Workloads

Online VHDX Resize

Expand Virtual SCSI Disks

1. Grow VHD & VHDX files whilst attachedto a running virtual machine

2. Then expand volume within the guest

Shrink Virtual SCSI Disks

3. Reduce volume size inside the guest

4. Shrink the size of the VHDor VHDX file whilst the VM is running

Online VHDX Resize provides VM storage flexibility

Virtual Receive Side Scaling

• vRSS makes it possible to virtualize traditionally network intensive physical workloads

• Extends the RSS functionality built into Windows Server 2012

• Maximizes resource utilization by spreading VM traffic across multiple virtual processors

• Helps virtualized systems reach higher speeds with 40 Gbps and 100 Gbps NICs

• Requires no hardware upgrade and works with any NICs that support RSS

Provides Near-Line Rate to a VM on Existing Hardware

Storage Quality of Service

• Allows an administrator to specify a maximum IOPS cap

• Takes into account incoming & outgoing IOPS

• Configurable on a VHDX by VHDXbasis for granular control whilst VM is running

• Prevents VMs from consuming allof the available I/O bandwidth tothe underlying physical resource

• Supports Dynamic, Fixed& Differencing

Virtual Machine Live Cloning

Export a clone of a running VM

• Point-time image of running VMexported to an alternate location

• Useful for troubleshooting VMwithout downtime for primary VM

Export from an existing checkpoint

• Export a full cloned virtual machinefrom a point-in-time, existing checkpoint of a virtual machine

• Checkpoints automatically merged into single virtual disk

Duplication of a Virtual Machine whilst Running

VM1 VM2

1 User Initiates an export of a running VM

2Hyper-V performs a live, point-in-time export of the VM, which remains running, creating the new files in the target location

3 Admin imports new, powered-off VM on the target host, finalizes configuration and starts VM

4 With Virtual Machine Manager, Admin can select host as part of the clone wizard

Live Migration Compression

• Utilizes available CPU resources on the host to perform compression

• Compressed memory sent across the network faster

• Operates on networks with less than 10 gigabit bandwidth available

• Enables a 2X improvement in Live Migration performance

Live Migration over RDMA

• Remote Direct Memory Access delivers low latency network, CPU utilization & higher bandwidth

• Supports speeds up to 56Gb/s

• Windows Server 2012 R2 supports RoCE, iWARP & Infiniband RDMA solutions

• Delivers the highest performance forLive Migrations

• Cannot be used with Compression

Guest Clustering with Shared VHDX

• VHDX files can be presented to multiple VMs simultaneously, as shared storage

• VM sees shared virtual SAS disk

• Unrestricted number of VMs canconnect to a shared VHDX file

• Utilizes SCSI-persistent reservations

• VHDX can reside on a Cluster Shared Volume on block storage, or onFile-based storage

• Supports both Dynamic and Fixed VHDX

Once Hyper-V Replica is enabled, VMs begin replication

• 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

Hyper-V Replica | Extended Replication

• Once a VM has been successfully replicated to the replica site, replicacan 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 Site
