Trace analysis provides insights into workload properties and IO patterns, which are essential for storage system tuning and optimizing. This chapter discusses how the workload interacts with system components, algorithms, structures, and applications.
Interactions with Components
As discussed in Chapter 1, different storage devices may have large different properties. In addition, their internal structures and algorithms also have significant impacts on the final performance. For example, write cache of HDDs can gain benefits from data locality:
Write cache hits can avoid some disk mechanical ...
