1. A computing unit comprising:
- a processing resource configured to perform a computing function;
a memory resource configured to store payload data; and
a wireless radio frequency (RF) communication element configured to;
form a directionally-focused wireless RF beam having a defined beam spread angle, the directionally-focused wireless RF beam being oriented in a fixed direction relative to the computing unit;
use the directionally-focused wireless RF beam to establish a connection with a second computing unit that is located within the defined beam spread angle of the directionally-focused wireless RF beam and communicate the payload data over the connection;
while the connection to the second computing unit remains established, detect that a third computing unit that is also within the defined beam spread angle of the directionally-focused wireless RF beam has sent an acknowledgement to a fourth computing unit in response to a connection request sent by the fourth computing unit; and
responsive to detecting the acknowledgement sent by the third computing unit to the fourth computing unit, send a disconnection message to the second computing unit.

Abstract
A data center includes a plurality of computing units that communicate with each other using wireless communication, such as high frequency RF wireless communication. The data center may organize the computing units into groups (e.g., racks). In one implementation, each group may form a three-dimensional structure, such as a column having a free-space region for accommodating intra-group communication among computing units. The data center can include a number of features to facilitate communication, including dual-use memory for handling computing and buffering tasks, failsafe routing mechanisms, provisions to address permanent interface and hidden terminal scenarios, etc.

4. A method comprising:
-
establishing a connection between a first computing unit and a second computing unit using a first directionally-focused radio frequency (RF) beam pointed in a fixed direction relative to the first computing unit, the second computing unit using a second directionally-focused RF beam to communicate over the connection with the first computing unit; while the connection between the first computing unit and the second computing unit remains established, detecting that a third computing unit has sent an acknowledgement to a fourth computing unit in response to a connection request sent from the fourth computing unit to the third computing unit, the first computing unit falling within a third directionally-focused RF beam used by the third computing unit to communicate the acknowledgement; and responsive to the detecting the acknowledgement sent by the third computing unit to the fourth computing unit, disconnecting the first computing unit from the second computing unit. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)

13. A system comprising:
-
a first computing unit configured to communicate using a first directionally-focused RF beam that is pointed in a first fixed direction relative to the first computing unit; a second computing unit configured to communicate using a second directionally-focused RF beam that is pointed in a second fixed direction relative to the second computing unit; a third computing unit configured to communicate using a third directionally-focused RF beam that is pointed in a third fixed direction relative to the third computing unit; and a fourth computing unit configured to communicate using a fourth directionally-focused RF beam that is pointed in a fourth fixed direction relative to the fourth computing unit, the first computing unit being configured to establish a connection with the second computing unit, the fourth computing unit being configured to send a connection request to the third computing unit, the third computing unit being configured to send an acknowledgement in response to the connection request sent by the fourth computing unit, the first computing unit being configured to, while the connection with the second computing unit is currently established; detect the acknowledgement sent by the third computing unit to the fourth computing unit; and terminate the connection with the second computing unit responsive to detecting the acknowledgement. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
