Networking Fabric in
Hyper-V and VMM

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

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

UTVÄRDERING
KVÄLLSMINGEL
 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
 Best of MMS avslutas med ett gigantiskt
mingel på närliggande Dubliner direkt
efter dagens sista session!
 Tävla samtidigt om en HP Elitepad 900
(Vinnaren presenteras i Utställarfoajén
direkt efter sista sessionen).
 Microsoft och LabCenter bjuder på god öl
och ett unikt tillfälle för experter,
branschkollegor och eventdeltagare att
mingla tillsammans.
 Vi ses väl där?
