Two types of cabinets contain the HP XC system hardware:
Cabinets are used as a packaging medium. The application cabinets are optimized to meet power, heat and density requirements. The utility cabinet is intended to fill a more flexible need.
Because any node can be network capable, the only distinction of nodes in the utility cabinet is more disk I/O capability. The only strict rule is that the head node must be located in the utility cabinet and must be connected to the Root Administration Switch; see “Root Administration Switch ” for more information.
In all configurations, at a minimum, the utility cabinet contains the head node. Nodes with external storage should also be contained in the utility cabinet.
All nodes in the utility cabinet are connected to the root switches (administration and console). All nodes in an application cabinet are connected to the local branch switch.
