Hyper-V er ute i 2012 R2-drakt og har blitt den perfekte byggestein for Hybrid Cloud. Men for de med lang fartstid på VMware kan veien virke lang. Kom og få en ærlig gjennomgang av Hyper-V og SCVMM med praktiske referanse til tilsvarende VMware teknologier. Ved Asbjørn Tonstad, Peanuts AS

12. • Secure Isolation for traffic segregation,
without VLANs
• VM migration flexibility & Seamless
Integration
Key Concepts
• Provider Address – Unique IP addresses
routable on physical network
• VM Networks – Boundary of isolation
between different sets of VMs
• Customer Address – VM Guest OS IP
addresses within the VM Networks
• Policy Table – maintains relationship
between different addresses & networks
Network Isolation & Flexibility
without VLAN Complexity

16. Replication configured from primary to secondaryReplication can be enabled on the 1st replica to a 3rd site
• Once a VM has been successfully
replicated to the replica site, replica
can be replicated to a 3rd location
• Chained Replication
• Extended Replica contents match the
original replication contents
• Extended Replica replication frequencies
can differ from original replica
• Useful for scenarios such as SMB ->
Service Provider -> Service Provider DR
Site
Replicate to 3rd Location for
Extra Level of Resiliency

23. Hva er ikke så bra?
 Virtual Machine Manager – Støtter ikke alle funksjonalitet
 Det er litt annerledes så regn på en transisjonskost
 V2V fra VMware til Hyper-V
