SGI - Overview

The “New SGI” On May 8th 2009, Rackable Systems acquired the Assets of Silicon Graphics Inc, and renamed the company – “SGI” Founded 1999 Leader in Internet & Cloud Specialisation – “Build to order + Founded 1981 Leader in High Performance Computing systems, Ecological, low-power Specialization – Shared Memory Systems, Scalable server solutions” HPC Clusters, Storage solutions Company Confidential 4

SGI’s Technology solutions Cluster Shared Storage Eco-Logical HPC Cloud Computing Memory Data Center Cloud Computing service for technical applications SaaS & IaaS models SGI H/W, SGI- certified S/W, SGI hosted, access to SGI experts Scale-Out Scale-Up Fast storage Power efficiency Software 8 to 1M+ cores 8 to .25M cores EBOD to RAID High density Custom designs Big memory Data Management Efficient cooling _______________ ________________ ________________ ________________ Cloud Computing Communications Scale-out active Backup & data Internet intensive HPC archives Recovery Performance packs Parallel HPC In-memory Streaming Data center Management tools databases applications expansion Industry std Linux Federal Mixed-use Mobile data government environments centers applications Company Confidential 5

Company Confidential “The Rackable Way” 6

The Expert in Scale-Out Datacenters Successful Deployments of 100K’s of Servers in single instance Over 1 Million servers sold to date “Scale-Out” requires new thinking: – Build-To-Order model… NOT “one-size-fit-all”. – Optimize Packaging: Server, Cabinet, container – Lowest power – Innovative cooling Company Confidential 7

“The Internet Runs on Rackable!” Company Confidential 8

Guiding Principles Focus on the data center Superior design and technology Company Confidential 9

Cloud Trends

Where is the Cloud Going? Greenpeace: Cloud Computing is growing fast It’s going Everywhere Trends of cloud-computing: – Growing usage – Growing datacenters – Growing electric demand – On the bright side – growing awareness to environment We can help!... The question is “How?” Company Confidential 11

How can we help reduce the impact? Electricity is used to Power Up the datacenter – Servers, Storage – Backup Power equipment – Cooling the infrastructure We can help by optimize and lowering (or eliminating) energy consumption in these aspects – Use more efficient compute and storage – Eliminate traditional power backup infrastructure – Use free air cooling, free water cooling Company Confidential 12

Why is Server Power so important? “The cost of operating a server for 3 years is higher then the cost of buying the server” A typical server: $2,000, 250 Watts Cost of power: $0.20 / KW-hour Cost of 3-year electric use: ~$1,314 If PUE = 2.0… power+cooling: ~ $2,628 If PUE = 1.1… power+cooling: ~ $1,445 Company Confidential 13

Innovation: short servers Reduces chassis length by 50% Air needs to move less distance – Less fans save power – Slower fans save power – Higher inlet air temperature save cooling save power Company Confidential 14

Typical Full-Depth Server - Cooling Design 25” / 63cm Long 2 fans 2 2 2 2 2 1 2 2 2 19 fans x 8w = Company Confidential 15 152 Watts

Rackable Eco-Logical™ Chassis Design 15.5” / 40cm Long 5 fans x 4.5w = 22.5 Watts Company Confidential 16

Chassis Design If we can save 100w per server with smarter fan and chassis design 1000 servers = ~ 100 kW difference Company Confidential 17

How Else Can We Reduce Power Draw? Use low power parts in the server Eliminate unnecessary components Use very efficient power supplies Match Power Supply to server load Cabinet-level power consolidation, monitoring, capping Optional DC-Power Company Confidential 18

Fans & Heatsinks Company Confidential 19

Popular High efficiency Servers Rackable 1U Server Rackable 3U Servers 22.5 watts fan draw! 13.5 watts fan draw! Rackable 2U Server 13.5 watts fan draw! Rackable 4U Server 13.5 watts fan draw! Company Confidential 20

Cabinets Density Density Sizes Options Sizes Options Half-depth server design mounted Choice of back-to-back for 2x density 22U, 36U, 40U, 44U Thermal Management Thermal Management & Power Distribution & Power Distribution Unobstructed central air plenum for superior ventilation DC Power option provides power savings of up to 30% Passive cooling design for highest reliability I/O in front and clean cabling reduces maintenance time by up to 75% IPMI or Roamer-Based remote management Serviceability Serviceability Company Confidential 21
