This document summarizes key features coming in the next version of Hyper-V, codenamed "VNext" or V3, which will be included in Windows 8. Some of the major new capabilities highlighted include increased scalability up to 160 processors and 2TB of RAM per host, and 512GB of RAM per virtual machine. Other improvements include enhanced data mobility options using new replication features, support for larger virtual hard disks up to 16TB with more robust formats, support for shared storage over SMB file servers, and quality of service features for managing network bandwidth.

Pre-configuration for IP settings for primary/remote location
Key Features:
Seamless integration with Hyper-V and Clustering
Automatically handles all VM mobility scenarios (e.g. Live
migration)
Supports heterogonous storage between primary and recovery

17. Virtual Machine Fibre Channel
Hyper-V Hyper-V  New in Windows 8:
Host Host FibreChannel into the
guest. This gives
customers another option
for guest clustering.
CSV  Hyper-V will use hardware
offloads:
 ODX
External Storage Array  Trim

18. Remote File Server
Hyper-V supports file storage
Hyper-V Hyper-V
through the SMB protocol. This
Host Host
works in all scenarios, including
planned/unplanned failover and live
migration. You can cluster the file
server for availability and scalability.
Cross-cluster live migration requires
remote file servers.
File Server
Requirements:
 Requires updated protocol, SMB
2.2
 Requires remote VSS for host
based backup

19. Virtual Machine Snapshots
Great for capturing a
point in time
Testers can record exact
situation for bug repro
and continue
Testers can replay a
scenario over and over
Waiting for snapshot
merge is a thing of the
past
