Exchange Calculator（14）.
As I mentioned above, jetstress simulates how the physically deployed storage and server infrastructure will behave if you install Exchange on this server.
Following screenshot from the jetstress guide also mentioned it:
The storage design should be based on the calculator,so it is recommended to follow the Exchange Calculator's result.
