Disable Intel Data Direct I/O (DDIO) in R740
I am wondering how to disable Intel Data Direct I/O (DDIO) in a R740 machine. The purpose of doing so is to make remote persistent memory access more efficient by using the Appliance Remote Replication Method

If you want to turn off the DDIO function, you need to turn off the VT function. This function cannot be turned on or off separately, which is related to the VT function.
