#1Nano Server

Nano Server installation optionJust enough OS

Containers and modern applications

Full GUI

Specialized workloads

Third-party applications

RDS experience

Server Core

Lower maintenance server environment

Existing VM workloads

Nano Server

Just Enough OS

Provides higher density, reduced attack surface and servicing requirements

Ideal for cloud inspired infrastructure

• Smaller image size, smaller attack surface, faster boot time

Ideal for next generation app development

• Built for containers and cloud-native apps

• Full developer experience with Windows SDK and Visual Studio

The next step in the journey…

Nano Server: A new headless, 64-bit only, deployment option for Windows Server

Deep refactoring with cloud emphasis• Cloud fabric & infrastructure (clustering, storage, networking)

• Born-in-the-cloud applications (PaaS v2, ASP.NET v5)

• VMs & Containers (Hyper-V & Docker)

Extend the Server Core pattern• Roles & features live outside of Nano Server

• No binaries or metadata in OS image

• Standalone packages install like apps

• Full driver support

• Antimalware

#2Shielded VMs & Security

Challenges in protecting high-value assets

Solution – Windows Server 2016 Hyper-V

Shielded Virtual Machines

Confidently protect sensitive customer data:

Designed for ‘zero-trust’ environments

Who is Shielded VMs for?

As a hoster,I can protect my tenants’ VMs and their data from datacenter admins

As a tenant,I can run my workloads in the cloud while meeting regulatory/compliance requirements

As an enterprise,I can enforce a strong separation between Hyper-V administrators and sensitive workloads

Linux Secure Boot

Providing kernel code integrity protections for

Linux guest operating systems

Works with:Ubuntu 14.04 and later

SUSE Linux Enterprise Server 12

PowerShell to enable:Set-VMFirmware “Ubuntu”-SecureBootTemplateMicrosoftUEFICertificateAuthority

Host Resource Protection

• Dynamically identify virtual machines that are not

“playing well” and reduce their resource allocation

• Pioneered in Azure and enabled by default

• Designed to help prevent a VM consuming excessive hardware resources

• Looks for patterns of activity that shouldn’t occur within a non-malicious VM

#3Networking & Storage Enhancements

Networking & Storage Enhancements

• Distributed Storage QoS (one or more virtual disks on

SOFS)

• Deduplication optimization for virtualized backup workloads

• VHDX improvements on ReFS

Storage Spaces Direct

Reliability, scalability, flexibility •

•

Storage Spaces Direct Scenarios

Hyper-converged Converged (Disaggregated)

Storage Replica

• Volume based block-level storage replication

• synchronous or asynchronous

• HW agnostic (any type of source / destination volume)

• SMB3 as transport protocol

• Leverages RDMA / SMB3 Encryption Multichanneling

• I/Os pre-aggregated prior to transfer

• Managed via Powershell, cluadmin, ASR

Storage Replica at a glance

ReFS Accelerated VHDX Operations

Resilient File System

It maximizes data availability, despite errors that

would historically cause data loss or downtime.

Taking advantage of an intelligent file system for:Rapid fixed disk creation

Rapid disk merge operations

GM16Demo ReFS

www.thomasmaurer.ch

#4PowerShell

PowerShell direct

• No network, no firewall requirements no nothing…

• Enter-PSSession –VMName VMName

• Invoke-Command –VMName VMName –ScriptBlock { Commands }

• connected to a W10 or WS 2016 TP host with VM that run W10 or WS 2016 TP

as the guest OS

• You need to be logged in with Hyper-V administrator credentials on the host.

• You need user credentials for the virtual machine.

• The virtual machine that you want to connect to must run locally on the host

and be booted.

