About This Document This document describes how to prepare the nodes in your HP cluster platform before installing HP XC System Software. An HP XC system is integrated with several open source software components. Some open source software components are being used for underlying technology, and their deployment is transparent. Some open source software components require user-level documentation specific to HP XC systems, and that kind of information is included in this document, if required.

1 Hardware and Network Overview The following topics are addressed: • • • • • • “Important Information About HP XC Systems with HP Server Blades and Enclosures” (page 15) “Supported Cluster Platforms” (page 15) “Supported Console Management Devices” (page 16) “Administration Network Overview” (page 17) “Administration Network: Console Branch” (page 17) “Interconnect Network” (page 17) 1.
1.3 Supported Console Management Devices Table 1-2 lists the supported console management device for each hardware model within each cluster platform. The console management device provides remote access to the console of each node, enabling functions such as remote power management, remote console logging, and remote boot. HP workstation models do not have console ports. HP ProLiant servers provide remote management features through a baseboard management controller (BMC).
1.4 Administration Network Overview The Administration Network is a private network within the HP XC system that is used primarily for administrative operations. This network is treated as a flat network during run time (that is, communication between any two points in the network is equal in communication time between any other two points in the network).
Table 1-3 Supported Interconnects Gigabit Ethernet InfiniBand® PCI-X CP3000 X X CP3000BL X CP4000 X X CP6000 X X Cluster Platform and Hardware Model InfiniBand PCI Express Single Data Rate and Double Myrinet® (Rev. D, Data Rate (DDR) E, and F) X QsNetII® X X X X X X Mixing Adapters Within a given family, several different adapters can be supported. However, HP recommends that all adapters must be of one type only; a mix of both types of adapters is not supported.
2 Making Node and Switch Connections This chapter provides information about the connections between nodes and switches that are required for an HP XC system. The following topics are addressed: • • • • “Cabinets” (page 19) “Trunking and Switch Choices” (page 19) “Switches” (page 20) “Interconnect Connections” (page 28) IMPORTANT: The specific node and switch port connections documented in this chapter do not apply to hardware configurations containing HP server blades and enclosures.
For physically small hardware models (such as a 1U HP ProLiant DL145 G1 server), a large number of servers (more than 30) can be placed in a single cabinet, and are all attached to a single branch switch. The branch switch is a ProCurve Switch 2848, and two-port trunking is used for the connection between the Branch Administration Switch and the Root Administration Switch.
Root Console Switch, Branch Administration Switch, Branch Console Switch, This switch connects to the Root Administration Switch, Branch Console Switches, and connects to the management console ports of nodes in the utility cabinet. This switch connects to the Gigabit Ethernet ports of compute nodes and connects to the Root Administration Switch. This switch connects to the Root Console Switch and connects to the management console ports of the compute nodes.
Figure 2-2 Node and Switch Connections on a Typical System Specialized Role Nodes Head Node Administration Switches Console Switches Root Administration Root Console Br anch Switches Br anch Switches Compute Nodes Figure 2-3 shows a graphical representation of the logical layout of the switches and nodes in a large-scale system with a Super Root Switch.
HP workstations connected to the Root Administration Switch must be connected to the next lower-numbered contiguous set of ports immediately below the nodes that have console management ports. For example, if nodes with console management ports are connected to ports 42 through 36 on the Root Administration Switch, the console ports are connected to ports 42 through 36 on the Console Switch.

3. 4. 5. 6. Connections to node administration ports start at port 21 (descending). Port 22 is used for the administration port of the head node. Dual personality ports. Port 24 is used as the interconnect to the Root Console Switch (a ProCurve 2650 or ProCurve 2626 model switch).
Allocate the ports on this switch for consistency with the administration switches, as follows: • Ports 1–10, 13–22, 25–34, 37–41 — Starting with port 1, the ports are used for links from Branch Console Switches. Trunking is not used. — Starting with port 41 and in descending order, ports are assigned for use by individual nodes in the utility cabinet. Nodes in the utility cabinet are connected directly to the Root Administration Switch.

The head node in an HP XC system is always the node connected to the highest port number of any node on the Root Administration Switch and the Root Console Switch. NOTE: The head node port is not the highest port number on the Root Administration Switch. Other higher port numbers are used to connect to other switches. If the Root Administration Switch is a ProCurve 2848 switch, the head node is connected to port number 42, as discussed in “Root Administration Switch” (page 23).
