HP Virtual Connect for c-Class BladeSystem Version 3.00 Setup and Installation Guide for HP Integrity BL8x0c i2 Series Server Blades, Fifth Edition

Installation 58
Networks must be defined within the Virtual Connect Manager so that specific, named networks can be
associated with specific external data center connections. These named networks can then be used to
specify networking connectivity for individual servers. For more information on defining Ethernet networks
and on server connections, see the HP Virtual Connect for c-Class BladeSystem User Guide.
The following sections provide an overview of the types of external connections and their behaviors.
Mapping individual networks to individual external uplink ports
The simplest approach to connecting the defined networks to the data center is to map each network to a
specific external uplink port. This uplink port is defined by the following:
• Enclosure name
• Interconnect bay containing the for HP Integrity BL8x0c i2 Series Server Blades
• Selected port on that module
Port status indicators can be used to locate a specific port or to provide additional status.
The following table shows an example of simple network mapping, where the Virtual Connect enclosure is
named Enclosure1 and Virtual Connect Ethernet modules are in interconnect module bays 1 and 2.
Network Uplink port
Production_Network Enclosure1:Bay1:PortX2
Dev_Network Enclosure1:Bay1:Port4
Backup_Network Enclosure1:Bay2:Port3
iSCSI_Storage_Network Enclosure1:Bay2:PortX2
In this case, the Ethernet packets are passed unchanged between the server blades and the external
networks. Any VLAN tags added by the server or external switch are ignored and pass through the for HP
Integrity BL8x0c i2 Series Server Bladess.
Mapping a single network to multiple uplinks (uplink port set)
A single network can be mapped to more than one external uplink port to provide improved throughput
and availability, referred to as an uplink port set. Review the following guidelines before mapping a
single network to an uplink port set:
