Disk or partition in storage-engine device configuration - 2 devices and 4 partitions each

[malidipak1]

Continuing the discussion from Disk or partition in storage-engine device configuration:

@Albot

if you want to use partitions, you want to list out all the partitions. most modern NVMe devices perform best with ~4 partitions, but ideally you want to ensure that the number of ‘devices’ does not exceed the number of CPU cores. how did you overprovision? are you sure your model of disk benefits from OP? a lot of disks dont. ideally you should test performance with ACT before/after overprovisioning to ensure you’re actually getting some gain.

Does this means the configuration in question is right, as long as it is having 2 devices and 4 partitions each for better performance?

[Albot]

I’m not sure what the question is. The recommendation probably still holds: ideally 4x partitions per nvme drive to be used as ‘storage devices’ and ideally ‘storage devices’<=CPU cores.

Hello @Albot Thank you for clarification. I got the answer from your response.

By the way, question is how should we provision the device with how much partitions and number of devices.
