Applies to

  • ONTAP 9
  • All FAS and AFF models

Answer

  • Different operations within the same application may require a different IOP limit
    • It depends on the workload type, as databases will have different i/o requirements than home directories
  • There is not one answer as IOP types are different based upon read, write, and other
    • Other IOPs have variable impact depending on type
    • For example, a RMDIR will take more CPU cycles and disk cycles than an Access operation
  • Example:
    • Copying large files to ONTAP may be  512kB writes and may only get 10,000 IOPs
    • Reading lots of small files may be an average of 4 kB read IOPs and can get 70,000 IOPs
    • That same controller may do 500,000 NFSv3 Access operations

 

Additional Information

Is it possible to get each aggregate's max theorical iops and bandwidth?
