5. Embedded network interface card NIC 2, RJ-45 port which is optionally connected by a CAT5e cable to the local network (LAN). 6. Embedded network interface, connected by a CAT5e cable to the HP ProCurve administrative network switch. This connection enables cluster management tasks such as job submission and monitoring. 7. Optional redundant power supplies. 1.4.6 Connecting to an External Network An optional connection to an external 10/100/1000Base-T network is supported from the control node using NIC2. Connecting to an external network depends on the type of CPE configuration, as follows: • CP Workgroup System with single-density server blades (see Section 1.4.6.1) • CP Workgroup System with double-density server blades (see Section 1.4.6.2) • CPE BladeSystem configurations with an external rack-mountable server control node (see Section 1.4.6.3) • CPE BladeSystem configurations with double-density server blades and an external rack-mountable server control node (see Section 1.4.6.4) • CPE BladeSystem configurations with a single-density server blade control node (see Section 1.4.6.5) • CPE BladeSystem configurations with a double-density server blade control node (see Section 1.4.6.6) • CPE with rack-mountable servers only (see Section 1.4.6.7) Title: The following sections show the combined Administrative, Console, and Gigabit Ethernet network connections in addition to the options for connecting CPE clusters to an external network. 1.4.6.1 CPE Workgroup System with Single-Density Server Blades If the control node is a single-density server blade and the configuration uses an HP BladeSystem c3000 enclosure, both NIC1 and NIC2 of the server blade are routed to IMB1. A connection to an external network can be made to one of the external ports on the HP GbE2c switch installed in IMB1. The intention is for traffic to the external network to be routed through NIC2 on the control node blade. Since both of the server blade connections to the Administrative network and the control node's connection to the external network are through the same switch, the cluster must be configured with a suitable addressing scheme to separate the administrative port addresses (NIC1) from the external network addresses. Additional separation may be achieved by configuring a VLAN with switch ports 1-8 as members (see Section 2.6 for more information). Caution: Set up the VLAN carefully and in accordance with the procedures described in Section 2.6 to ensure that access to the switch management functions is available over the required network. Figure 1-12 shows the connection to an external network for a configuration using a c3000 enclosure and a single-density server blade control node. 26 Cluster Platform Express Overview

1.4.6 Connecting to an External Network
An optional connection to an external 10/100/1000Base-T network is supported from the control
node using NIC2. Connecting to an external network depends on the type of CPE configuration,
as follows:
•
CP Workgroup System with single-density server blades (see
Section 1.4.6.1
)
•
CP Workgroup System with double-density server blades (see
Section 1.4.6.2
)
•
CPE BladeSystem configurations with an external rack-mountable server control node (see
Section 1.4.6.3
)
•
CPE BladeSystem configurations with double-density server blades and an external
rack-mountable server control node (see
Section 1.4.6.4
)
•
CPE BladeSystem configurations with a single-density server blade control node (see
Section 1.4.6.5
)
•
CPE BladeSystem configurations with a double-density server blade control node (see
Section 1.4.6.6
)
•
CPE with rack-mountable servers only (see
Section 1.4.6.7
)
Title:
The following sections show the combined Administrative, Console, and Gigabit Ethernet network
connections in addition to the options for connecting CPE clusters to an external network.
1.4.6.1 CPE Workgroup System with Single-Density Server Blades
If the control node is a single-density server blade and the configuration uses an HP BladeSystem
c3000 enclosure, both NIC1 and NIC2 of the server blade are routed to IMB1. A connection to
an external network can be made to one of the external ports on the HP GbE2c switch installed
in IMB1. The intention is for traffic to the external network to be routed through NIC2 on the
control node blade. Since both of the server blade connections to the Administrative network
and the control node’s connection to the external network are through the same switch, the cluster
must be configured with a suitable addressing scheme to separate the administrative port
addresses (NIC1) from the external network addresses. Additional separation may be achieved
by configuring a VLAN with switch ports 1-8 as members (see
Section 2.6
for more information).
Caution:
Set up the VLAN carefully and in accordance with the procedures described in
Section 2.6
to
ensure that access to the switch management functions is available over the required network.

shows the connection to an external network for a configuration using a c3000
enclosure and a single-density server blade control node.
