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
