Subodh,
Delphix does not support Netezza, and I do not know if there are plans to add Netezza to our product "roadmap", but even if there is not, there is a "toolkit" to support the virtualization of the file-systems on which Netezza database files are located, so there is the possibility of using this toolkit to create your own custom virtualization solution?
If you're interested in learning more about this custom solution, please start with our documentation for "
unstructured files"? Once you have the general idea from that, then please contact us on the community here for more information and guidance?
Hope this helps!
