Create network user with remote home folder

I have Mac Server with OpenDirectory configured. Then I create some network users with home folder located on server. Due to the high bandwidth of user usage, I want to add another server that only host user home folders, so the traffic transferred between user and new server while authentication still via old server.
Is this possible to do that? If not, is there any walk around that fix my issue?

Yes this is possible. When prompted for the location of the home folder for the user you can choose any shared folder that you have configured to be used as storage for home folders in the File Sharing service. This folder can be anywhere on the machine or anywhere on the network.
