Advantages of four paths to an array LUN

Contributors netapp-chikkusu

When planning the number of paths to an array LUN for ONTAP, you need to consider whether you want to set up two or four paths.

The advantages of setting up four paths to an array LUN include the following:

  • If a switch fails, both storage array controllers are still available.

  • If a storage array controller fails, both switches are still available.

  • Performance can be improved because load balancing is over four paths instead of two.
