Array OS Conditions

The following conditions apply when using Microsoft Offload Data Transfer (ODX) with an array:

• If you upgrade the array OS from a pre-ODX release to an ODX release, Windows may not view the volume as ODX-capable. This is recognized by Microsoft as a Windows limitation. In this situation, reboot the Windows host to see the volume as ODX capable.
• ODX performance on a multi-array group may be slightly slower than when using the regular copy mechanism because of an inherent forwarding activity.
• During bin migration, ODX operations can be stopped and the regular copy mechanism will take effect.
• ODX fast copy is not supported if the destination volume has synchronous replication enabled.