#5Virtual Machines

VM Configuration & format

• Current at 8.0

• Might need to get manually updated

Update-VmVersion vmname (or vmobject)

• VM needs to be off

• Format is now binary

• .VMCX

Hot Add/Remove

• Add vNICs to a running VM

• Change memory of a running VM (add only if memory is available)

#6Clustering

Rolling Cluster upgrade

• Stay in mixed mode during an upgrade of your cluster

• No more downtime

• Stays at 2012 R2 functional level until: Update-ClusterFunctionalLevel

• Works for Scale-Out File server failover cluster also

Cluster OS Rolling Upgrade Mixed OS mode is a new transition state for Failover

Clusters Optimizations don’t run

New features are not available

Do not plan on running your cluster in Mixed OS Mode for longer than one month

Cluster OS Rolling Upgrade Process

Start with a Windows Server 2012 R2 cluster

All nodes running Windows Server 2012 R2

The workload supports Cluster OS Rolling Upgrade process

Windows Server 2012 R2

Cluster Functional Level = Windows Server 2012 R2






Migrate Workloads Off Cluster Node

Pause | Drain the node







Failover Cluster


Evict Idle Cluster Node







Failover Cluster


Re-Provision Node

Install New OS

Install and Configure any Workload Requirements






Windows Server 2016

Failover Cluster


Re-Add Node To Cluster

Using Cluster UI or PowerShell

Cluster Functional Level Remains Windows Server 2012 R2

Virtual machine upgradesNew virtual machine upgrade and servicing processes

Compatibility mode: When a VM is migrated to a Windows Server 2016 host, it will remain in Windows Server 2012 R2 compatibility mode.

Upgrading a VM is separate from upgrading host.

VMs can be moved back to earlier versions until they have been manually upgraded.

Update-VMVersion vmname

Once upgraded, VMs can take advantage of new features of the underlying Hyper-V host.

Servicing model: VM drivers (integration services) updated as necessary.

Updated VM drivers will be pushed directly to guest operating system via Windows Update.

By running Update-VMVersion,VM will be upgraded to newest hardware version

and can use the new Hyper-V features

v8 v8 v8

VM Servicing

Windows 8.1 / Windows Server 2012 R2:VM drivers (integration services) updated with each new host release

Required that VM driver version matches the host

Drivers shipped with host operating system

Windows 10 / Windows Server 2016:VM drivers (integration services) updated when needed

Require latest available VM drivers for that guest operating system

Drivers delivered directly to the guest operating system via Windows Update

Clustering

• Storage Replica

• Cloud Witness

• Virtual Machine Resiliency

• Site-aware Failover Clusters

• Workgroup & Multi-domain clusters

#7Hyper-V Manager

Hyper-V manager

• Updated Icons

• Alternate Credentials Support

• Managing earlier versions

• Updated Management Protocol

#8Production Checkpoints

Production Checkpoints

• Allows you to create “point-in-time” images of a VM

• Full support for application workloads

• VSS on windows (application-consistent)

• File system buffer flush on Linux (file-consistent)

• Still can switch to the standard method

• New VMs use production checkpoints as default

• Fixes the “wrong usage of checkpoints”

• NOT a backup solution

• Native CBT will be implemented for backup vendors

#9Nested Virtualization

Nested Virtualization

• Possible in Windows 10 build 10565 (with restrictions)

• Possible in TP5

• Dynamic Memory needs to be off

GM16Servicing Model

LTSB servicing model

This is the traditional servicing model Windows Server has always used

5 + 5 years of servicing

Security and quality fixes only

No new features or functionality

Two Windows Server 2016 installation options use this model

Server with Desktop Experience

Server Core

Current Branch for Business (CBB)

Nano Server will be CBB only

What does this change?

Nano Server will not have an LTSB with Windows Server 2016 and therefore not have 5+5 years of servicing

Nano Server installations will have to move forward to future CBB releases of Nano Server to continue to be serviced

Licensing Nano Server will require Software Assurance (SA)

What doesn’t this change?

The quality, features, and functionality of Nano Server

Installation of new CBBs are always controlled by administrators, no forced upgrades

GM16Licensing

Core Based Licensing

Windows Server 2016 Licensing

• License all the physical cores in the server

• Minimum of 8 core licenses required for each proc

• Minimum of 16 core licenses required for each server

• Core licenses will be sold in packs of two.

• 8 two-core packs will be the minimum required to license each physical server.

• The two-core pack for each edition is 1/8th the price of a two proc license for

corresponding 2012 R2 editions.
