EXPANDABLE DATA CENTER WITH MOVABLE WALL

BACKGROUND

Organizations such as on-line retailers, Internet service providers, search providers, financial institutions, universities, and other computing-intensive organizations often conduct computer operations from large scale computing facilities. Such computing facilities house and accommodate a large amount of server, network, and computer equipment to process, store, and exchange data as needed to carry out an organization's operations. Typically, a computer room of a computing facility includes many server racks. Each server rack, in turn, includes many servers and associated computer equipment.

Because a computing facility may contain a large number of servers, a large amount of electrical power may be required to operate the facility. In addition, the electrical power is distributed to a large number of locations spread throughout the computer room (e.g., many racks spaced from one another, and many servers in each rack). Usually, a facility receives a power feed at a relatively high voltage. This power feed is stepped down to a lower voltage (e.g., 110V). A network of cabling, bus bars, power connectors, and power distribution units, is used to deliver the power at the lower voltage to numerous specific components in the facility.

Computer systems typically include a number of components that generate waste heat. Such components include printed circuit boards, mass storage devices, power supplies, and processors. For example, some computers with multiple processors may generate 250 watts of waste heat. Some known computer systems include a plurality of such larger, multiple-processor computers that are configured into rack-mounted components, and then are subsequently positioned within a racking system. Some known racking systems include 40 such rack-mounted components and such racking systems will therefore generate as much as 10 kilowatts of waste heat. Moreover, some known data centers include a plurality of such racking systems. Some known data centers include methods and apparatus that facilitate waste heat removal from a plurality of racking systems, typically by circulating air through one or more of the rack systems.

Many data center includes numerous rack-mounted servers housed in a building, which provides protection operating equipment. Such buildings may require a substantial investment in the form of construction costs, maintenance costs, and/or leasing costs. In addition, substantial time and resources are typically required to design and build a data center (or expansion thereof), lay cables, install racks and cooling systems. Additional time and resources are typically needed to conduct inspections and obtain certifications and approvals, such as for electrical and HVAC systems.

Many data centers rely on forced air systems and air conditioning to maintain the temperatures and other environmental conditions in the data center within acceptable limits. The initial and ongoing costs of installing and operating these systems may add substantial cost and complexity to data center operations.

The amount of computing capacity needed for any given data center may change rapidly as business needs dictate. Most often, there is a need for increased computing capacity at a location. Initially providing computing capacity in a data center, or expanding the existing capacity of a data center (in the form of additional servers, for example), is resource-intensive and may take many months to effect.

In some embodiments, fasteners, such screws, bolts, or clips, are used to secure modular side panels 232 and modular ceiling panels 234 on raised rails 224.

Rack computing systems 238 may be operated in computing room 242. Computing room 242 may be enclosed by modular panels 226, interior wall 228, and floor 222.

Data center 220 includes data center infrastructure modules 240. Data center infrastructure modules 240 and 241 may be coupled to any or all of modular panels 226. Each combination of a data center infrastructure module 240 and modular side panel 226 may serve as a side module. Data center infrastructure modules 240 may provide infrastructure resources, such as electrical power, cooling air, network connections, and storage, for compute resources in computing room 242. Data center infrastructure module 241 may include a hallway that spans between computing room 242 and another computing room in data center 220. Data center infrastructure modules 240 may be similar to data center infrastructure modules 140 described above relative to FIGS. 1A-1C. Thus, data center infrastructure modules 240 may include, for example, mechanical modules, network modules, secure storage modules, office space modules, and secure payment modules.

Rollers or sliders may be provided along the sides or on top of the interior wall or exterior to allow the wall to be carried on the structural elements.

In some embodiments, a movable wall is used in combination with modular panels to enclose a computing room of a data center. FIG. 7 illustrates one embodiment of a data center in which a movable wall has been positioned to serve as an end wall of a computing room. In this example, interior wall 228 has been moved to enclose computing room 242.

In the example shown in FIG. 7, the portion of data center 220 outside of computing room 242 may be raw space that is not yet ready to support computing operations. In some cases, the raw space may be used for purposes other than computing, such as equipment storage.

Exterior wall 230 may remain spaced away from interior wall 228. In some embodiments, exterior wall 232 provides protection from outdoor environmental conditions, such as rain, in the portion of the data center outside computing room 242.

As the need arises, a computing room may be made larger or smaller by installing or removing modular panel and data infrastructure modules. In some embodiments, a movable wall is pulled away from existing panels to encompass an expansion zone for more compute resources. In some embodiments, modular panels or infrastructure modules, or both, are added to previously installed supporting structure elements. In certain embodiments, supporting structure elements are added on an as-needed basis in advance of expanding computing space. For example, in the data center shown in FIGS. 6 and 7, sections of floor 222 may be added by pouring additional sections of concrete slab. As another example, sections of floor rails 223, raised rails 224, or both may be added as needed. In certain embodiments, additional structural elements for a hanging wall, such as a side rails or overhead rails, are added to a data center to allow the movable wall to be moved out to increase the length of a computing room.

Canopy 330 may have a bellows-type construction. A portion of canopy 330 may cover computing room 332 (for example, section 330a). As additional room is needed to house computing resources, exterior movable wall 334 may be moved out (for example, rolled along rails 336).

In the example shown in FIG. 12, canopy 330 is provided in sections. Sections of canopy may be connected to one another by way of interface plates 331. Interface flanges may include a flange for bolting adjacent sections to on another. Additional sections of canopy may be expanded as the wall is moved out. For example, section 330b may be expanded to create an expansion zone under section 330b. Sections of canopy that are not yet needed may remain in a compressed state, such as section 330c.

Canopy 330 may be supported on guide wire 333. The opposing ends of guide wire 333 may be attached to opposing end walls in the data center. Each of interface plates 331 may be hung on guide wire 333. Guide wire 333 may support canopy 330. For example, guide wire 333 may inhibit sagging of canopy 330 between the opposing end walls of the data center. In some embodiments, canopy 330 is at least partially made out of cloth.

Although in the embodiment shown in FIG. 12, canopy 330 is supported on a guide wire, a cover for an enclosure may be supported by other elements, such as a beams, trusses, rods, joists, or a roof structure. In some embodiments, supporting elements for a cover are provided below the cover. For example, in an alternate embodiment, guide wire 333 may be strung below canopy 330.

Although in the data center shown in FIG. 12, an enclosure may, in other embodiments, include other types of expandable covers. For example, in one embodiment, an exterior enclosure includes a series of nested roof sections connected to movable exterior wall. As additional space is needed in a data center, the exterior movable wall may be moved out to use one or more additional roof sections.
