A server room, characterized by rows of computer server racks. On the left side, a tall server rack is prominently displayed. It is filled with multiple tiers of server units. To the right of the first rack, another server rack is partially visible, also filled with server units and drives. The arrangement suggests a highly organized and dense installation of computing hardware.
