Running SAP XI in High Availability

22 Views

Bonjour a vous tous !

I am looking for best practices when running SAP Exchange Infrastructure (3.0, well it is now XI 7.0 with the new NW2004s – SP9) in High Availability mode.

The customer that I work with does not know yet on which platform its production environment will be (Unix/Oracle vs Microsoft/SqlServer 20005). I know that some hardware vendor has built-in HA capabilities, either Software/Hardware based (MSFT MCS, IBM HACMP, etc).

Should we go for an "SAP XI all-In One" installation or distributed one ? Should we get one central SLD or one per environment? What is the role of the SLD and Solution Manager? Do they need to be interconnected?

I have worked with other EAI middlewares (Biztralk Server and webMethods) and normally the Integration Engine sit on it's own server and the various adapters are on their respective servers (i.e.: one server for HTTP, one server for FTP, one server for EJB, etc), since the sizing (RAM. Java heap memory, etc) for all theses adapters are different (FTP a lot of small file, EJB not so many request, but they could eat-up a lot of CPU, etc). Is this a best practice that I can apply also with SAP XI ?

Thank in advance for you help !
