Hello Stanley, Thank you for your recommendations after consult with vmware support this is not about vmware configurations. By the way I found repeatedly messages on vmkernel.log "NMP device "naa.blablablablaxxxx" state in doubt; requested fast path state update", so I try to deep investigate on I/O path and found the root cause was a SAN switch. After replacement of SAN switch everything look good no ping loss anymore. Thanks, Nawa
