Before going to the question I want to provide some details of our present system architecture- Now we have some questions as we plan to buy new AIX servers for test and production environments for our ETL codes
(Datastage and Business Objects). Previously we had AS400 machines handling all IT systems. ETL concept is new in our organization and I am trying to implement it. Though the databases we plan to keep in AS400 servers, we plan to have Datastage Server Edition and Business Objects dev, test and prod environment in AIX. Currently we have only a development environment in AIX where currenly four projects are in development mode. The current system is a 2 CPU , 60 GB system for initial implementation.
I have got some information from Datastage guide and on that basis we have our temporary development environment.
My question:
For each environment say Development, Test and Prod how to determine the following:
Code: Select all
1> How many CPU we should have for each environment
2> How many nodes we need
3> How much diskspace - temp, free space etc for each environment
4> What other components we need to think of while buying a AIX server for Datastage
