Op 1 april (geen grapje) opende Google zijn deuren tijdens de Google Data Center Efficiency Summit.
De sessies gaven een kijkje in de keuken met wat interessante innovaties:
– Google container (Zie datacenterknowledge artikel 1 & cnet )
Containers Based Data Center
· Speaker: Jimmy Clidaras
· 45 containers (222KW each/max is 250Kw – 780W/sq ft)
· Showed pictures of containerized data centers
· 300×250’ of container hanger
· 10MW facility
· Water side economizer
· Chiller bybass
o Limit chiller hours via raised temp inside
· High efficiency transformers: 99.5%
· 27C (81F) cold aisle
· Distributed UPS (each server has a lead accede battery).
– Google server design (Zie cnet & datacenterknowlegde artikel 2)
99.9% UPS Efficiency
o Distributed on-board UPS
o Single voltage motherboard (12v)
o Motherboard provides 5v to disk and all step downs needed by on board requirements
o Installed a lead-acid distributed UPS to ride through power sags
o Avoids double conversion of many central UPS
o Only enough power in UPS to allow generators to start or to switch to other A/C supply
