Compute Nodes; Hpc Networks - HP LC Series Setup And Installation Manual

Compute Nodes

Depending on which configuration was ordered, the cluster contains ProLiant DL140,
ProLiant DL145, or ProLiant DL360 server compute nodes. The compute nodes perform the
basic work unit of the cluster. More compute nodes are added to the cluster to increase
performance.
The current LC Series cluster reference designs scale to support up to 128 nodes per cluster.
The server models and options available for use in the cluster are listed in the Design and
Configuration Guide. In Myrinet solutions, each compute node will have a PCI Myrinet
adapter installed.

HPC Networks

Each HPC LC Series cluster includes multiple networks:
•
Out of Band Management network
The Out of Band Management network provides cluster management capability not
available via the In Band Management network.
Cyclades terminal servers are used for Out of Band Management on ProLiant
DL140 server based systems. HP ProCurve 2650 switches are used for Out of Band
Management on ProLiant DL145 server based systems using IPMI. ProCurve 2650
switches are used for Out of Band Management on DL360 server based systems using
iLO.
•
Cluster interconnect network
The cluster interconnect network is the main data network that connects all of the
compute nodes for cluster interprocessor communication (IPC) and message passing
interface (MPI) functions. This network can be either a Myrinet, Gigabit Ethernet, or
10/100 Fast Ethernet network.
Various types of ProCurve or Myrinet switches are used for the cluster interconnect
network, depending on the overall type and size of the HPC solution.
•
Management network (In Band Management)
The management network (In Band Management network) is used for overall cluster
management using a standard Ethernet connection. This network is also used to connect
storage systems to the cluster in the reference designs.
Gigabit Ethernet ProCurve 2848 or 10/100 Fast Ethernet ProCurve 2650 switches are
used for the management network, depending on the cluster configuration.
•
Public network
The control node connects the cluster to the public network (WAN interface).
