Setup Guide

iSCSI Configuration

This section describes the recommended configuration that should be applied when attaching hosts to a PowerStore cluster

using iSCSI.

NOTE: This section applies only for iSCSI. If you are using only Fibre Channel with vSphere and PowerStore, go to Fibre

Channel HBA Configuration.

NOTE: Be sure to review iSCSI SAN Guidelines before you proceed.

Pre-Requisites

Before configuring iSCSI, the following pre-requisites should be met:

● Follow the VMware recommendations for installation and setup of the appropriate NIC/iSCSI HBA for your system.

● It is recommended to install the latest driver version (patch), as described in the VMware support site for each specific NIC/

iSCSI HBA.

● Refer to the E-Lab interoperability Navigator (https://elabnavigator.emc.com) for supported NIC/iSCSI HBA models and

drivers.

Software iSCSI Adapter Configuration

This topic provides a high-level procedure for configuring the iSCSI adapter on ESXi hosts connected to PowerStore.

About this task

For further details on this topic, refer to the VMware vSphere documentation for the ESXi version installed on the ESXi hosts.

As noted in the iSCSI SAN Guidelines section, PowerStore system supports only a single subnet for all iSCSI communication.

Steps

1. Create a single vSwitch comprised of two uplink physical ports.

2. Create two VMkernel ports on the same subnet as the storage cluster iSCSI portals (the communication must not be

routable).

Example:

● iSCSI-A-port0 1.1.1.1/24

● iSCSI-A-port1 1.1.1.2/24

● iSCSI-B-port0 1.1.1.3/24

● iSCSI-B-port1 1.1.1.4/24

● vmk1 1.1.1.10/24

● vmk2 1.1.1.11/24
