Networking Fabric in Hyper-V and VMM Richard Ulfvin

Who the heck are´ya!  Might know commands like ” sh run ” or ” sh config ”…  … might have tried tools like NetSH or Netmon …  … played with Hyper-V or just configured an IP address on a server 

Session Objectives And Takeaways  Objectives  Understand networking in Windows Server 2012  Understand the Hyper-V switch and its features/extensions  Understand what SDN is and Microsofts approach to it  Get to learn how Virtual Machine Manager can manage networks  Key Takeaways  When to use different features/extensions  How to get started

Who Am I – Where do I work

Why this session? We face many network challanges like…  Keep systems and services running  High to continous availability  High reliability and reduced complexity  Security, multitenancy, extensibility  Cannot keep throwing money at it (CAPEX)  Network virtualization, QoS, bandwidth management  Performance (latency, throughput, scalability)  Control Operational cost (OPEX) – Reduce complexity

Network bottlenecks …  In the host networking stack  In the NICs  In the switches

Network Features…  Receive Side Scaling (RSS)  Receive Segment Coalescing (RSC)  Dynamic Virtual Machine Queuing (DVMQ)  Single Root I/O Virtualization (SR-IOV)  NIC Teaming  RDMA/Multichannel support for virtual machines on SMB 3.0

…and more features.  DCTCP/DCB/QoS  DHCP Guard/Router Guard/ Port Mirroring  Port ACLs  IPSEC Task Offload for VMs  Network virtualization

DEMO A Look Inside Windows Server 2012

The Hyper-V Switch  Hyper-V Port ACLs & Switch Extentions.  Extensions are Filters or Windows Filtering Platform providers.  Extensions state / configuration is unique to each instance of an extensible switch on a machine Extension Extension Virtual Switch Extension Extension Virtual Switch Hyper-V Host 1 Hyper-V Host 2 Extension Extension Hyper-V Host 1 Hyper-V Host 2 Extension (Capture) Logical Switch (VMM) Extension (Filtering) Virtual Switch Extension Manager (VSEM) Extension (Forwarding)

Why network virtualization?
