20. A server maintenance method for updating portions of servers within a datacenter that includes a power bus configured to supply power to a plurality of server racks arranged within a space of a building, a first power source connected to the power bus from a first side of the building and configured to supply power to the power bus, a second power source connected to the power bus from a second side of the building different from the first side and configured to supply power to the power bus, and a plurality of diverter switches arranged within the power bus, and one or more controllers connected to the plurality of diverter switches to redirect power within the power bus, the method comprising:
providing, from the one or more controllers, first control signals to the plurality of diverter switches to electrically disconnect a first portion of servers from the first and second power sources without disconnecting a second portion of servers from the first and second power sources;
conducting maintenance on the first portion of servers;
providing, from the one or more controllers, second control signals to the plurality of diverter switches to electrically reconnect the first portion of servers to the first and second power sources without disconnecting the second portion of servers from the first and second power sources;
providing, from the one or more controllers, third control signals to the plurality of diverter switches to electrically disconnect the second portion of servers from the first and second power sources without disconnecting the first portion of servers from the first and second power sources;
conducting maintenance on the second portion of servers;
providing, from the one or more controllers, fourth control signals to the plurality of diverter switches to electrically reconnect the second portion of servers to the first and second power sources without disconnecting the first portion of servers from the first and second power sources,
wherein the first portion of servers are collectively located at a first location of the building and the second portion of servers are collectively located at a second location of the building that is separate from the first location, and
wherein the first and second portions of servers are portioned according to respective levels of confidentiality.
