Owner's Manual

Table 4 shows a sample volume configuration. Create volumes in PS5000XV

array and create access list to allow all host iSCSI network interfaces to access the

volumes. For example, the following volumes are created:

mdi-ocr-css-spfile

mdi-data1

mdi-data2

mdi-fra1

Configuring iSCSI Networks

Dell recommend configuring the host network interfaces for iSCSI traffic to use

Flow Control and Jumbo Frame for optimal performance. Use the ethtool

utility to configure Flow Control.

Use the following command to check for Flow Control (RX/TX Pause) on the

interfaces:

# ethtool -a <interface>

For example:

# ethtool -a eth2

Pause parameters for eth2:

Autonegotiate: on

RX: on

TX: on

This example shows that Flow Control is already turned on. If it is not turned

on, use the following command to turn on Flow Control:

# ethtool -A <interface> rx on tx on

Jumbo Frame is configured in the /etc/sysconfig/network-

scripts/ifcfg-<interface> scripts, by adding the MTU="<mtu-

value>" parameter.

The example below shows MTU set to 9000.

# cat /etc/sysconfig/network-scripts/ifcfg-eth2

DEVICE=eth2

HWADDR=00:15:17:80:43:50

ONBOOT=yes

TYPE=Ethernet
