Damian Flynn MVP Cloud and Datacentre Ask Damo! Unravelling the network with SCVMM 2012 Level 200
Damian Flynn MVP Cloud and Datacentre • Systems Architect, Corporate IT Infrastructure, Lionbridge • MVP - Cloud and Datacentre Management
Objective “With the launch of Windows Server 2012 Hyper-V, Microsoft introduced to the world its solution for Software Defined Networks, enabling System Center Virtual Machine Manager 2012 SP1 as their management platform of choice.” In this webinar, we outline the concepts, benefits and steps you need to understand to embrace your own “Virtual Network”.
Unravelling the Network Focus Topics • Isolation Technologies • VLAN’s • Virtual Local Area Networks • PVLAN’s • Private Virtual Local Area Networks • SDN’s • Software Defined Networks / Virtual Networking • SCVMM • Logical Networks • VM Networks
Unravelling the Network Related Topics • System Center Virtual Machine Manager • Port Profiles • Uplink’s • Network Adaptor’s • Port Classifications • Virtual and Logical Switches • Virtual Network Interfaces • Converged Networks • TRY IT • Step-by-Step build out @ Tech-Ed North America 2013 • http://channel9.msdn.com/Events/TechEd/NorthAmerica/2013/MDC-B318
Windows Server 2012 Isolation via VLAN • Common solution • VLAN per tenant • Does NOT scale (only 4095 VLAN Limit) • Management complexity grows with scale Illustration – VLAN Scale Book - Hyper-V 2012 Configuration and Installation
Windows Server 2012 PVLAN’s • Isolation • All VMs isolated from each other • All VMs may have internet access • Perfect for 1 Off VMs • Community • Groups Tenant VMs together • Isolated from other tenants • All VMs may have internet access • Utilizes VLAN id per Community SCVMM 2012 SP1 NOT Feature COMPLETE Implement Using CISCO NEXUS 1000v Integration Illustration – PVLAN Relationships Book - Hyper-V 2012 Configuration and Installation
Network Virtualization Blue and Red • Network Virtualization • Run multiple virtual networks on a physical network • Each virtual network has the illusion that it is running physically
Network Virtualization Why??? • Any Service, Any Server, Any Cloud • Decouple tenants infrastructure from physical infrastructure • Policy based, Software defined networking • Segregation of Duties • Network administration decoupled, to focus on capacity and performance • VM placement possible, independent of network topology • Scalable Layer 3 Virtual Networking • Reduction of Complexity and Cost for Network infrastructure • Scalable design • New Industry Standard • Cisco and F5 publicly announced support for “NVGRE”
Network Virtualization Data Plane - VLAN’s

Network Virtualization Why???
Network Virtualization The Fact’s • Network Virtualization • Virtualize the VMs IP address!... • Each VM uses 2 IP addresses… • IP Address visible within the VM • Data Plane (Referred to as Customer Addresses (CA)) • May overlap between Customers • IP Address visible on the physical network • Control Plane (Referred to as Provider Addresses (PA)) • Addresses may be IPv4 or IPv6 • Control Plane is Normal TCP/IP – Protocol 47 GRE • Modified Header as Per RFC 2784 / 2890 • Existing Layer 2/3 Switch gear will pass traffic without issues

Network Virtualization Encapsulation • Bring Your Own Address • Encapsulate the VM IP address (CA) into the Hosts IP address (PA) • GRE permits a single Host IP Address to encapsulate all its VMs addresses • Tennant Identifier stored in the GRE packet to retain isolation
Network Virtualization In Action… • VM Movement • The Virtual Machine retains the VSID, MAC and its IP address • This Information migrates with the VM around the hosts • Hosts DO NOT need to be clustered! • Network Virtualization Extension • Does NOT track VM Movements • Lookup table must be MANUALLY updated • To Scale… Use Orchestration • Microsoft System Center Virtual Machine Manager 2012 SP1
