Customer problems with networking

BACKGROUND• Network virtualization lags behind compute and

storage• Administration within the data center may be

soiled

THE CHALLENGES• Physical network configuration is not flexible• Workloads tied to underlying hardware

configurations• Configuration changes are manual and

cumbersome• Diverse network infrastructure requires vendor-

specific management and control• Greater VM mobility and density difficult to

achieve

What is Software Defined Networking?

8

Enables software to dynamically manage the network by:

Enabling integrated policies that span physical and virtual networks

Abstracting workloads from the physical network

Controlling datacenter traffic flow

Problems solved• Creates VM mobility across

datacenter, hoster cloud or Azure without network constraints

• Provides ability to import customer IP addresses and network topology

• Helps remove VLAN constraints

• Helps eliminate hierarchical IP address assignment for virtual machines

tenant VMs with integral S2S VPN and NAT• Enterprises have virtualized networks split

across different datacenters or virtualized networks (NVGRE aware) communicating to physical networks (NVGRE unaware)

Solution• Multi-tenant VPN gateway in Windows Server

2012 R2 Preview• Integral multitenant edge gateway for

seamless connectivity • Guest clustering for high availability• BGP for dynamic routes update• Encaps/Decaps NVGRE packets• Multitenant aware NAT for Internet access

Controlling Datacenter traffic flow

16

What it means:• Provides ability to control physical network

hardware directly from applications

• Enforces routing policies on the fly

• Requires programmable hardware that uses a standard protocol like OpenFlow, Cisco OnePK and so on.

Challenges:• Adds complexity to the application

• Creates challenges in heterogeneous environment

Is it production ready?• Applicable to certain classes of applications like

Microsoft Lync, Network diagnostic tools, high fidelity video games

• Most Line of Business applications and workloads may not need this level of control

NIC Teaming

Virtual adaptersVirtual adapters

NIC Teaming

Team network adapter


Operating system• Provides network fault tolerance and continuous availability when network adapters fail by teaming multiple network interfaces

• Supports all vendors in-box

• Facilitates local or remote management through Windows PowerShell or UI

• Enables teams of up to 32 network adapters

• Aggregates bandwidth from multiple network adapters

• Includes multiple nodes: switch dependent and independent

8 x 1Gb NICs – 8Gb throughput



NIC Teaming

Virtual adaptersVirtual adapters

Dynamic NIC Teaming



TCP streams or "flows” are generally not continuous

Groups of packets sent between flows are called “flowlets”

Dynamic load balancing detects breaks in a flow of sufficient length to minimize possibility of packet reordering

Flows can be moved to other team members on flowlet boundaries to rebalance traffic

Dynamic LBFO maximizes resource utilization in teamed NICs by balancing loads across all NIC team members

Ideal when there are fewer VMs per team

• Compatible with SMB Multichannel for load balancing and failover



Dynamic Virtual Machine Queue

Without VMQ

• Hyper-V Virtual Switch is responsible for routing & sorting packets for VMs

• This leads to increased CPU processing, all focused on CPU0

With VMQ

• Physical NIC creates virtual network queues for each VM to reduce host CPU

With Dynamic VMQ

• Processor cores dynamically allocated for a better spread of network traffic processing

• Most 10Gbps and in-box NICs SR-IOV capable

Benefits

• Maximizes use of host system processors and memory

• Reduces host CPU overhead for processing network traffic (by up to 50%)

• Reduces network latency (by up to 50%)
