Hi,

I have few question regarding Virtual Data Mover (VDM) and Physical Data Mover (PDM) for NFS.

The environment is very small with one or two NFS client's. There is VNX5200 with two DM Servers and one Control Station.

1) Which one is best and easy to manage, VDM or PDM for NFS.

2) Going through the document I came across the following:

   A user can export NFS through a Data Mover rather than a VDM because the VDM functionality does not support NFS. If a VDM is unmounted or moved to another Data Mover, NFS exports of the mounted file systems on that VDM will be invalid. A user must reconfigure NFS exports if a VDM is moved to another Data Mover.

Is there any way to overcome the above issue?

3) I am planning to configure the PDM in active-standby mode. If failover happens does all the filesystems move to another PDM if I configure NFS on VDM without any issues. And without any admin intervention the NFS exports should be available on the other VDM.

4) Which one is best for NFS, VDM’s network interface or PDM’s network interface?

Praveen.
