System performance and resources

Data ONTAP offers features that enable you to manage your system resources, improve your system performance, optimize data layout, and archive performance data.

• How to manage storage system resources by using FlexShare
  The FlexShare tool is provided by Data ONTAP to enable you to use priorities and hints to increase your control over how your storage system resources are used.
• How to increase WAFL cache memory by using FlexScale
  You can increase Write Anywhere File Layout (WAFL) cache memory in storage systems running Data ONTAP by using FlexScale, which includes the Performance Accelerator Module as the hardware component and the WAFL extended cache as the software component. FlexScale needs to be licensed.
• Ways to improve storage system performance
  You can take configuration procedures to improve your system's performance.
• How to optimize LUN, file, volume, and aggregate layout
  You can optimize the existing layout of a LUN, a file, a volume, or an aggregate.
• How to improve Microsoft Exchange read performance
  In Microsoft Exchange environments, you can use the Exchange eseutil tool to perform database scans for validation purposes. Exchange database scans usually access data by using a sequential read pattern. By enabling logical extents, you improve Exchange sequential read performance and database validation time.
