Virtual Machine Mobility
LiveMigrationFaster, unrestricted, simultaneous VM live migrations between cluster nodes with no downtime. Now with Compression & RDMA support.
Live StorageMigrationMove the virtual hard disks of running virtual machines to a different storage location with no downtime
Shared-Nothing Live MigrationMove Virtual Machines between Hyper-V hosts with nothing but a network cable
Network Virtualization
• 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

Extended Replication
Replication configured from primary to secondary
DR Site
DASStorage
Replication can be enabled on the 1st replica to a 3rd site
Replication
• Once a VM has been successfully replicated to the replica site, replicacan 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
