Instructions For Migrating Bonded Interfaces In A San Cluster From 1 Gbe; To 10 Gbe Ethernet; Overview; Best Practice - HP StorageWorks P4000 Series Manual

1 Instructions for migrating bonded
interfaces in a SAN cluster from 1 GbE to
10 GbE Ethernet

Overview

The 10 GbE feature option adds 10 GbE to the HP StorageWorks P4000 platforms. This is an add-on
feature to the standard 1 GbE dual Ethernet adapters built into the system boards of the P4000 storage
nodes. After the 10 GbE dual port Ethernet adapter is installed and configured, users see four Ethernet
interfaces listed in the Centralized Management Console (CMC) TCP/IP Network tab window. These
four interfaces can be bonded a number of ways.

Best Practice

We recommend bonding network interfaces for performance and failover. The best bond to use
depends on your network and SAN configuration.

Bonding 10 GbE interfaces

After installing the 10 GbE upgrade, you have a choice of supported bond configurations. Note that
not all the bond configurations which are supported by the HP LeftHand Storage Solution are supported
with the 10 GbE upgrade.

Supported bonds with 10 GbE

The P4000 with the 10 GbE feature installed and configured supports these bond types.
• Adaptive Load Balancing (ALB) bond with the two 10 GbE Ethernet NICs
• Active-Passive bond with two 10 GbE Ethernet NICs
• Active-Passive bond with 1 GbE NIC and 10 GbE NIC
• Link Aggregation Dynamic Mode (802.3ad) bond with two 10 GbE Ethernet NICs

Unsupported bonds with 10 GbE

The HP StorageWorks P4000 with the 10 GbE feature installed and configured does not support the
following bond types:
• Bonding two bonds
• ALB bond with 1 GbE NIC and 10 GbE NIC
