Slow throughput performance during BMR

Using Arcserve UDP Agent (Windows) › How to Perform a Bare Metal Recovery Using a Virtual Standby VM or Instant VM › Troubleshooting BMR Issues › Slow throughput performance during BMR

This problem can be caused by SATA controllers with "AHCI" enabled.

During BMR, Arcserve UDP Agent (Windows) will install drivers for critical unknown devices. If the device already has a driver installed, Arcserve UDP Agent (Windows) will not update that driver again. For some devices, Windows 7PE may have the drivers for them, but these drivers may not be the best ones and this can cause the BMR to run too slow.

To remedy this problem, perform one of the following tasks:

Check if the driver pool folder contains the newest disk drivers. If it does, and you are restoring to the original machine, please install the new driver from the driver pool folder. If you are restoring to alternate machine, download the latest disk drivers from the Internet, and load it before you start data recovery. To load the driver, you can use the "drvload.exe" utility, which is included in Windows PE.
Change the device operating mode from "AHCI" (Advanced Host Controller Interface) to Compatibility mode. (Compatibility mode provides a better throughput).
