Here are my notes from his talk:
- Microsoft challenges: 15x growth on servers, 9x growth on egress, 15x growth on power, 3x growth on number of data centers.
- 30% of the audience had active programs to monitor and measure power in their data center
- Next to nobody in the audience knew what their carbon emissions were for their data center
- Sustainability regulation 'is' coming ; not if, but when
- How many are working on green programs? 30% (audience)
- Industry challenges/minefields:
- sustainability reporting & efficiency reporting
- data center inventory globally becoming a challenge
- increasing power densities at the rack level
- power costs
- green-washing
- expertise shortage
- organizational structures
- increasing capital cost barriers
- innovation hoarding
- heterogeneity versus homogeneity mindsets.
- The 'old' power draw was 4kW / rack ; now is 8-12 kW / rack ; some implementations 36kW / rack
- $11-$18mil for a tier2 / tier2+ data center
- Cost of a data center:
- 82% construction costs : mechanical/electrical
- land: 2%, core&shell cost 9%, architectural: 7%
- 40,000 to 80,000 systems inside a typical 500,000 sq ft data center
- Staffing at a Microsoft data center: 35 people across 24x7x365 shifts.
- Boarding process: trucks pull up with pre-populated racks, drive into colo room, connect and go
- Driving automation is key ; have to have good operational practices.
- 35 factors for site selection. Including: Internet population, Internet peering/network, mobile users, power pricing, power capacity, environmental, construction costs, tax climate, IT labor availability, corporate citizenship -- this gives them their composite heat map. Quincy wasn't necessarily an ideal site until they went to the county level on a second pass and determined its benefits.
- Metrics: PUE vs DCIE : Microsoft uses both ; dcie shows the overhead ; goal, for either is ONE
- Microsoft sets aggressive pue targets internally.; they try to half the distance to a PUE goal by one every two years.
- Scribe (their software tool) ; shows/measures PUE, DCIE, total racks, total servers, kW power consumed, critical load power, etc.
- They have 1 million points to monitor/measure across data centers
- They have been measuring PUE for 4+ years ; an old data center of theirs started at 2.4 PUE and is at 1.9'ish in aug. 2007 ; very little if any capital improvements in this data center -- all driven by operational efficiencies.
- Chicago - their FIRST container data center!
- Entire first floor is full of containers ; each container houses 1,000 to 2,000 systems per container ; 150 - 220 containers on the first floor
- Containers are parked at 45 degree angle ; due to trucks parking them
- They build 'spines' of systems that connect power/cooling/bandwidth to their containers
