Lesson 1: Storage Enhancements

New Storage Features in Windows Server 2012Storage Spaces and Storage PoolsSMB 3.0iSCSI Target Server• Microsoft Online Backup

New Storage Features in Windows Server 2012

• Multi-terabyte volumes• Data Deduplication• Storage Spaces and Storage Pools• Unified remote management of File and Storage Services

in Server Manager.• Server Message Block (SMB) 3.0• iSCSI Target server• Resilient System(ReFS)• Scale-Out File Server• Windows® PowerShell® cmdlets for File and Storage

Services.

Storage Spaces and Storage Pools

• Provides RAID functionality without the need for RAID hardware or software

• Enables striping, mirroring, and parity• Can be configured from Server Manager, Control Panel, or

PowerShell• Provisioning Schemes

Thin Provisioning space Fixed provisioning space

To create a new storage pool, click Tasks in the Storage Pools tile and select New Storage Pool:

The new storage pool wizard starts:

On completing the wizard, you have the option of creating a new virtual disk when the wizard closes:

The New Virtual Disk Wizard lets you provision storage from your new pool to create virtual disks that span one or more physical disks within your pool:

After you have selected a pool and specified a name for your new virtual disk, you can choose whether to create a simple virtual disk or one with resiliency:

Next, you will select either fixed or thin as the provisioning type

Once you’ve finished creating your storage pools, virtual disks, and volumes, you can manage them using the Storage Pool page of Server Manager:

SMB 3.0

High Speed

SMB Multi-Channel

SMB Direct

SMB Encryption

iSCSI Target Server• iSCSI Target is included with Windows Server 2012 as a

role service• New Features include

Authentication Query initiator computer for ID.

• Provides iSCSI network storage to provide network storage to systems including: Application servers Hyper-V Clustering Diskless systems

Microsoft Online Backup• Back up to the cloud• Uses Windows Server Backup• Extensible to enable third-party providers

Lesson 2: What's New in Remote Access

DirectAccess and Unified Remote Access• BranchCache

DirectAccess and Unified Remote Access• DirectAccess

Improved Management Simplified Deployment Performance and Scalability New Deployment Scenarios

• Unified Remote Access One gateway can provide clients-to-site connectivity and site-

to-site connectivity Ideally suited to a hybrid cloud environment

BranchCache• BranchCache caches data from head office to branch

office to reduce network bandwidth and improve performance at the branch office

• In Windows Server 2012, there are a number of improvements: Performance

• Performance is improved through chunking improvements and caching starting sooner.

Manageability• Manageability is improved through more straightforward

deployment and PowerShell integration. Scalability

• Scalability is improved by supporting multi-terabyte caches

Lesson 3: New and Improved Networking Technologies

Networking ChangesDNSSECData Center TCPData Center BridgingNIC Improvements• High Performance Networking Offloads

Networking Changes• DNSSEC• Extensible Authentication Protocol (EAP) for Network Access

Landing Page• 802.1X Authenticated Wireless Access Overview• Data Center Bridging (DCB)• Data Center Transmission Control Protocol (DCTCP)• Network Direct• IPSecTOv2• SR-IOV• Receive Segment Coalescing (RSC)• Receive Side Scaling (RSS)• Quality of Service (QoS)• NIC Teaming (Load balancing and failover (LBFO))

Data Center TCP• TCP traffic flow is interrupted in the presence of network

congestion, so it is affected regardless of the degree of that congestion

• DCTCP reacts to the amount of congestion• Traffic is smoothed• Buffer memory is dramatically decreased

Congested traffic

Smoothed traffic

Data Center Bridging• Reserves bandwidth by the type of network traffic• Requires DCB-capable NICs

Bandwidth Reservation: Live Migration Media Streaming Video Conferencing

NIC Improvements

NIC Teaming

Consistent Device NamingNIC 1

Demonstration: Configure NIC Teaming• Server Manager to enable NIC teaming, you can begin by right-

clicking the server you want. To configure and selecting Configure NIC Teaming:

NIC Teaming• In the New Team dialog box, configure the teaming mode

and other settings as desired:

NIC Teaming• Clicking OK completes the process and, if successful, the new

team will be displayed in the Teams tile of the NIC Teaming dialog box:

High Performance Networking Offloads• Offloading data transfers with RDMA• Offloading security with IPSecTOv2• Offloading networking for virtual machines with SR-IOV• Coalescing received packets with RSC• Scaling out received network traffic with RSS

Lesson 4: Availability EnhancementsCluster ScalabilityFile Server High AvailabilityDHCP High AvailabilityCluster Aware Updating• Introducing Hyper-V Availability

Cluster Scalability• Clustering is now much

more scalable• Clustering is now

available in StandardEdition

File Server High Availability• Scale out to provide scalability• Automatic failover to provide availability with zero

downtime failovers

CSV

Scale-Out File Servers

DHCP High Availability• DHCP Failover is a new feature in Windows Server 2012• Lease information is replicated between the two DHCP

servers. • If one of the DHCP servers fails, then the other DHCP

server services the clients for the whole subnet. • Only IPv4 scopes and subnets are supported because

IPv6 uses a different IP address assignment scheme.

Cluster Aware Updating• One command performs an update on all nodes in turn:

1. Fails over the workload2. Applies updates3. Reboots if necessary4. Fails back the workload5. Continues to next node

• Cluster Updating Modes Remote-updating mode Self-updating mode.

Introducing Hyper-V Availability• Virtual machine monitoring• Live Migration
