CPU box

Depending on the configuration, the CPU box contains one or two system boards.

Each system board contains a processor chip with the following features:

• depending on the model, up to eight CPU cores with a joint cache

• two IOPs (I/O processors)

• one Mac (Memory Access Controller)

• The processor chip is connected directly to the memory of the system board.

• Processors on different system boards communicate over an Inter Connect Interface.

The CPU box, together with AROMA-P, occupies six height units (HUs) in the rack.
