You can use several features to improve system performance.
Managing storage system resources by using FlexShare
FlexShare enables you to use priorities and hints to increase your control over how your storage system resources are used. This control enables you to consolidate workloads without negatively impacting critical applications.
Increasing WAFL cache memory
You can increase Write Anywhere File Layout (WAFL) cache memory in a system that has a caching module installed (Performance Acceleration Module (PAM), Flash Cache module, or Flash Cache 2 module). To increase the WAFL cache memory, you use the WAFL external cache, a software component of Data ONTAP.
Improving read performance
You can improve the read performance of your storage system by enabling read reallocation on volumes. Read reallocation is disabled by default.
Improving write performance
You can enable free space reallocation on aggregates to improve write performance. Free space reallocation improves write performance by optimizing the free space within an aggregate. Free space reallocation is disabled by default.
