My Job: White Papers New Job Title: Equinix Co-Founder & Chief Technical Liaison Document Internet Operations Research • “Interconnection Strategies for ISPs” • “Internet Service Providers and Peering” • “Peering Case Studies” • “Peering Simulation Game” • “Build vs. Buy Internet Datacenter” today
White Paper: Interconnection Strategies for ISPs • Direct circuits replaced with: • OC-12 into Exchange • Fiber cross connects • Cost Drivers: • Big OC-12 Direct Circuit • Cheap Fiber Cross Connects • Aggregation Efficiency over OC-12 (2:1,3:1) • Rack Fees • Exchange Model Cost Formula: ExchangeModelCost=BigDirectCircuit()+(n-1)*x/2+RackFees() OC-12 $23,000/mo XC=$200/mo Rack=$1500/mo So does the Exchange-based model make sense?
Peering Peering Transit $$ WestNet USNet EastNet ISP A Transit ISP Routing Table ISP B Transit $$ White Paper: Internet Service Providers & Peering
White Paper: Build Vs. Buy Internet DataCenter • Modeling: • When does it make sense to build your own? • To Outsource? • Issues to consider • Economies of Scale? • Multiple Business Models
Service Level Agreements in Principle • Guarantee a higher level quality • Define Measurement Criteria for adhering to higher quality service Level • Meeting Performance Level critical to success of business • Failure to meet Service Levels penalty significantly worse than cost of service • eBay: $64,000/minute of downtime
SLAs in Practice • No SLA Pricing • ISPPriceNO SLA=X • SLA Pricing • ProbabilityOfMissingSLA=p • ISPPriceSLA1=X*(1+p) • Network does not typically change to meet new criteria • CIO Security Audit Story • Equinix Switch SLA: 99.999% Uptime
SLA-Datacenters • State-of-the-art Datacenters • Infrastructure Failure unlikely • SLAs rare, but… • Typically Limited to free month service • (Insufficient to potential loss customer faces) • But what is an Internet Datacenter? • Include hosting? Include Internet Service? Include Caching, Content Distribution? • Models help Define and Frame the Problem…
SLA Datacenter Parameters • If there were Internet Datacenter SLAs • Parameters: • Installation Lead Time • Service Availability • 24/7 Customer Support • Provisioning/Responsiveness • Independent of Transport and Internet Service Issues.
Creating the Build vs. Buy Internet Datacenter Whitepaper • Create a community white paper on issues associated with the building & scaling of Internet Datacenters • Identify the issues that folks should consider when making the build vs. buy decision Today: • Demonstrate the document & models to date and get feedback NOTE WELL: • EARLY STAGE OF BVB WHITE PAPER (v0.4)! • This Model may be of help to you in your SLA Discussions

Size Ultimate Goal Unit cost • Build Financial models that allow an ISP to say: • “Given our size requirements, it makes sense to build our own.” Or • “Given our size requirements, it probably makes sense to outsource this to someone who can realize economies of scale.” + + = Buy Build
Place to put stuff Proximity to Fiber Space Size Utility Power Facilities Yard Flavor of the Real Estate Model Data Center Operations Core Infrastructure Real Estate Scaling of Datacenter Real Estate? Increased Value Relationship
Scaling of the Real Estate Model $/sq. ft. Premium Real Estate Market (Tokyo, NYC,…) Real Estate Market (everywhere else) # Sq. Ft.
Real Estate Size is Important • Choose Too Small: Run out of space, lose economies of scale • Choose Too Big: Cost per Rack very high Vs. • Right of First Refusal (some Internet Datacenters allow this) • Expandability of Space
Commitment to DataCenter • 1 yr contract Vs. • 10 year lease Time to Market Issue – 6 – 9 months to build
Hidden Charges • Meet Me Rooms • Required products: • Must buy port on switch or certain volume of BW • Cross Connect Fees
Size & Finding Real Estate • 100,000 sq ft in downtown DC? • 10,000 sq ft in downtown DC • Vs. • Fiber Miles to Internet Datacenter

Heating, Venting, Air Conditioning (HVAC) Infrastructure • Controlled Humidity ~45% • Too much Humidity: System Failure • Too Little Humidity: Static Electricity • Air Temperature:~72 (IBM: 65-85) • Solutions: • DX Systems • Air Cooled • Water-Based • How do these Scale?
HVAC System Cost: Economies of Scale HVAC Cost HVAC Scaling Direct Expansion $1,000/ton Air Cooled $478/ton Chilled Water System $250/ton DX Systems: 25-300 tons of Cooling ~ 10K sq ft or ~150-200 racks # Racks Terramark Outsource of HVAC to FPL…

Security Infrastructure • 24x7 Manned • Access: Biometrics, card keys • Video Surveillance Sliding Glass
Power Infrastructure • Sun Netra 1U=90Watts • 40U Rack=3600 Watts! • Power Source • Power Grid (dual feeds) • Co-Generation • UPS/CPS/Generators • Energy Storage • UPS Batteries • Flywheel (no UPS) • Fuel Cells (service) • Monitoring Issues • Redundancy Issues • TBD: Scaling Issues
Fire Suppression Infrastructure • Two Dominant Systems: • VESPA air sampling • Dry pipe, pre action water system vs. FM-200 • Smoke & Heat Required to activate region
