We need to install datastage version 7.1 Enterprise edition on a Sun Solaris Unix box. Can anybody throw light on the following queries:
Whether machine with SMP architecture is better or MPP architecture is better for EE.
We want to use extensively the parallel extender facility available with EE.
Thanks

SMP = Single big box with many CPUs, all running under one OS.
MPP = Many boxes with few/many CPUs, all networked together.

Both formats are well supported by DataStage Enterprise Edition. Each have their own advantages and disadvantages. Grid computing is a MPP concept that are being advocated by Oracle (despite not working TOO well in that avenue -- it's all marketing). It is also something that can be easily done with Orchestrate, but at a certain point, the network and the engine overheads will kill your performance, no matter how well distributed your job is designed.
It all is a factor of what your company need to have done, and what your company are willing to invest on.
I personally am very familiar with SMP, with only topical knowledge of MPP systems. Both works pretty well, with SMP providing the best performance of the two equally-numbered CPU systems, especially if you optimize your disk array for performance.
