Tenant Deployment Multi-Tier LOB Application

Tenant Deployment Multi-Tier LOB Application

• Inbox feature for integrated management of IP addresses, domain names, and device identities

• Tightly integrates with Microsoft DNS and DHCP servers

• Provides custom IP address space display, reporting, and management

• Audits server configuration changes and tracks IP address use

• Migrates IP address data from spreadsheets or other tools

• Monitors and manages specific scenario-based DHCP and DNS services

• IP utilization &

trend

• Audit config

• Disaster Recovery

• Multiple instance

deployment

• SQL Server

database

• Extensive PS

support

• Cross AD Support

• IP addressing management of

physical and virtual networks (SCVMM

integration)

• Integrated IP addressing, DNS and

DHCP management

• Granular RBAC to manage IP

address space, DHCP & DNS

• Delegated administration

within and across datacenters

• Automatic server discovery

• Single console DHCP and DNS

management across datacenters

• Management of granular DNS

properties

• Network functions that are being performed by hardware appliances are increasingly being virtualized as virtual appliances

• Virtual appliances are quickly emerging and creating a brand new market

• Dynamic and easy to change because they are a pre-built, customized virtual machine.

• It can be one or more virtual machines packaged, updated, and maintained as a unit.

• Microsoft included a standalone gateway as a virtual appliance starting with Windows Server 2012 R2

Load Balancers

Microsoft provides key virtualized network functions with Windows Server

1

Deploy virtual appliances from vendors of your choice

2Deploy, configure & manage virtual appliances with the Network Controller

3

Hyper-V can host the top guest OS’s that you need

4

• Included within Windows Server

• It is a network layer, 5-tuple (protocol, source and destination port numbers, source and destination IP addresses), stateful, multitenant firewall

• Tenant administrators can install and configure firewall policies to help protect their virtual networks

• Managed via Network Controller and northbound APIs

• Highly scalable, manageable, and diagnosable software-based firewall

• Freedom to move tenant virtual machines to different compute hosts without breaking tenant firewall policies

DCB Bandwidth management by traffic class

Not compatible with vSwitch

RDMA SMB Direct – fast storage and live

migrations

Not compatible with vSwitch or LBFO

VMQ VM traffic acceleration

RSS Native traffic acceleration

Operates in VM with SR-IOV VF

Software vRSS Spreads loads across VM CPUs

Address checksum offloads

LSO – Offloads large sends

RSC Coalescing in native stack

TCP Chimney Offload

SR-IOV For high performance networking in VMs

NVGRE task offload

• Teaming integrated into the Hyper-V switch

• Targeted at supporting SDN-switch capabilities:• Packet Direct

• Converged vNIC

• SDN-QoS

• Supported only when using SDN-Extension

• Limitations in this release:• Switch-independent only

• Dynamic and Hyper-V port mode load distributions only

• Managed by VMM or PowerShell, not NIC Teaming GUI

• Only teams identical ports (same manufacturer, same driver, same capabilities) (e.g., dual port NIC)

• Switch must be created in SET-mode. (SET can’t be added to existing switch.)

• New-VMSwitch -name SETswitch -NetAdapterName“NIC1",“NIC2“ -EnableEmbeddedTeaming $true

• DCB policies• Can be set on per-NIC basis

• Can be set on NICs bound to Hyper-V switch

• PowerShell to enable on SET NICs

Management OS

DCB policies configured for Mgmt, Storage, Migration & Clustering traffic.

Utilizes SMB Multichannel & SMB Direct

Hyper-V vSwitch

VM(s) Management OS

Hyper-V vSwitch with SET

VM(s)

• Allows host vNICs to expose RDMA capabilities to kernel processes (e.g., SMB-Direct)

• With SET, allows multiple RDMA NICs to expose RDMA to multiple vNICs (SMB Multichannel over SMB-Direct)

• With SET, allows RDMA fail-over for SMB-Direct when two RDMA-capable vNICs are exposed

• Operates at full speed with same performance as native RDMA

• Today’s NDIS for Windows

• Is NDIS in its current form enough for 100G?

• What can we do better?

• Similar to DPDK Technology for Intel NICs

Internet

• Lightning fast lock-free IO model

• Coexists with traditional NDIS data path

• Gives apps direct access to CPU, memory, and NIC capabilities

• App now decides when it wants to send/receive using polling

• App owns buffer management

• App driven I/O for NFV

• Will work with most 10G NICs

Tenant Deployment Multi-Tier LOB Application

A centralized, programmable point of

automation to manage, configure, monitor,

and troubleshoot virtual and physical network

infrastructure in your datacenter

Can be deployed as single VM

(lab) or as a cluster of 3 physical

servers (no Hyper-V) or 3 VMs

on separate hosts.

• Highly available and scalable server role

• Southbound API

• Northbound API (Rest interface)

• Can manage:
