DKK in Denmark (2011)■ Atea is in 7 countries across the Nordic and Baltic countries■ Supplier of IT infrastructure■ Hosted Infrastructure services■ Remote backup solutions■ Supplier of hosted services■ For small, medium and large companies in the privateand public sectors..■ More than 5,800 employees■ 1,500 in Denmark, spread over 6 locations
  • 4. 3Atea Datacenter & Cloud Services (ADC) Outsourcing– Responsible for the overall operation and maintenance of a companies ITinfrastructure. Includes Servicedesk, Netværk, Server, Storage, Changemanagement – based on ITIL framework Infrastructure as-a-Service – IAAS– A platform in a virtualized environment - as a service, including servers,network, storage and backup. Cloud Backup– Remote backup solutions
  • 5. 4ADC – Storage EnvironmentsOur Storage environment can be divided intotwo different categories : Outsourcing– (IAAS, VMware, SQL, Exchange osv.) Backup– (TSM & CommVault)All storage is based Enterprise, Midrange and Entry level from IBM
  • 6. 5IBM Storage systems - EnterpriseIBM Storage systems at AteaEnterprise level: 2 - DS8300 4 - DS8700 5 - SVC clusters – with 24 nodes
  • 7. 6IBM Storage systems - MidrangeIBM Storage systems at AteaMidrange: 7 - IBM V7000 and 1 - V7000 unified 4 - IBM DS5300 4 - DCS3700
  • 8. 7IBM Storage systems - Entry-levelIBM Storage systems at AteaEntry level: 2 - IBM V3700 3 - IBM DS3500
