See Chapter 14, “Data migration in zSeries environments” on page 293 for a complete
discussion of the different methods available for data migration from any other disk system to
the DS8000 family.

9.6 Planning for performance

IBM TotalStorage DS8000 is a 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

Size of cache storage

Number of channels

Remote Copy

Parallel Access Volume

I/O priority queuing

Monitoring performance

Hotspot avoidance

Balance I/O activity
