Deployment Guide

NOTE: If using jumbo frames, they must be enabled and configured on all devices in the data path, adapter ports,

switches, and storage system.

e. If the host uses network adapters for iSCSI traffic, add the VMkernel ports to the iSCSI software initiator.

f. Use the iSCSI cabling diagrams to cable the host servers to the switches. Connecting host servers directly to the storage

system without using Ethernet switches is not supported.

Two iSCSI Networks with Dual 10 GbE 2–Port Storage Controllers

Use two iSCSI networks to prevent an unavailable port, switch, or storage controller from causing a loss of connectivity between

the host servers and a storage system with dual 10 GbE 2-port storage controllers.

About this task

This configuration includes two fault domains, two iSCSI networks on separate subnets, and two Ethernet switches. The storage

controllers connect to each Ethernet switch using one iSCSI connection.

• If a physical port or Ethernet switch becomes unavailable, the storage system is accessed from the switch in the other fault

domain.

• If a storage controller becomes unavailable, the virtual ports on the offline storage controller move to the physical ports on the

other storage controller.

Steps

1. Connect each server to both iSCSI networks.

2. Connect fault domain 1 (shown in orange) to iSCSI network 1.

• Storage controller 1: port 1 to Ethernet switch 1

• Storage controller 2: port 1 to Ethernet switch 1

3. Connect fault domain 2 (shown in blue) to iSCSI network 2.

• Storage controller 1: port 2 to Ethernet switch 2

• Storage controller 2: port 2 to Ethernet switch 2
