Stages of implementation for a system using array LUNs

Contributors netapp-chikkusu

Implementing a configuration in which your system uses LUNs from a storage array has two stages: a back-end implementation and a front-end implementation. It is helpful when planning your configuration to understand the high-level tasks in each stage.

Stage 1: back-end implementation

Setting up the back-end implementation includes all tasks that are required to set up the ONTAP system with a storage array, up to the point where you can install ONTAP software.

Tasks to set up the back-end implementation include the following:

  1. Creating and formatting array LUNs

  2. Assigning ports

  3. Cabling

  4. Zoning switches (if applicable)

  5. In ONTAP, assigning specific array LUNs to an ONTAP system

  6. In ONTAP, providing information to set up an ONTAP system on the network

  7. Installing ONTAP software

If an ONTAP system is ordered with disk shelves, the ONTAP software is installed by the factory. In such a configuration, you do not need to create the root volume and install licenses and ONTAP software.

If an ONTAP system is ordered without disk shelves, you need to configure ONTAP before setting up the cluster.

Stage 2: front-end implementation

Tasks to set up the front-end implementation are the same as for a system using disks, including the following:

  • Configuring the ONTAP system for all protocols (NAS, FC, or both)

  • Configuring ONTAP features such as SnapVault, SnapMirror, SnapValidator, and Snapshot copies

  • Creating volumes and aggregates

  • Setting up data protection, including NDMP dumps to tapes
