I set up a ESXi (6.7 u3) datastore on a FreeNAS NFS share. The connection is 10GbE via a 10GbE switch. When running CrystalDiskMark to benchmark VMs' disk performance, the reads are going through each server's gigabit NIC and the writes are going through each server's 10GbE NIC. The 10GbE NICs are on a separate subnet, I mounted the NFS share using the FreeNAS server's 10GbE IP address and on the ESXi side I created a separate port group, virtual switch and vmkernel NIC for the 10GbE connection yet reads go through the server's gigabit NIC.
Any clue why this is happening and how to resolve it?
