Network Controller
  • Requires Server 2016 Datacenter Edition
  • What is it?
  • A Centralized point to configure, manage and
    troubleshoot your physical and virtual network
    infrastructure in your Datacenter
  • Automate network infrastructure instead of manual
    configuration
  • A highly available and scalable server Role
  • Network Controller supports both domain and
    non-domain environments
  • Network Controller authenticates users and
    network devices by using Kerberos

  • Non-domain environments, require certificates for
    authentication
  • Network Controller provides two application
    programming interfaces (API)
  • Southbound API allows Network Controller to
    communicate with the network
  • Northbound API allows you to communicate with
    Network Controller

Network Controller Northbound API allows you to
configure, monitor, troubleshoot, and deploy new
devices on the network by using
Network Controller Northbound API
  • PowerShell
  • Management Applications, such as
  • System Center Virtual Machine Manager (SCVMM)
  • System Center Operations Manager (SCOM)

Test Lab
  • Network Controller in a test lab environment, run
    the Network Controller server role on a single
    physical server (without using Hyper-V) or on a
    Hyper-V virtual machine (VM) that is installed on
    a Hyper-V host

11
Production
  • Deploy a cluster by using either three physical
    servers (without Hyper-V) or by using three VMs
    that are installed on three Hyper-V hosts

Firewall Management
  • Configure and manage
  • Allow/deny firewall Access Control rules for your
    VMs for both East/West and North/South network
    traffic in your datacenter

www.netcomlearning.com info_at_netcomlearning.com

14
Software Load Balance Management
  • Multiple servers can host the same workload,
    providing high availability and scalability

www.netcomlearning.com info_at_netcomlearning.com
(888) 563 8266
15
Virtual Network Management
  • Deploy and configure Hyper-V Network
    Virtualization
  • Hyper-V Virtual Switch and virtual network
    adapters on individual VMs
  • Store and distribute virtual network policies

www.netcomlearning.com info_at_netcomlearning.com
(888) 563 8266
16
RAS Gateway Management
  • Deploy, configure, and manage Hyper-V hosts and
    virtual machines (VMs) that are members of a RAS
    Gateway pool
  • Provides gateway services to your tenants
  • Note
  • In System Center Virtual Machine Manager, RAS
    Gateway is named Windows Server Gateway

Server 2016 NIC Teaming
  • Server 2016 NIC teaming provides
    hardware-independent bandwidth aggregation and
    transparent failover for both physical and
    virtualized servers

Reliable and Easy to Configure
  • In Server Manager, click Local Server.
  • In the Properties pane locate NIC Teaming, and
    then click the link
  • Disabled to the right. The NIC Teaming dialog box
    opens.
  • In Adapters and Interfaces, select the network
    adapters that you want to add to a NIC Team.
  • Click TASKS, and then click Add to New Team.

Virtual Machine Queue (VMQ)
  • The Virtual Machine Queue (VMQ) is a hardware
    virtualization technology for the efficient
    transfer of network traffic (such as TCP/IP,
    iSCSI or FCoE) to a virtualized OS (Virtual
    Machine).
  • VMQ technology was patented in 2010 by Daniel
    Baumberger of Intel Corp
  • A VMQ capable NIC can use Direct Memory Access to
    transfer all incoming frames routed directly to
    a receive queue of a Virtual Machine via its MAC
    Address.
  • In VMQ different processors can process packets
    for different virtual machines. This eliminates
    the dependence on driver-based traffic exchanges
    and improves the transfer of network traffic.
  • VMQ can be enabled on Windows Server 2008 R2 or
    lster as long as the Hyper-V server role is
    installed.

www.netcomlearning.com info_at_netcomlearning.com
(888) 563 8266
28
  • The major benefit of VMQ is when it comes time
    for the vSwitch to do the routing of the
    packets. When incoming packets are indicated from
    a queue on the NIC that has a VMQ enabled, the
    vSwitch is able to direct the hardware link to
    forward the packet to the right VM extremely
    fast. This reduces the CPU cost of the routing
    functionality and causes a measurable decrease in
    latency.
  • VMQ is the mechanism used to spread networking
    traffic to multiple cores. Without VMQ, all of
    the networking traffic is done on a single core
    so the overall throughput is capped at 3.5Gbps
    on a 10Gbps network.
  • Two key PowerShell cmdlets for VMQ configuration
    are Get-NetAdapterVMQ and
  • Set-NetAdapterVMQ.
  • To determine if your adapter is capable of
    performing VMQ, run Get- NetAdapterVMQ. This
    will list all the adapters on your system that
    are capable of doing VMQ

www.netcomlearning.com info_at_netcomlearning.com
(888) 563 8266
29
  • If your adapter has VMQ enabled, to find out what
    queues are assigned on the NIC, use the
    PowerShell cmdlet, Get-NetAdapterVmqQueue

VMQ Summary
  • VMQs purpose is to load-balance network resources
    across VMs and NICs
  • To increase the effective capability of a
    servers physical hardware,
  • specifically the NIC and Processor
