1. A data center comprising:
- a first set of data center units (DCUs);
a second set of DCUs coupled to the first set of DCUs via an internal network of one or more optical communication links;
wherein each DCU comprises a plurality of data processing units communicatively coupled by use of respective intra-DCU communication networks, each data processing unit comprising a plurality of servers and wherein the data processing units of the DCUs are configured to run a part or all of a data processing application;
wherein each DCU further comprises an optical interface unit configured to communicatively couple the respective intra-DCU networks to the internal network of optical communication links;
wherein the internal network comprises at least a first network hub and a second network hub; and
wherein the first and second set of DCUs are linked to the first and second network hubs, respectively, via one or more free space optical communication links.

Abstract
A data center for executing a data processing application includes processing units, sub-units or servers. Each of the processing units, sub-units or servers can execute a part or all of the data processing application. The processing units, sub-units or servers are electrical disjoint with respect to data communications, but can communicate with each other over free space optical links.

24. A method comprising:
-
providing a first set of data center units (DCUs); and providing a second set of DCUs coupled to the first set of DCUs via an internal network of one or more optical communication links, wherein each DCU comprises a plurality of data processing units communicatively coupled by use of respective intra-DCU communication networks, each data processing unit comprising a plurality of servers and wherein the data processing units of the DCUs are configured to run a part or all of a data processing application; concentrating a plurality of free space optical communication signals of the first set of DCUs into a composite signal at a first hub of the internal network; and directing respective free space optical signals of the composite signal to selected DCUs in the second set of DCUs at a second hub of the internal network. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
