Storage, Networking and
Availability in Windows
Server 2012
Module Overview
• Storage Enhancements
• What's New in Remote Access
• New and Improved Networking Technologies
• Availability Enhancements
Lesson 1: Storage Enhancements
• New Storage Features in Windows Server 2012
• Storage Spaces and Storage Pools
• SMB 3.0
• iSCSI 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
•

Manageability
•

Performance is improved through chunking improvements
and caching starting sooner.
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 Changes
• DNSSEC
• Data Center TCP
• Data Center Bridging
• NIC 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 Naming
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 Enhancements
• Cluster Scalability
• File Server High Availability
• DHCP High Availability
• Cluster Aware Updating
• Introducing Hyper-V Availability
Cluster Scalability
• Clustering is now much
more scalable
• Clustering is now
available in Standard
Edition
File Server High Availability
• Scale out to provide scalability
• Automatic failover to provide availability with zero
downtime failovers
Scale-Out File Servers
CSV
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 workload
2.
Applies updates
3.
Reboots if necessary
4.
Fails back the workload
5.
Continues to next node
• Cluster Updating Modes

Remote-updating mode

Self-updating mode.
Introducing Hyper-V Availability
• Virtual machine monitoring
• Live Migration
