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

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?
