VM Mobility Shared Nothing Live Migration, Multiple Live Migrations, Storage Migration

Manage virtual machines independently from underlying infrastructure Handle changing needs on demand Live migration within a cluster Shared-nothing live migration Hyper ‑ V Replica Live migration of storage

Reads and writes go to the source VHD Reads and writes go to the source VHD. Live Migration Begins Disk contents are copied to new destination VHD Disk writes are mirrored; outstanding changes are replicated Live Migration ContinuesLive Migration Completes Destination Hyper ‑ V Virtual machine Target deviceSource device Virtual machine Source Hyper ‑ V IP connection Configuration data Memory content Modified memory pages Live Migration MEMORY VHD Increase flexibility of virtual machine placement Reduce downtime for migrations across cluster boundaries Increase administrator efficiency Benefits

Demo Shared Nothing Live Migration

Hyper-V Replica Business Continuity and Disaster Recovery

 Replication changes are sent every 5 minutes  Additional recovery points can be configured  Incremental VSS copy for Application consistency  IP Injection for Replica

Log File 2 Primary Host VHD Log File 1 Fixed Replication Frequency Log to VHD converter Driver APP X Primary VM VHD Replica VM Replica Host

 Place Page file on a separate VHDX  Network QOS for Replica Traffic  How to send Initial Replica?  Do I need more than one Replica listener?  Replica Folder name as GUIDs

Demo Hyper-V Replica

Network Network Teaming, QoS, SMB3

 Up to 32 Network Cards  Unlimited Virtual Interfaces (t-nics)  Hyper-V distribution mode available  Switch Independent and dependent Mode

 Use QoS to enable multi-tenancy and avoid overprovisioning in you datacenter  Minimum and Maximum Bandwidth options  Weight for Minimum Bandwidth allows oversubscription  DCB

 What if I only have 1 Gbit/s Nics?  What if I have two 10 Gbit/s Nics?
