Principal Engineer, Global Infrastructure & Strategy at
Data Center Philosophy
• Every element in the data center is a server
• Appliance free data centers
• Multi-Supplier for every component in the data centers
• Solve in software what you can
Scale OutFlash for storage Disaggregation Cost Optimized
The Open19 Project
Open19 Project Goals
• Create an open standard that can fit any 19” Rack environment
for server, storage, and networking
• Create a solution that will have applicability for large, medium,
and small scale data centers
RACK DEPLOYMENT COST OPTIMIZATION
Reduce commons by 50%
CONSOLIDATE REQUIREMENTS
Eco system with high adoption level
ENABLE FASTER RACK INTEGRATION
3-5x faster integration time
Open19 Project Non-Goals
• Create a proprietary form factor
Low adoption level
• Create restrictive development environment
Minimized defined specification
• Build a heavy bureaucratic organization
Minimal organization that will enable collaboration
Engineering focused first

Brick Cage
• Passive mechanical
cage
• 12RU and 8RU options
• 2RU modularity– 4x Bricks
– 2x Double High Half Width
– 2x Double wide
– 1x Double High
• Snap-on rear opening
Rack View:
Full Cable without Rack:
• Plastic ‘spine’ snaps
around main cable
breakout
Close-Up Cable
• 4X2 Impel breakouts remain
flexible
• Length of 4X2 Impel optimized so
that cable will sit closer to the
rack
Bricks Form Factors
• Four brick form factors
– Brick (½ wide 1RU)
– Double High Half Width – (2RU)
– Double Wide Brick (1RU)
– Double High Brick (2RU)
• Linear power and data growth
• Self Sustained – EMI & Safety
& cooling
• 100G Blind Mate network
Servers in design
• Dell, HPe, SuperMicro, Flex, Celestica and Inspur are actively
working on Open19 server
• White boxes in development by Linkedin:
• Quad socket Broadwell-DE in a half width 1RU (brick)
• Dual socket High-end Skylake with up to 1.5T memory in 1RU
• Storage Servers – Single socket up to 32 drives per 1RU
• One clarification about the high density solution – To get to the
full capacity (96 @ 19.2Kw) the core count will only be 3000
Open19 Switch
• 3.2T Switch
• Dual switch: Data Path &
Management (OOB)
– 50G per server data path
– 1G per server management (optional)
– Console port per server (optional)
• 12v input (no power supplies)
• Up to 8x100G uplinks or local
switching ports
• Broadwell-DE CPU with BMC
• Linkedin white box design
Open19 Power shelf
• Two configurations:• 1RU 9.6KW per leaf zone
• 2RU 19.2KW per leaf zone
• Shared power modules
• Management via GE port
• Full AC and DC range
• Multi-Source for the shelf and modules
• Per server protection and monitoring OPTIONAL BBU
Optional rack level battery
back unit
Fast Installation Process
• Any 19” Rack
• Install the cages: 4 screws each, front only
• Install the power shelf: 2 screws, front only
• Install the two switches: 2 screws each, front only
• Snap-on cables to the back of the cages: Tool-less
• Plug the power shelf: Snap-on cable, tool-less
• Connect the switch: Snap-on + optics, tool-less
• Blind-mate install the bricks: Tool-less
• Connect the power feed to the power shelf: Tool-less
• GO: The rack is integrated, up and running!
Platform Benefits
ANY19” RACK
Any location
DISAGGREGATION
Self sustained servers
EFFICIENT POWER
Single stage 96% power conversation
No server power supplies
LEVERAGE EXISTING SERVERS
Bricks form factor fit most existing motherboards
MULTI-SERVER TIERS
Four form factors
Server IP protection and innovation
FULLY REDUNDANT INFRA
A/B 2N power redundancy
No central controllers
COST EFFECTIVE
Rack level cost reduction
Solution cost savings
SHORT INTEGRATION TIME
5-6x faster rack level integration
Open19 Deployment Models
• Traditional: Data center operators
• Bare metal cloud service: Lease a slot - Emerging
• High efficiency offsite integration
• Edge platform cloud optimization
Future Developments for Open19
• Open orchestration & management software
• Different cage form factors
• New “server” models
• Automated data center deployment model
• Optical snap-on data cabling
• Liquide cooling integration
• Automated data center
• Any other “crazy idea”
Linkedin Deployment Model
Staged Datacenter Deployment – Stage1
Pre-Server Stage
• Build out to site/suite capacity of empty cages
• Power shelf and cables integration
• Switching integration with optical uplinks
• Move to warm deployment state
• Cost effective
• Accelerating date center deployments
Staged Datacenter Deployment – Stage2
Server Integration
• Insertion of servers on demand
• Fully automated provisioning and deployment
• Deploy 1000s of severs in days not months
• Create an elastic data center model with fix low cost infra
Staged Datacenter Deployment – Stage3
Sustaining & Operations
• Never touch infra
• Server only blind mate insertion removal
• Full monitoring and automation
