A Little History
Started in 1972!3,000 employees2,8+ billions revenue Core Business
Local authorityCentral governmentPrivate sector• Outsourcing
The Problem!
Strategic decision to consolidating 3 1 datacenter
The Problem!
Denmark in Europe
The Problem!
In-sourced customers How to administer the customers• Individual needs• Individual SLA
• Auto failover, between datacenters• Start working on issue within 15 minutes• Low priority servers
• Individual configurations
How do we administer that?
The Solution!

VirtualCenter
VirtualCenterRunning in a Virtual Guest• Pros and consHA and DRS• Reflects KMDs Network infrastructure• Original design reflected storage configuration!Datacenter/folder creation• Access ControlResource Management• Why we “almost” don’t use it• Transparent page sharing! (a small hint)
VirtualCenter
Super admins VS. Admins vs. UsersProcess for keeping the servers up and running in a HA environment
Super admins (technology group)• Configuration and installing new ESX• Managing LUNs
Admins (department admins)• Creating new VMs
Users• Accessing VM´s (KVM access)
