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, xw9300, xw9400, or servers: DL140 G3 or DL145 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.
