Answer

This document outlines the direct attach configuration with NetApp E-Series Array for a Stretch MetroCluster.

Direct Attach is supported only with NetApp E-Series Array in a Stretch MetroCluster configuration starting from Clustered Data ONTA

P 8.3.1
For all other supported arrays, you must use FC switches for connecting array LUNs to the Data ONTAP systems.

Supported Direct Attach configuration:

  1. Stretch MetroCluster with only NetApp E-Series Array LUNs
  2. Stretch MetroCluster with both NetApp E-Series Array LUNs and NetApp native disks where NetApp Native Disks are connected via Optical SAS cables.
  3. Stretch MetroCluster with both NetApp E-Series Array LUNs and NetApp native disks where NetApp Native Disks are connected via FC to SAS bridges.

 

Examples of Direct Attach configuration for Stretch MetroCluster (MCC) with NetApp E-Series array LUNs:
In a stretch MetroCluster configuration with NetApp E-Series Array LUNs, you must cable each controller's HBA ports to target ports on the corresponding NetApp E-Series Array Controllers.
