An existing IBM customer has a few pSeries servers running DB2 on AIX in their environment. The DB2 application contains the database for an order entry application. An xSeries SQL database server replicating from DB2 is added for off-line analysis purposes. The customer wants to know if consolidating the storage and centralized backup is possible. What are the options available to accomplish this？（）

A. pSeries and xSeries use different file systems. Consolidating Storage and backup is not achievable.
B. Consolidation is possible by connecting pSeries local storage to the xSeries SQL server using the IXA adapter.
C. Storage consolidation can be achieved by connecting the pSeries and xSeries servers to a common DS4000 storage server.
D. Storage consolidation is only achievable when raw file systems are used by the databases and both servers run the same Linux file system （e.g.， EXT3 or Reiser）.
