The answer of SAS TS as you noted is a disappointing one. They are selling SAS able to run on some systems.
As a DR and BCP plans are often mandatory for Information technology that is a environment to be supported.
How you are designing and implementing a DR approach is dependent of your in house ICT policies.
One prereq to review Is licensing. In clustered approach all machines are part as real operational. They should all be licensed.
In a cold/hot standby there is some machine that will only be go into life when there is a disaster. To be able that the DR plan is working you should be able to verify that process. http://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32009L0024&from=EN (article 5.3 and 6.1-2) are covering the DR testing interoperability (EC). When there is nothing in in the contracts (not supported) it should be permitted by SAS, otherwise they are violating this directive.
So you have a cold DR environment. Tat one should be designed tested and implemented and verified at regular intervals as of regulations..
One thing to do is either:
- isolating that in dedicated network segment allowing using the same DNS names. A dedicated DNS server in the DR environment could be very handy.
- Doing a smart relocation of all data and DNS to another machine. This is described by SAS for 9.3 with LSF orchestrator.
Your data can be as good as nearly real time shadowed (duplicated SAN solutions) or on daily intervals.
The real problematic issue to get the duplicated machine having all needed data of >>ALL<< components.
Even a good Backup/Reststore is not very clear and reliable with SAS solutions. Saskiwi mentioned that already.
