HPP, direct submission, IO Scheduler, latency sensitive threshold with NVMe over FC (NVMf)

  • 1.  HPP, direct submission, IO Scheduler, latency sensitive threshold with NVMe over FC (NVMf)

    Posted Oct 15, 2024 02:37 PM

    Can anyone clarify if direct submission is used by default, over the IO scheduler, with the HPP and NVMe over FC volumes?

    The wording in the documentation here, https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-storage/GUID-F7B60A5A-D077-4E37-8CA7-8CB912173D24.html, makes it seem that the IO scheduler is always used unless a value is defined and manually set for the latencythreshold in the cli?

    Has anyone done this to enable direct submission and recorded any performance results, or can provide any feedback?
