Sorry, just saw that you are on NetWorker 7.5 and not 7.6 - the equivalent information for NetWorker 7.5 is in the 7.5 Administration Guide:

"

The NetWorker NDMP interface is an optional feature that must be licensed
separately from the NetWorker base product according to a tiered licensing structure.
One NDMP Client Connection license must be applied to each NAS array, although a
single host can have multiple Client resources.
Use of the NetWorker storage node software with NDMP support requires a software
license (where the NetWorker NDMP interface is not used).
Additionally, a file type device is supported for NDMP operations, which can also be
used as a bootstrap device. A DiskBackup license is required for the file type device.

From the NetWorker 7.6 Licensing Guide:

NDMP licensing
The NetWorker NDMP interface is an optional feature that must be licensed
separately from the NetWorker base product according to a tiered licensing structure.
The following apply to NDMP licensing:
◆ One NDMP Client Connection license is required for each NDMP host.
◆ For NAS arrays, where each host in the array shares one license, you can specify
the user-defined array name in the NDMP array name attribute of the Client
resource.
◆ When the NetWorker NDMP interface is not used, a storage node license is
required to use the NetWorker storage node software with NDMP.
◆ Additionally, a file type device is supported for NDMP operations, which can also
be used as a bootstrap device. A DiskBackup license is required for the file type
device.

Is this what you're looking for or do you need something else?

I have received a copy of the Networker Hardware Comaptibility Guide. ON page 163 there is a list of NDMP Tiers shoing the hardware associated with each tier. In my case the celerra ns120 is Tier 2.

Thanks, Mark
