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
