Module 2Storage, Networking
and Availability in Windows Server 2012
Module Overview
Storage EnhancementsWhat's New in Remote AccessNew and Improved Networking Technologies• Availability Enhancements
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
