There is no direct answer for this question but we shall do it in several way. 

• If volume/lun present in ATA/SATA harddisk aggregate, then the volume can be migrated to FC/SAS disk aggregate. Either you can use flash cache to improve performance.
• For NFS/CIFS instead of ACCESSING from single INTERFACE, multi mode vif can be configured to get better bandwidth and fault tolerance.
• Always advised to keep aggr/vol utilization below 90%.
• Avoid doing multiple volume backup in single point of time.
• Aggr/volume/lun reallocation can be done to re–distribute the DATA to multiple disk for better striping performance.
• Schedule scrubbing and De-duplication scanning after business hours.
• Create multiple loops and connect different types of shelf's to each loop
• Avoid mixing up different speeds of disk and different types of disk in a same aggregate.
• Always keep sufficient spare disk to replace in case of disk failure. Because reconstruction time will take more time and cause negative performance.
• Keep the advised version of firmware/software which is recommended by NETAPP.
