4/33

Windows Hardware Error Architecture (W

Adds support for WHEA Detects errors in memory, and hand

them to ensure that applications co

running. Memory fault won't take down an e

server, just the one affected VM


5/33

How it works

When there is a memory problem suspend all the VMs

determine if the error can be isolated tosingle VM

terminate that VM, mark the memory pbad

restart the affected VM while resuming

paused VMs

Others Memory Enhancements

No longer need toshutdown the VirtualMachine when you wantto configure Min and

Max Memory (DynamicMemory)

Memory with DynamicMemory is 2TB

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

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

The Solution

Microsoft Bridging solution ARP proxying (for IPv4)

Neighbor Discovery proxying (for IPv6)

The bridge maintains an internal mappin

between the virtual NICs IP address andMAC address to ensure that the packets from the external world are sent to theappropriate virtual NIC.


17/33

The Solution cont.

Hyper-V integrates the bridge as part of crthe virtual switch such that when you createxternal virtual switch using a WiFi adapterV will:

Create a single adapter bridge connected to adapter

Create the external virtual switch

Bind the external virtual switch to use the brid

instead of the WiFi adapter directly

Q & A

Thank you!

25/33

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 ho

virtual HBAs per virtual machine- New Storage Live Migration feature: move virtual disks between diffestorage (NAS, DAS, and SAN) - No downtime

Networking:- Extensible Virtual Switch that allows third-party switches to work with

Server network


26/33

Hyper-V Manager Enhancement

Virtual migration:- Move a virtual machine from one server to another without using shared storage; use locasystem (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

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 alw

Virtual Machine Copy Recovery:- Hyper-V Replica feature allows replicate VMs to another Hyper-V host (good for DR site s


27/33

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 to file corruption.


28/33

Hyper-V Replica

Hyper-V Replica is asynchronous, application consistent, virtual macreplication built-in to Windows Server 8.

Unlimited VM replication in the box

With Hyper-V Replica, you canreplicate a virtual machine fromone location to another withHyper-V and a networkconnection.

NIC Teaming

For performance and redundancy, we install multiplenetwork card and configure with NIC Teaming utility.

Different brand and model of NIC often cannot bemixed.

Windows 8 Enhancement

Windows Server 8 NIC teaming provides reliabilityagainst hardware failures

Can mix different brand and model of network cards

No need for 3rd

utilities and drivthis.

NIC teaming works either in the root or the guest
