Practical Considerations for Implementing Prefabricated Data Centers
•
1 recomendación•1,857 vistas
Implementing prefabricated modular data centers has benefits like speed of deployment and predictability, but the process is different than traditional data centers. Some key differences in the process are that prefabricated data centers use system-level design instead of component design, have simplified site preparation since much work is done in the factory, and modules can be transported and installed more quickly than constructing systems on site. The practical considerations discussed in the document provide guidance for planning, permitting, procuring, and installing prefabricated modular data centers.

- 2. Implementing prefabricated modular data centers results in well- understood benefits including speed of deployment, predictability, scalability, and lifecycle cost. The process of deploying them – from designing the data center, to preparing the site, to procuring the equipment to installation is quite different than that of athe equipment, to installation – is quite different than that of a traditional data center. This paper presents practical considerations, guidance, and results that a data center manager should expect from such a deploymentshould expect from such a deployment.

Introduction Understand practical considerations of deploying prefabricated mod lar data centersprefabricated modular data centers Considerations • Project plan and design• Project plan and design • Site prep • How equipment is procured • How equipment is installed and commissioned Schneider Electric – Data Center Science Center WP 166 Presentation – July 2014
- 4. Prefab vs. Traditional Data Centers Deployment process Prefabricated data center deployment Traditionaldata center deployment • Engineeringand specification performed at • Engineeringand specification performed at Plan / Design system level • Less than 12 weeks for planning/design component level • Generally 24 (or more) weeks for planning/design • Value of UL Listedor other agency listed modules omitted from permittingcosts • Permittingcosts include value of all systems • Permittingdocumentation requires detailed Sitepreparation • Permittingdocumentation focus on interconnections of modules • Inspection of field-work only, not of subsystems within modules • Options of indoor or outdoor placement Permittingdocumentation requires detailed drawings at subsystem level • Inspection of all field work, including traditional subsystem interconnections • Systems placed indoors except heat rejection and generatorOptions of indoor or outdoor placement • Modules generally placed directly over underground wiring/piping and generator • Wiring/piping to buildingmay require support hardware or special structures Procurement • Modules generally designedto meet transportation weightlimits, arrive near fully assembled • Products arrive in different shipments, by different vendors assembled • Construction trash is minimal • Construction trash is significant Installation • Climateand outdoor conditions / landscape impact placement/ orientation when installedoutdoors • Only outdoor cooling system and generator must consider outdoor conditions / landscape • Installedby forklifts and by hand, as separate Schneider Electric – Data Center Science Center WP 166 Presentation – July 2014 • Typically installedby truck crane products
- 5. Planning & Design Considerations Classification as “personal property” Prefab modules classified as “personal property” rather than “site” or “building improvements” • Modules booked and depreciated separate from building • May be leased independent of other site assets • May be moved from one regional data center to another whiley g maintaining its prior depreciation and value Schneider Electric – Data Center Science Center WP 166 Presentation – July 2014
- 6. Planning & Design Considerations System-level design engineering • Uses a system-level design approach rather than designing from partsg g p • No need for architectural decisions • Reduces time spent understanding• Reduces time spent understanding requirements and developing design • All components and controls implemented and tested in factory as a complete system Schneider Electric – Data Center Science Center WP 166 Presentation – July 2014
- 7. Site Preparation Considerations Site prep work is simplified • Permits obtained • Pipes and circuits laidPipes and circuits laid • Land/building readied for system • Site inspection Schneider Electric – Data Center Science Center WP 166 Presentation – July 2014
- 8. Site Preparation Considerations Permits and inspection • Reduced time to develop construction drawings and permit setsp • More efficient review and inspection • Inspection focused on field-constructed aspects of prefab data centers onlyprefab data centers only • Permitting costs don’t include value of facility module Schneider Electric – Data Center Science Center WP 166 Presentation – July 2014
- 9. Site Preparation Considerations Locating modules indoors vs. outdoors • Weather-tight modules designed for outdoor use • Saves money – outdoor square footage less expensiveSaves money outdoor square footage less expensive • Must be near utilities, i.e., electricity, water, etc. • Consider ease of installation, servicing and general housekeeping M d l i t ll d i d if• Modules installed indoors if: • module is skid-mounted • module enclosure is not weather rated • need/desire to protect personnel from inclement weather during operation and maintenance activities • require added security of critical systems Schneider Electric – Data Center Science Center WP 166 Presentation – July 2014
- 10. Site Preparation Considerations Foundations for modules • Continuous concrete slab • most commonmost common • Multiple independent concrete slabs • frequently used where surface waterfrequently used where surface water drainage is an issue • Piers or concrete columns • module is skid-mounted Schneider Electric – Data Center Science Center WP 166 Presentation – July 2014
- 11. Site Preparation Considerations Underground wire and piping interconnections • Data center module power less complex, less expensive if run undergroundp g • Requires fewer support structures • Can use less expensive materials • Power facility module can be dropped over pre-Power facility module can be dropped over pre installed underground electrical conduits • Simplifies weather sealing and conductor terminations • Cooling modules located adjacent to emergence of underground chilled water piping • Simplifies or eliminates need for support hardware Schneider Electric – Data Center Science Center WP 166 Presentation – July 2014 p pp or special structures
- 12. Procurement Considerations Simpler, faster than traditional data center • Modules purchased from single vendor as single system or set of systemsy • Delivery challenges avoided • Transportation regulations taken into account by prefab integrators Schneider Electric – Data Center Science Center WP 166 Presentation – July 2014
- 13. Procurement Considerations Transportation • Modules transported by truck • regulations governing weights andregulations governing weights and dimensions vary by state, country • ISO containers a common form factor • Module transport often contracted outModule transport often contracted out • Protective measures taken prior to shipment • examples – doors secured loose• examples – doors secured, loose items tied down Schneider Electric – Data Center Science Center WP 166 Presentation – July 2014
