Ethernet Switch Models - Cluster Roles - HP Cluster Platform Introduction v2010 Introduction Manual

• An administrative subnetwork handles management and installation tasks, and isolates the
administration traffic from application traffic in an HP Cluster Platform.
• A console network provides node operations such as booting and shutdown. This network
is connected to the server's dedicated management processor (MP) network port.
• An interconnect management network. Each interconnect provides an Ethernet port in its
controller card, enabling remote access to the switch management firmware. For clusters
that contain multiple interconnects, all controller cards are networked together through this
third Ethernet network in the cluster.
Nodes are connected to the administrative and console networks through a flat-tree hierarchy
of Ethernet switches. The networks are described in the Cluster Platform Overview. The cluster
uses the following switch models for its internal Ethernet networks:
• HP ProCurve 2610 series (see
• HP ProCurve 2650 and 2626, used in older Cluster Platform configurations (see
• HP ProCurve 2848 and 2824 (see
Table 2-4 shows the potential roles that each switch model can undertake in the cluster. The
application of a model to a role depends on the size and density of the cluster. See the Ethernet
Network Cabling Tables for more information.
