Figure 8-14 Different data migration methods
See Chapter 13, “Data Migration in zSeries environments” on page 251 for a complete discussion of the different methods available for data migration from any other disk system to the DS6000 series.
8.6 Planning for performance
The IBM TotalStorage DS6000 is a cost effective, high performance, high capacity series of disk storage that is designed to support continuous operations and allows your workload to be easily consolidated into a single storage subsystem. To have a
