15. What is Crowbar?
Mission: “A Zero Touch Cloud Installer”
Servers in boxes to full function cloud in under 2 hours
Fast & Flexible
Bare metal install including BIOS & RAID config
Users can choose how their system is configured (“barclamps”)
DevOps Embracing
Ongoing Operations Model (DevOps for Clouds)
Leverages & Wraps Opscode Chef

16. Crowbar Stages of Deployment
APIs, User Access,
Includes all the components required to implement
& Ecosystem an entire cloud infrastructure including ecosystems
Partners partners
Ops Management
Pluggable components deploy cloud infrastructure.
Dell “Crowbar”
Cloud
Allow for addition of Dell IP and expansion by the
Infrastructure &
Dell IP Extensions community services and customers
Can integrate with Dell existing products
Core Components & Delivers basic data center services and required
Operating Systems cloud infrastructure.
Provision bare-metal servers from box to cloud
WITHOUT user intervention (other than
Physical Resources racking/cabling and some minimal configuration
questions) NOT EXCLUSIVE TO DELL HARDWARE
