Nano Server

• Headless server

• No UI

• Everything remotely managed

• Extremely low footprint

• Works with packages:

–Hyper-V

–SOFS

–DNS

–…

Challenges in protecting high-value assets

Confidently protect sensitive customer data:

Designed for ‘zero-trust’ environments

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 •

Use cases•

Cloud design points and management•

Storage Spaces Direct Scenarios

Hyper-converged Converged (Disaggregated)

DEMO: STORAGE SPACES DIRECT

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

DEMO: REFS

PowerShell

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.

DEMO: NANO SERVER & POWERSHELL DIRECT

Virtual 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

Integration Services

• No more ISO

• Delivered through Windows Update

• In the hands of the tenants now

• Linux Integration Services (LIS) or FreeBSD

Integration Services (BIS) can be built-in or require

download

Linux Secure Boot

• Booting with the Secure Boot option enabled

• Generation 2 required

• Ubuntu 14.04 (or later), SUSE Linux Enterprise Server

12 (or later), Red Hat Enterprise Linux 7.0 (or later)

and CentOS 7.0 (or later)

• Before booting first time:

– Set-VMFirmware vmname –SecureBootTemplate MicrosoftUEFICertificateAuthority

Hot Add/Remove

• Add vNICs to a running VM

• Change memory of a running VM (add only if

memory is available)

DEMO: HOT ADD AND REMOVE

SHIELDED VMS

Clustering

• Storage Replica

• Cloud Witness

• Virtual Machine Resiliency

• Site-aware Failover Clusters

• You can now upgrade a 2012 R2 Hyper-V cluster to

Windows Server 2016 with:

– No new hardware

– No downtime

– The ability to roll-back safely if needed

Rolling Cluster Upgrade

Cluster OS Rolling Upgrade

• Mixed OS mode is a new transition state for Failover

Clusters

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

Windows Server 2016

• Ready To Migrate Workloads Back

–Migrate workloads to Windows Server 2016 Node

–Validate functionality

Windows Server 2016

• Repeat For Remaining Nodes

Windows Server 2016

• All Nodes Are Upgraded

–Cluster Functional Level remains Windows Server 2012 R2

–Functionality is limited to Windows Server 2012 R2 levels

Windows Server 2016

• Upgrade Functional Level– Cluster Functional Level upgraded To Windows Server 2016:

Update-ClusterFunctionalLevel cmdlet

– New functionality added in Windows Server 2016 enabled

Windows Server 2016

Cluster Functional Level = Windows Server 2016

Windows Server 2016

• Upgrade is completed

Windows Server 2016

Cluster Functional Level = Windows Server 2016

Windows Server 2016

Failover Cluster

Hyper-V Manager

Hyper-V manager

• Alternate Credentials Support

• Managing earlier versions

• Updated Management Protocol

Networking Enhancements

Software Defined Networking

• Bringing Software Defined Networking to the next

–VXLAN and NVGRE support

–Virtual Firewall

–Software Load Balancer

– Improved Gateways

–RDMA using vNICs

–And much much more…

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

#10Nested Virtualization

Nested Virtualization

• Possible in Windows 10 build 10565 (with restrictions)

• Possible in TP5

• Only Intel at this point in time

• Dynamic Memory needs to be off

• Enabling requires specific scripts:

https://msdn.microsoft.com/virtualization/hyperv_on

_windows/user_guide/nesting

Container

What are Containers

LXC (Linux Containers) is an operating-system-level

virtualization environment for running multiple

isolated Linux systems (containers) on a single Linux

control host. Containers provide operating system-

level virtualization through a virtual environment that

has its own process and network space, instead of

creating a full-fledged virtual machine.

Bare-Metal

Virtual Machines

Container Run-time

Much more

• Compatible with Connected Standby

• Discrete device assignment

• Host resource protection

ONE MORE THING…

Core Based 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.

licensing-and-pricing/

Switch now!

• From September 1, 2016, through June 30, 2017, customers who switch workloads from VMware to Hyper-V can get free Windows Server Datacenter licenses when buying Windows Server Datacenter + Software Assurance.
