1 Networking Fabric in Hyper-V and VMM Richard Ulfvin

2 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

3 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

4 Who Am I – Where do I work Networks… WTF!!!

5 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

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

7 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

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

9 DEMO A Look Inside Windows Server 2012

10 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

11 DEMO A Look Inside the Hyper-V switch

12 Extensions in Hyper-V Switch  5Nine - http://www.5nine.com (WFP)  InMon - http://www.inmon.com (sFlow)  Cisco (Nexus 1000v)

13 Concept of networks in SCVMM Logical Network “Corp” Host group “Production” M - M IP Pool “StaticSrv” “10.0.0.1- 10.0.0.99” 1 - M Physical network adapter M - M 1 - M Virtual switch Virtual network adapter 1 - 1 1 - M Subnet- VLAN “10.0.0.0/24” “VLAN 5” Subnet- VLAN “10.0.0.0/24” “VLAN 5” Logical network definition “ Building 42” 1 - M

14 Steps to a successful deployment

19 DEMO Cisco Nexus 1000V

20 Why network virtualization?

21 Network Virtualization using Generic Routing Encapsulation (NVGRE)

22 DEMO Network Virtualization

23 Where to get more info – Channel 9 @ Microsoft  VIR303 An Overview of Hyper-V Networking in Windows Server 2012  B291 Cisco Networking Solution In Hyper-V  B312 Network Management in VMM (Part 1)  B313 Network Management in VMM (Part 2)  MGT315Networking in VMM SP1  HTTPwww.addlevel.se/blogg (this presentation)

24 UTVÄRDERING  Fyll i utvärderingen så att vi kan bli ännu bättre till nästa gång!  Antigen via länken du fick med din biljett eller vid någon av datorerna i TrueSec:s monter  Tävla samtidigt om en HP Elitepad 900 (Vinnaren presenteras i Utställarfoajén direkt efter sista sessionen). KVÄLLSMINGEL  Best of MMS avslutas med ett gigantiskt mingel på närliggande Dubliner direkt efter dagens sista session!  Microsoft och LabCenter bjuder på god öl och ett unikt tillfälle för experter, branschkollegor och eventdeltagare att mingla tillsammans.  Vi ses väl där?
