I’m setting up a new iSCSI LUN / volume and am wondering what the recommended sector size is.

 

The setup wizard recommends 8KB for vmware.

 

I’ve read that QCOW2 uses 64KB blocks? Does this mean I use 64KB on the iscsi LUN? Sorry if this is a stupid question.


Yes, qcow2 uses 64K, but I'm unsure if that's optimal in any way to the underlying disks. 
I doubt it makes a noticeable difference.
