NIMBLE_PSP_DIRECTED vs "iops=1"
The NIMBLE_PSP_DIRECTED SATP rule automatically created by NCM does not appear to have any PSP options set. Is "iops=1" implied with this rule or should I explicitly specify it? I'm trying to get this rule into my host profiles so that future host remediations don't back out anything that might have been set by NCM.
Thanks!

Re: NIMBLE_PSP_DIRECTED vs "iops=1"
On the other hand, I've just spotted a five year-old thread where the results of "policy=iops;iops=0" (which effectively sets the round-robin technique to least queue depth) were very encouraging. Whatever became of this?

Re: NIMBLE_PSP_DIRECTED vs "iops=1"
Looks like "iops=1" is implicit. I guess I don't need to worry about the SATP rule in my host profiles.

Re: NIMBLE_PSP_DIRECTED vs "iops=1"
I've also discovered that NCM refrains from altering Disk.FailDiskRegistration and Scsi.CompareLUNNumber unless there's a Nimble volume present. That explains why this, too, was missing from my extracted host profile.
