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 P4000 Series 1 GbE to 10 GbE Migration Guide 7
