plays a critical role in serious disaster recovery strategies. Windows Server 2008 R2 failover clustering support introduced enterprise-class fault tolerance and recoverability to Microsoft’s server platform. Windows Server 2012 builds on this technology and offers important new and enhanced features that offer more expandability, non-stop storage availability for server applications, easier management, quicker automatic failover, and more options for designing failover clusters.
In addition to offering comprehensive Windows Server 2012 consulting services, LG Networks’ Microsoft-certified failover clustering experts can help you evaluate the benefits of adopting Windows Server 2012 clustering technology to build an advanced high-availability/disaster recovery solution, assist you to design and deploy a failover cluster environment powered by Windows Server 2012, provide online or on-premise consulting services and technical support for clustered physical servers or virtual machines, and show you how to streamline the management of clustered servers.
New and Improved Features of Windows Server 2012 Failover Clustering
With failover clustering, if any clustered servers (called nodes) stop working properly, other servers automatically and transparently take up (or failover) their workloads such as Exchange Server or SQL Server. Cluster Shared Volume (CSV) is a refinement of failover clustering that provides a consistent, shared namespace that clustered services and applications (called roles) can use to utilize shared storage regardless of the node that is currently running them. This ability to replace IT resources on the fly can dramatically enhance network availability and facilitate rapid recovery in case of a localized catastrophic event.
Cluster Shared Volumes Allow Cluster Nodes to Access the Same NTFS File System Simultaneously
The failover clustering enhancements built into Microsoft Windows Server 2012 include:
Failover clusters in Windows Server 2012 can scale to a greater number of nodes and virtual machines than clusters in Windows Server 2008 R2. Windows Server 2012 scales to 64 nodes and 8,000 virtual machines per cluster. In contrast, Windows Server 2008 R2 supports 16 nodes and 1,000 virtual machines per cluster.
Server Manager and Failover Cluster Manager
Windows Server 2012’s new Server Manager makes it easy to manage cluster nodes by enabling remote multi-server management as well as the remote installation of roles and features. Server Manager can also start Failover Cluster Manager, which provides a wealth of new features including new search, filtering, and custom views; the ability to select a defined set of VMs for performing desired operations such as live migration; one-click configuration of Cluster Shared Volumes (CSVs); and support for Hyper-V Replica for point-in-time replication of VMs.
Virtual Machine Mobility
Multiple live migrations including VM storage can be initiated at the same time to nodes with adequate resources and failed migrations are automatically retried. In addition, you can add or a virtual machine to a failover cluster while the VM is running.
Cluster Shared Volumes
Improvements to Cluster Shared Volumes (CSVs), which provide clustered VMs with common storage, include storage capabilities for additional clustered roles, the CSV proxy file system (CSVFS), support for BitLocker encryption, Direct I/O for faster access to file data, elimination of external authentication dependencies, integration with SMB Multichannel and SMB Direct for better performance and with Storage Spaces for lower-cost storage, and the ability to scan and fix volumes without service disruption.
Support for Scale-Out File Servers
The new clustered file server makes it possible to store server application data like Hyper-V virtual machine files on scale-out (known as active-active) file shares, offering performance and manageability similar to storage area network (SAN) solutions.
Cluster-Aware Updating (CAU)
This new feature allows the automation of software updates to the host operating system or other system components on clustered servers without downtime.
Monitoring and Managing VM Applications
This new capability enables high-level monitoring of applications hosted on clustered VMs running Windows Server 2012.
Integration with Active Directory Domain Services
Enhanced integration with Active Directory Domain Services (AD DS) improves flexibility and resilience by including easy alignment of failover cluster dependencies on AD DS, automated recovery of unintentionally removed cluster virtual computer objects (VCOs), support for cluster deployments in branch office with read-only domain controllers, and the ability for failover clusters to start without AD DS dependencies.
Cluster Quorum Management
Improvements to cluster quorum management that simplify quorum setup and increase the uptime of clusters during the failover process include a revamped quorum configuration wizard, the ability to assign which nodes have quorum votes, and the ability to automate quorum vote assignment depending on the current state of the node.
Enhancements to the Cluster Migration Wizard
The enhanced Migrate a Cluster Wizard in Windows Server 2012 simplifies the tasks of installing, updating, and migrating Windows 2008 failover clusters through improvements that include the ability to export and re-import Hyper-V VMs, migrate to Cluster Shared Volume (CSV) disks, map virtual networks and storage, and reuse current storage.
Task Scheduler Integration
Windows Server 2012 failover clustering features a new integrated Task Scheduler that makes it possible to use Windows PowerShell cmdlets to configure cluster tasks, providing a versatile tool for utilizing cluster resources to run processes or applications at set times. Tasks can be scheduled to run on a single random node, all nodes, or nodes with specified resources.
Windows PowerShell support
An enhanced Failover Cluster module for Windows PowerShell provides a library of cmdlets for automating support for the Failover Clustering features in Windows Server 2012. New cmdlets support a variety of features such as the ability to manage cluster registry checkpoints, create Scale-Out File Servers, monitor VM applications, change the properties of a Distributed Network Name resource, create and manage clustered tasks, and create a fault-tolerant iSCSI Target Server.
