Concepts and Management
Optimizing Performance
Controller Data Path
The data path through the controller is designed to transfer data between the disks and the host as
efficiently as possible. However, under heavy I/O loads, bottlenecks may form in the data path. These
bottlenecks can frequently be reduced by adding more hardware resources, such as cache RAM or disks.
Figure 26. Data Path
The controller continually monitors various points along the data path to determine how efficiently data is
moving. These measurements form the metrics used to identify performance problems and make
recommendations for their solution.
