ADC0063 – How KMD Designedits Virtual Infrastructure for aHigh-Availability EnvironmentAlan MadsenKMD, System Engineer
AgendaA little historyThe problem!3 Æ 1 datacenterIn sourcing of costumersThe solution!VMwareAssessment Storage Network VirtualCenterITIL in a virtual environmentWho will pay?
A Little HistoryStarted in 1972!3,000 employees2,8 billions revenueCore BusinessLocal authorityCentral governmentPrivate sector Outsourcing
The Problem!Strategic decision to consolidating 3 Æ 1 datacenter
The Problem!Denmark in Europe
The Problem!In-sourced customersHow to administer the customers Individual needs Individual SLA Auto failover, between datacenters Start working on issue within 15 minutes Low priority servers Individual configurationsHow do we administer that?
The Solution!The solution!VMware (surprise) - looked at Microsoft VirtualServerAssessmentDesign Storage Network VirtualCenterITIL in a virtual environmentWho will pay?
VMwareCreated a cookbook for virtualization in KMDBest practice for KMDVirtualizations standards for KMDScoreboard - ESX vs. MS Virtual Server (No match!)P2V tool
