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 •

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


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

R2






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

Windows Server 2016

Windows Server 2016

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


Windows Server 2016

Windows Server 2016

Windows Server 2016

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

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

level

–VXLAN and NVGRE support

–Virtual Firewall

–Software Load Balancer

– Improved Gateways

–RDMA using vNICs

–And much much more…


Production 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


#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:

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


Much more

• Compatible with Connected Standby

• Discrete device assignment

• Host resource protection


ONE MORE THING…


Core Based Licensing


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.

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.
