3.3 Modular Packaging Configuration

A Modular Packaging Configuration is built from the UBB and VBB rack systems. It has the

following components as summarized in Chapter 2:

• Render and Display nodes.

Workstations: xw8200, xw8400, or xw9300 or servers: DL140 G3.

• Head node.

DL380 G4 or a DL385 G4 server.

• Optional KVM.

• System Interconnect and Administrative Network (found in HP Cluster Platform systems,

and thus not unique to the SVA).

The head node is a typical node type found in HP Cluster Platform systems. The server head

node must have the same architecture as any workstations in the cluster.

3.4 Network Configurations

This section describes the different networks used in the SVA.

3.4.1 System Interconnect (SI)

The SI for visualization nodes can be GigE, InfiniBand, or Myrinet. When the visualization nodes

are integrated with compute nodes, the choice of SI is usually determined by the requirements

of the compute nodes.

3.4.2 Administrative Network Connections

A GigE interconnect serves as the Administrative Network to control the operation of the cluster

(for example, boot, shutdown, restart) and to control the running parts of a distributed application

(for example, launching and stopping processes).

The SVA adds visualization capability to an HP XC cluster; therefore, the Administrative Network

is implemented with the logical configuration defined by the HP XC and Cluster Platform

architectures. However, the physical implementation differs.
