ความสามารถ Windows Server 2012 R2 ใหม่ TechEd: Windows Server 2012 R2 Features (MDC-B205)

1. TechEd: Windows Server 2012 R2 Features (MDC-B205)
This session was presented by Jef f Woosley, and covered the new f eatures coming up in Windows Server
2012 R2. Windows Server 2012 was the biggest OS release since Windows 2000, and R2 promises a
boatload of new f eatures.
Intro
Microsof t Cloud OS Vision
Private Cloud – Windows Server + System Center
Virtualization f or consolidation is NOT a cloud. Are you just virtualizing, then you are NOT doing
cloud computing.
Clould is reqestable, cloud is usage based, cloud is chargeable
People are highly f ocused on the hypervisor but completely overlook management
One Cloud OS Vision has three pillars and one consistent platf orm:
1. Private cloud is about control and security
2. Public cloud is about scale: Of f ice 365, Windows Azure, Azure Virtual machines
3. Service Provider is about customization
Windows Server 2012 powers the entire Azure inf rastructure
MS provisions 25K VMs a day f or test/dev
Windows Server 2012 R2 Enhancements
Focus: Datacenter without boundaries, cloud innovation everywhere, dynamic application delivery,
f lexible and consistent application platf orm, enable people-centric IT
Virtualization – Hyper-V 2012 R2
Cross-version live migration
Online VHDX resize
Automatic VM activation
Live VM export/cloning
Remote Access console via VMBus (does not rely on RDS or networking)
Live migration compression
Live migration with RDMA
More robust Linux support
Hyper-V 2012 R2 Demo
Teaser demo f rom the Hyper-V session later today. Showed a VM that was hammering storage and slowing
down all other VMs on the same host or SAN. With 2012R2 and enable minimum or maximum IOPS on a per-
VM database. IOMeter showed a drop f rom 20K IOPS to 100 IOPS, with a setting on the VM.

2. 2012R2 has enhanced Linux support. Full hot-add and remove of dynamic memory with Linux guests. Full on
dynamic memory, complete f eature parity with Windows implementation. Support f or f ull Linux backups in a
consistent state. File consistent backups with zero downtime. Similar to VSS f unctionality in Windows, but
f or Linux f ilesystems.
Clustering VMs without iSCSI or Fibre Channel shared storage. Can now share VHDX f iles between VMs f or
clustering. Fully supported in production environments. Cloud service provider can now provide clustering
services without having to expose iSCSI or raw LUNs to VMs.
Windows Server 2012 R2 Storage Enhancement
Azure does NOT use SANs. It uses cheap direct attached storage. SANs do not scale and are very
expensive. Laser f ocused on driving down cost per IOPS. Storage is cheap, IOPS is not.
Windows Storage Spaces now f eatures block-level automated data tiering
Data deduplication enhanced in R2 (now with running VMs)
Flexible resiliency options (enhanced in R2) – Three way mirrors, write-back cache,
Pooling of disks
Demoed creating a physical clustered f ile server using VMM 2012 R2. VMM connects to the baseboard
management controller (e.g. ILO) of the server, boots the server into WinPE, and deploys a standard VHDX
and conf igures the Windows OS f or f ile services. With a f ew clicks a share was created, and provisioned to
Hyper-V VMs f or storage.
Challenges of Guest Clustering (MDC-B337)
Shared VDHX enables guest clustering within a tenant without accessing raw LUNs or iSCSI disks
Software Defined Networking
Allows you to move VMs and workloads f rom private cloud to public cloud to service providers
Provides seamless experience f or business agility and ease of management
Live migration across subnets
Breaks VLAN scalability limits
Merge networks on same f abric
2012 R2 provides in-box multi-tenant edge gateway f or seamless connectivity to Azure and service
providers or internal networks
2012 R2 Gateway enables direct routing or NAT
System Center is the control plane, Windows server is the data plane
F5, Iron Networks, Huawei and Arista are providing additional gateway options
Cisco, NEC, 5 Nine (security), InMon (packet capture) f or Hyper-V extensions
Hyper-V 2012 R2 Replica
Broaden your coverage of business continunity with hybrid cloud solutions spanning on-prem and
the cloud
Enhanced in R2 f or cloud providers
Tertiary replication in the box
Hyper-V Recovery Manager (new) - Conf igurable down to 30s window, recovery orchestration with
Azure Hyper-V

3. Replica f requency options are 30s (new), 5 minutes, 15 minutes
Replica now supports pre-staging the data via of f line methods, then online sync the deltas
Hyper-V Recovery Manager has “recovery plans” f or runbook automation
