I
InfiniBand An interconnect protocol and connection type supported by interconnect technology from
Voltaire that complies with the specification defined by the InfiniBand trade group.
Interconnect A module containing one or more interconnects.
Building Block
(IBB)
J
Job Scheduler The Job Scheduler service runs on the head node and is responsible for job submission, queue
management, resource allocation, and job execution. This service communicates with the Node
Manager service that runs on all compute nodes.
K
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.
Most runtime administration tasks are performed by using a remote login from a client.
M
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.
N
Network Each node has at least two integrated network interface cards (NICs). One NIC might be
Interface Card dedicated to the server's console. These NICs are used for connections to the internal networks.
(NIC)
Node-Level In federated clusters, an interconnect that has connections to nodes.
Interconnect
(NLI)
O
Onboard The enclosure management hardware, software, and firmware that is used to support all of the
Administrator managed devices contained within the enclosure.
(OA)
P
PXE Preboot Execution Environment
R
Remote RIS allows PXE BIOS-enabled computers to remotely execute boot environment variables.
Installation
Services (RIS)
T
Top-Level In federated clusters, an interconnect that provides links to other interconnects, multiplying
Interconnect (TLI) the number of possible pathways between nodes to create a full bandwidth fat tree topology.
Topology The organization of a network. HP Cluster Platforms contain networks based on flat tree and
fat tree topologies.
