1.1Supported Cluster Platforms

An HP XC system is made up of interconnected servers.

A typical HP XC hardware configuration (on systems other than Server Blade c-Class servers) contains from 5 to 512 nodes. To allow systems of a greater size, an HP XC system can be arranged into a large-scale configuration with up to 1,024 compute nodes (HP might consider larger systems as special cases).

HP Server Blade c-Class servers (hereafter called server blades) are perfectly suited to form HP XC systems. Physical characteristics make it possible to have many tightly interconnected nodes while at the same time reducing cabling requirements. Typically, server blades are used as compute nodes but they can also function as the head node and service nodes. The hardware and network configuration on an HP XC system with HP server blades differs from that of a traditional HP XC system, and those differences are described in this document.

You can install and configure HP XC System Software on the following platforms:

•HP Cluster Platform 3000 (CP3000)

•HP Cluster Platform 3000BL (CP3000BL) with HP c-Class server blades

•HP Cluster Platform 4000 (CP4000)

•HP Cluster Platform 4000BL (CP4000BL) with HP c-Class server blades

•HP Cluster Platform 6000 (CP6000).

•HP Cluster Platform 6000BL (CP6000BL) with HP c-Class server blades

For more information about the cluster platforms, see the documentation that was shipped with the hardware.
