#2Shielded VMs

Challenges in protecting high-value assets

Confidently protect sensitive customer data:
Designed for ‘zero-trust’ environments

#3
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

DEMO: REFS

#4
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.

#5
Virtual Machines

VM Configuration & Format
• Current at 7.1
• 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

#6
Clustering

Clustering
• Storage Replica
• Cloud Witness
• Virtual Machine Resiliency
• Site-aware Failover Clusters
• Workgroup & Multi-domain 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

Hyper-V Manager

Hyper-V manager
• Alternate Credentials Support
• Managing earlier versions
• Updated Management Protocol

#8
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…

#9
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:

#11
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.

#12
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.
