Question on nimble performance policy for ESX and block size tuning

It my understanding from best practice doc(bpg_nimble_storage_vmware_vsphere5.pdf) that any LUN which will contain VMFS datastores should be set to use the ESX performance policy.

 

It is also my understanding that this policy uses a 4k block size on nimble.

 

My question is in regards to the block alignment document: https://connect.nimblestorage.com/docs/DOC-1185.  Does the table on page 3/4 also apply to VMDKs on VMFS volumes or does this only apply to volumes directly mounted using MS iSCSI initiator, etc?  If it does apply to VMFS should there be a column referencing VMware block size of 1MB(or 8k sub allocation) blocks, etc and that taken into account when discussing?

 

 

 

Thanks
