Agenda

VM-MobilityHyper-V ReplicaNetworkingCross Platform Migration

VM Mobility

Shared Nothing Live Migration, Multiple Live Migrations, Storage Migration

Virtual Machine Mobility

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

Network Teaming, QoS, SMB3

Hyper-V Networking

Two physical network adapters at minimumOne for managementOne (or more) for VM

networkingDedicated NIC(s) for iSCSIConnect parent to back-end

management network Only expose guests to

internet traffic

Network Teaming (LBFO)

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

Mode

QoS Policies

Use QoS to enable multi-tenancy and avoid overprovisioning in you datacenter

Minimum and Maximum Bandwidth options

Weight for Minimum Bandwidth allows oversubscription

Cross Platform Migration

Virtual Machine Converter

Microsoft VM Converter

Converts and Deploys Virtual Machines from VMware hosts to Hyper-V

Converts the virtual disks Converts the memory, virtual processor configuration, adds network interface

Supports conversion of Virtual Machines from: VMware vSphere 4.1 (if managed by vCenter 4.1) VMware vSphere 4.1 VMware vSphere 5.0

Uninstalls VMware tools prior to conversion Creates Snapshot before uninstallation for easy fallback

Scriptable command-line interfaces Wizard-driven GUI
