Table 5-1 HP Cluster Platform Terminology (continued) HP Cluster Platform Windows Compute Cluster Definition Term Term interconnect technology Only InfiniBand and Gigabit Ethernet are supported. The type of communications protocol and link implemented in an interconnect. See Quadrics, Myricom, Infiniband, and Gigabit Ethernet. internal network Windows clusters do not A cluster has two internal networks used for low-speed distinguish a separate communication between nodes. See administrative network and administrative network console network. and console network KVM A rack-integrated workstation (keyboard, video, and mouse) enabling you to administer the cluster locally when necessary for tasks such as upgrading firmware and installing software. (You perform most run-time administration tasks by using a remote login from a client.) KVM switch An optional multiport (4 or 8) switch that enables you to switch the connection between the KVM and a utility node. LAN See external network. link A physical connection between a port on the interconnect and a port on an HBA that is located in the node's PCI bus. local workstation See KVM. low-speed network Windows clusters do not The internal Ethernet networks are called "low speed" only to distinguish a separate differentiate them from the interconnect's nonblocking high-speed administrative network network. This term is relative, because the Ethernet network and console network switches used might be fast Gigabit Ethernet. management network Windows clusters do not See administrative network. distinguish a separate administrative network and console network management port A connection or device that is part of the interconnect, enabling you to connect to it and administer it. You use the control processor for tasks such as assigning TCP/IP addresses, loading firmware or running interconnect diagnostics. module (*BB) Windows clusters do not A number of components of similar function connected into a support utility building functional unit and installed in a single rack. A module can be a blocks (UBB) or utility CBB, IBB, UBB, or UXR. expansion racks (UXR) modular cluster Windows clusters do not A configuration designed to customer specifications by using support utility building CBBs, IBBs, UBBs, and a single UXR. Modular clusters can be blocks (UBB) or utility upgraded (expanded). expansion racks (UXR) network interface card Each node has at least two integrated network interface cards (NICs). One NIC might be dedicated to the server's console. These NICs are used for connections to the internal networks. network topology HP Cluster Platform The architecture of the cluster networks. In HP Cluster Platform supports only a subset of there can be two low-speed networks and one high-speed the topologies supported network. The connections between any node and these networks by Windows Clusters. determine their function. NIC See network interface card. node Head node and compute An individual server, which can be a control node \, an node. (Utility nodes are application node or a utility node. not supported). 25
