Replicate Hyper-V VMs from a
Primary to a Replica site
• Affordable in-box business continuity and
disaster recovery
• Configurable replication frequencies of 30
seconds, 5 minutes and 15 minutes
• Secure replication across network
• Agnostic of hardware on either site
• No need for other virtual machine
replication technologies
• Automatic handling of live migration
• Simple configuration and management

Extra Level of Resiliency
•
Once a VM has been successfully
replicated to the replica site, replica
can be replicated to a 3rd location
•
Chained Replication
•
Extended Replica contents match the
original replication contents
•
Extended Replica replication frequencies
can differ from original replica
•
Useful for scenarios such as SMB ->
Service Provider -> Service Provider DR

Windows Server 2008 R2 SP1
•
Introduced Dynamic Memory to enable
reallocation of memory automatically
between running virtual machines

Hyper-V Smart Paging
•
Reliable way to keep a VM running when
no physical memory is available
•
Performance will be degraded as disk is
much slower than memory
Used in the following situations:
•
VM restart
•
No physical memory is available
•
No memory can be reclaimed from other
virtual machines on that host

VHDX
Features
• Storage capacity up to 64 TBs
• Corruption protection during power failures
• Optimal structure alignment for large-sector
disks
Benefits
• Increases storage capacity
• Protects data
• Helps to ensure quality performance on
large-sector disks

Online VHDX Resize provides
VM storage flexibility
Expand Virtual SCSI Disks
1. Grow VHD & VHDX files whilst attached
to a running virtual machine
2. Then expand volume within the guest
Shrink Virtual SCSI Disks
1. Reduce volume size inside the guest
2. Shrink the size of the VHD
or VHDX file whilst the VM is running
Control allocation of Storage
IOPS between VM Disks
•
Allows an administrator to specify a
maximum IOPS cap
•
Takes into account incoming &
outgoing IOPS
•
Configurable on a VHDX by VHDX
basis for granular control whilst VM is
running
•
Prevents VMs from consuming all
of the available I/O bandwidth to
the underlying physical resource
•
Supports Dynamic, Fixed
& Differencing
Guest Clustering No Longer
Bound to Storage Topology
•
VHDX files can be presented to multiple
VMs simultaneously, as shared storage
•
VM sees shared virtual SAS disk
•
Unrestricted number of VMs can
connect to a shared VHDX file
•
Utilizes SCSI-persistent reservations
•
VHDX can reside on a Cluster Shared
Volume on block storage, or on
File-based storage
•
Supports both Dynamic and Fixed VHDX
Flexible choices for placement of Shared VHDX
VMs built on Optimized,
Software-Based Devices
Ease of Management & Operations
•
PXE boot from Optimized vNIC
•
Hot-Add CD/DVD Drive
Dynamic Storage
•
VMs have UEFI firmware with support
for GPT partitioned OS boot disks >2TB
•
Faster Boot from Virtual SCSI with Online
Resize & increased performance
Security
•
Removal of emulated devices reduces
attack surface
•
VM UEFI firmware supports Secure Boot
Enhancing VMConnect for
the Richest Experience
Improved VMBus Capabilities enable:
•
Audio over VMConnect
•
Copy & Paste between Host & Guest
•
Smart Card Redirection
•
Remote Desktop Over VMBus
Enabled for Hyper-V on both Server
& Client
Fully supports Live Migration of VMs
Simplifying Activation of
Windows Server 2012 R2 VMs
•
Activate VMs without managing
product keys on a VM by VM basis
•
VMs activated on start-up
•
Reporting & Tracking built-in
•
Activate VMs in remote locations, with
or without internet connectivity
•
Works with VM Migration
•
Generic AVMA key for VMs activates
against a valid, activated Windows
Server 2012 R2 Hyper-V host

What is Deduplication?
The act of finding and removing
duplication within data without
compromising its fidelity or integrity
Purpose: Store/Transfer less data
How it works:
Segment data into small variable sized
chunks
Identify and remove duplicate chunks
Replace duplicate copies of each chunk
with a reference to a single copy
Compress chunks
