• a first memory subsystem configured to identify and distribute resources of the first memory and to control data transmission of the first memory;
• a first processor unit comprising a first processor connected to the first memory subsystem;
• a second memory;
• a second memory subsystem configured to identify and distribute resources of the second memory and to control data transmission of the second memory;
• and
• a second processor unit comprising a second processor connected to the second memory subsystem,
• wherein the first processor unit communicates with the second processor unit via an Ethernet communication channel, and
• the first memory subsystem communicates with the second memory subsystem through a memory bus that is a data transmission channel separate from the Ethernet communication channel.
