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 well-balanced disk system
the following components that affect performance need to be considered:

Disk Magic

Number of ports

Remote Copy

Parallel Access Volumes (z/OS only)

I/O priority queuing (z/OS only)

Monitoring performance

Hot spot avoidance

Preferred paths

8.6.1 Disk Magic

An IBM representative or an IBM Business Partner may model your workload using Disk
Magic before migrating to the DS6000. Modelling should be based on performance data
