We are planning to migrate DataStage EE installation from IBM P655 servers to IBM P595 servers. Are you aware of any known issues with this p595 servers w.r.t DataStage EE?
We are also planning to use the virtualization capabilities in these servers.
If anyone had been involved in any such activity before, I would appreciate sharing any lessons learnt...
Thanks in advance

Ramesh,
DataStage has no idea what hardware lies at the base of the system, the lowest virtual machine layer that it sees is the OS. In this case the OS remains the same with AIX and thus going from one p-series to another is transparent to DataStage.
If you mean LPARs and dynamic switching of CPUs and memory by virtualization then by all means go ahead. I think that turning on the p-series multithreading affects the DataStage licensing as it effectively doubles the number of processors that DataStage see but I doubt that there will be a performance change.
