2. Enhancement in Hyper-V v3.0
• Memory
• Storage
• Network

3. Windows Server 8 Hyper-V (v3.0)
MEMORY

4. Windows Hardware Error Architecture (WHEA)
• Adds support for WHEA
• Detects errors in memory, and handles
them to ensure that applications continue
running.
• Memory fault won't take down an entire
server, just the one affected VM

5. How it works
• When there is a memory problem
– suspend all the VMs
– determine if the error can be isolated to a
single VM
– terminate that VM, mark the memory page as
bad
– restart the affected VM while resuming the
paused VMs

6. Others Memory Enhancements
• No longer need to
shutdown the Virtual
Machine when you want
to configure Min and
Max Memory (Dynamic
Memory)
• Memory with Dynamic
Memory is 2TB

7. Windows Server 8 Hyper-V (v3.0)
STORAGE

8. Welcome VHDX !
• Beyond 2TB limit in VHD
• New limit at 16TB
• Only usable in Windows Server 8
• Improvement in term of:
– performance
– larger block size
– more resilient to corruption

9. Playing Around with VHD(X)
Mounting a VHD(X)
- Access your VM data easily
Ejecting a VHD(X)
- Eject VHD(X) just like DVD
Boot from a VHD(X)
- Boot from anywhere

10. Live Storage Migration
• Eliminate “Quick Storage Migration” in
SCVMM 2008 R2 downtime requirement.
• Moving VHD(X) while your users still using
it.

12. Others Storage Enhancements
• Offloaded Data Transfer (ODX) – similar to VAAI
• Virtual Fibre Channel Support (4 vHBA, direct access to
SAN LUNs using MPIO)
• Data deduplication
• BitLocker volume encryption for clustered disks,
• Built-in replication
• Hardware snapshotting
• Remote Direct Memory Access (RDMA) networks for
SMB storage

13. Windows Server 8 Hyper-V (v3.0)
NETWORK

14. Wireless Network Support
• Creating an external network switch is
simple in current Hyper-V
• Same steps but different ways

15. Networking
between VM
and external
machine using
wired
connection

16. The Solution
• Microsoft Bridging solution
– ARP proxying (for IPv4)
– Neighbor Discovery proxying (for IPv6)
• The bridge maintains an internal mapping
between the virtual NIC’s IP address and its
MAC address to ensure that the packets coming
from the external world are sent to the
appropriate virtual NIC.

17. The Solution …cont.
• Hyper-V integrates the bridge as part of creating
the virtual switch such that when you create an
external virtual switch using a WiFi adapter, Hyper-
V will:
– Create a single adapter bridge connected to the WiFi
adapter
– Create the external virtual switch
– Bind the external virtual switch to use the bridge,
instead of the WiFi adapter directly

18. Networking
between
VM and
external
machine
using WiFi
connection

19. Bandwidth Network Management
• Manage the Network Bandwidth with a
Maximum and a Minimum value
• SLAs for hosted Virtual Machines
• Control per VMs and not per HOST

21. Others Network Enhancements
• SR-IOV
• Native NIC teaming
• Cisco VXLAN – Nexus

22. HYPER-V enhancement with CISCO

23. Q&A
Thank you!

25. Hyper-V Manager Enhancement
Scalability:
- Support 160 logical processors per host
- 512GB of memory per virtual machine
- New virtual disk format (VHDX)
Storage:
- Virtual Fibre Channel for virtual guests
- Clusters can connect to SAN fabrics through HBAs on the physical host, support 4
virtual HBAs per virtual machine
- New Storage Live Migration feature: move virtual disks between different types of
storage (NAS, DAS, and SAN) - No downtime
Networking:
- Extensible Virtual Switch that allows third-party switches to work with the Windows 8
Server network

26. Hyper-V Manager Enhancement
Virtual migration:
- Move a virtual machine from one server to another without using shared storage; use local storage of each
system (design for planned migration, not a replacement for HA)
- Known as Share-Nothing Live Migration
Multiple Concurrent Live Migration:
- No limit to the number of concurrent migrations
Performance Improvements:
- Hyper-V ODX (offload data transfer) engine can utilize back-end shared storage subsystem that supports
ODX
- Reduce the CPU usage during data transfers (processing power handle by the storage)
- Allow mapping of a virtual machine to specific CPU cores (ensure dedicated resources always available)
Virtual Machine Copy Recovery:
- Hyper-V Replica feature allows replicate VMs to another Hyper-V host (good for DR site setup)

27. Virtual Hard Disk Enhancement (VHDX)
• VHD = max 2TB (for > 2TB, need to use pass-through disk)
• VHDX = max 16TB (may increase the limit at later time)
• Conversion between
• VDH to VHDX format
• VHDX to VHD format
• VHDX have great improvement in term of performance, larger block size and is more resilient
to file corruption.

28. Hyper-V Replica
• Hyper-V Replica is asynchronous, application consistent, virtual machine
replication built-in to Windows Server 8.
• With Hyper-V Replica, you can
replicate a virtual machine from
one location to another with
Hyper-V and a network
connection.
• Unlimited VM replication in the box
