A New Language for Specifying Modular Data Centers

  1. 1. A New Language forSpecifying Modular Data CentersNeil RasmussenSr. Vice President, InnovationAPC by Schneider Electric
  2. 2. Desired characteristics ● Flexibility ● Scalability ● Handles uncertain growth plans ● Quick to deploy ● Cost effectiveness ● Right-sized ● Low energy costs ● Simplified planning and engineering ● Predictable ● Performance clearly established in advance ● Tested and validated designs 2
  3. 3. Desired characteristics ● Flexibility ● Scalability ● Handles uncertain growth plans ● Quick to deploy Scalability ● Cost effectiveness ● Right-sized ● Low energy costs Standardization ● Simplified planning and engineering ● Predictable ● Performance clearly established in advance ● Tested and validated designs Standardization and Scalability are the key. Modularity is just a technical tool that can help us achieve these. 3
  4. 4. Modularity is valuable only tothe extent that it helps achievestandardization and scalability 4
  5. 5. Modularity is valuable only to the extent that it helps achieve standardization and scalabilityUnique Modular Designs Modular but not inherently scalable Designs 5
  6. 6. What is a modular architecture?● It defines a set of modules from which data centers are deployed● The set of modules includes the necessary and sufficient subsystems to create the data center● Subsystems are packaged together to in order to minimize complexity of deployment.● It is comprised of rules, tools, and methods that together prescribe how modules are deployed over time to support the growth plan for the data center● The compatibility and system performance of prescribed combinations of modules are assured in advance 6
  7. 7. What makes a modular architecture better?● The system is engineered to minimize the planning, installation, configuration, and programming work required to deploy IT capacity.● The “granularity” of module sizes has been established to be an effective tradeoff between cost, simplicity, and rightsizing for the application● It achieves better performance for the application (smaller, lower PUE, lower water use, lower failure rate, etc)● It allows for future options related to availability (redundancy) and power density● It is open enough to accommodate new modules from multiple vendors 7
  8. 8. Data Center Sub-systems to be packaged in a modular architecture Generators IT Racks Chilled Water Pumps Heat Exchanger Stationary PDUsFire Suppression Rack PDUs Cooling Towers Condenser Water Pumps Busway Switchgear CRAC Surveillance Humidifiers Air Handers UPS IT Racks Aisle Containment Lighting DCIM Software 8
  9. 9. Three characteristics needed to describemodular architecture How modularity is Modularity types implemented in devices to achieve functions Level of the system where Modularity hierarchy modularity is applied Relationship between Modularity linkages deployment of different modules Alternative modular architectures can vary in all three of these dimensions 9
  10. 10. Modularity Types how implemented in devicesDevice modularity: devices are made up of modularcomponents Examples: a large UPS frame that holds UPS modules a large air handler containing fan modulesSubsystem modularity: a functional block is made up of multiple devices of the same type Examples: a parallel array of UPS a parallel array of independent air handlers The function can be obtained by either or a mix of types. Subsystems (power, cooling, etc) can use different types 10
  11. 11. Modularity Hierarchy Level of system where implemented Data Center facility, comprised one or more units of IT Rooms, comprised of one or more units of IT Pods, comprised of one or more units of IT Cabinets Example: Modular air handler or UPS could be deployed at either the facility, IT room, IT Pod, or Rack level Modularity of different subsystems can be applied at different levels 11
  12. 12. Modularity Linkages Relationship between deployment of different modules Packaged linkage: devices of different subsystems are packaged together and must be deployed as a unit Examples: an IT pod module (or container) that contains a fixed group of racks, air handlers, PDUs, and environmental monitoring devices as a set Rules based linkage: rules establish allowed combinations of modules Examples: For 3 UPS modules a generator module must be deployed Granularity of deployment may be different for different subsystems, but relationship is defined 12
  13. 13. Communicating an architecture ● Graphical means to show all three modularity attributes together ● Modularity Type ● Modularity Hierarchy ● Modularity Linkages ● Shows how all key subsystems are deployed ● Illustrates rules of when modules are deployed ● Allows comparison of different modular architectures for ● Scalability ● Implementation of redundancy ● Investment required vs capacity 13
  14. 14. Pod Room Facility Enclosure Rack PDU deployed at Stationary PDU UPS Pod CRAH Subsystems Hot aisle containment Cooling Distribution Unit Humidifier deployed at CW loop pump Room Lighting Chiller Economizer Heat Exchanger750KW Tower deployed at3 rooms Facility9 pods Generator90 racks Switchgear8kW/rack80kW/pod Growth > 14
  15. 15. Four basic forms of modular power and cooling plants Plant provides power and1 cooling fluid to liquid cooled IT pods in rooms Plant provides power and2 chilled air to air cooled IT pods in rooms3 Plant provides power and cooling fluid to IT containers Plant provides power and4 chilled air to IT containers Note: All systems designed for IT loads using hot aisle containment 15
  16. 16. Magic numbers affecting modularity● 2.25MW: The maximum size generator set that ships on roadways without special permits● 8 x 8 x 40 ft: The size of an ISO shipping container● 800KW: The maximum transformer size that does not require supplemental downstream leakage current detection systems● 3000A: The maximum current rating of switchgear before the design must change to a larger and more expensive system● 14kW: The maximum size of a 415/240V rack PDU that does not require integral branch circuit breakers● 10,000 Amps: The maximum fault current of a power bus supplied to an IT space● 89 degrees F: maximum temp an IT operator can be continuously exposed to Data centers are likely to to drive modules toward optimal Numbers like these tend become a target for restrictions whereand interfaces that should become standards sizes water resources are scarce 16
  17. 17. Benefits when modules are standardizedand scalable ● Allows standardization of DCIM software ● Simplification of design process ● Rightsizing ● Speed of deployment / commissioning ● Pre-characterized performance ● Pre-fabrication ● Higher efficiency ● Add capacity with less disruption ● Mixing of types of modules (density, redundancy) ● Simplified maintenance programs ● Lower initial and lifecycle cost 17
  18. 18. Benefits when modules are standardizedand scalable ● Allows standardization of DCIM software ($0.4 - $1.5 per W) ● Simplification of design process ($0.1 - $0.3 per W) ● Rightsizing ($0.5 - $2.0 per W) ● Speed of deployment / commissioning ($0.1 - $0.2 per W) ● Pre-characterized performance ● Pre-fabrication ($0.2 - $0.5 per W) ● Higher efficiency ($0.5 - $2.0 per W) ● Add capacity with less disruption ● Mixing of types of modules (density, redundancy) ● Simplified maintenance programs ($0.2 - $0.5 per W) ● Lower initial and lifecycle cost* ($2.0 - $7.0 per W) *Savings from a typical lifecycle cost of $15-$25 per watt 18
  19. 19. Modular approaches are well suited forretrofits; drop in with less disturbance 19
  20. 20. Downsides of standardized modularity ● Customers may need to abandon certain preferences and internal standards ● Customers cannot choose an arbitrary final or step size, because capacity may only be available in certain size increments ● Some building shells or sites may be poorly suited or incompatible with available modules (ceiling height, room shape, accessways, etc) ● Unless standards emerge, customers choosing one architecture may feel “locked in” and find it difficult to move to alternative vendors for future expansion 20
  21. 21. The Future of Modularity ● Subsystems eventually packaged into three modules : ● Power plant ● Cooling plant ● IT space ● Differing needs will require different modular architectures: ● Size increments ● redundancy ● climate ● retrofits ● Industry standards for module interfaces need to emerge ● A common language for specification of modular data centers will emerge 21
