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 

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
slide-6
SLIDE 6

Network bottlenecks…

  • In the host networking stack
  • In the NICs
  • In the switches
slide-7
SLIDE 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

…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

Hyper-V Host 1 Virtual Switch Extension Extension Extension Hyper-V Host 2 Virtual Switch Extension Extension Extension Hyper-V Host 1 Hyper-V Host 2 Logical Switch (VMM) Virtual Switch Extension Manager (VSEM) Extension (Capture) Extension (Filtering) Extension (Forwarding)

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
  • ch ett unikt tillfälle för experter,

branschkollegor och eventdeltagare att mingla tillsammans.

  • Vi ses väl där?
