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 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
