Disaster Recovery/Business Continuity Consulting Support for
Windows Server 2016 Failover Clusters:
Planning, Deployment, Management and Troubleshooting
Windows Server 2016 Datacenter Edition includes significant enhancements to Failover Clustering, a key technology that supports disaster recovery (DR) and high availability by allowing you to combine multiple servers to form a fault-tolerant cluster on physical hardware or in virtual machines. A major enhancement is Storage Replica, Microsoft's first native solution for zero-data-loss disaster recovery, Storage Replica allows organizations to configure separate sites within a metro area to mirror data with crash-consistent volumes in order to ensure full data recovery in the event of a site outage. Windows Server 2016 includes a number of other important new and enhanced features for Failover Clusters, offering significant benefits in areas including availability and fault tolerance, Hyper-V virtualization, storage and infrastructure costs, ease of deployment, manageability, security, scale, performance, hybrid cloud support, health monitoring and audit reporting.
Windows Server 2016 is a cloud-tested platform that takes technology proven in Microsoft's vast Azure public cloud, including Azure's software-defined data plane, and makes it available for on premises deployments. As hybrid networks have become the norm, the migration of cloud technology to private data centers has made enterprise-class disaster recovery solutions practical for organizations of virtually any size.
Progent's team of disaster recovery consultants and certified Windows Server experts have the knowledge and experience to help you plan, deploy, test, maintain and troubleshoot a disaster recovery solution based on Windows Server 2016 that aligns with your business goals and IT budget. Progent's information assurance experts can help you prove compliance with regulatory requirements for disaster recovery, and Progent's business continuity consultants can help you integrate your disaster recovery strategy into a broader plan to keep your business operating at an acceptable level in the event of a predictable widespread catastrophe. By showing you practical and affordable ways to deploy Windows Server 2016 to improve your Recovery Point Objective (RPO) and Recovery Time Objective (RTO), Progent can help ensure that your investment in current disaster recovery and clustering technology adds maximum business value to your information network.
Windows Server 2016 Storage Replica
The headline disaster recovery feature of Windows Server 2016 is Storage Replica, Microsoft's first foray into zero-data-loss DR. Storage Replica allows you to mirror data between sites located within metro distances by using synchronous replication over a low-latency (5 ms or better round trip) TCP/IP or RDMA network using an SMB3 transport. If a protected site (also called a source or primary site) suffers a complete shutdown, you can switch quickly to the recovery site (also called destination or secondary site) without losing any data written to disk storage. Storage Replica can also be used for disaster avoidance, where users are seamlessly switched over to a recovery site in expectation of an imminent catastrophe such as a flood, wildfire or hurricane. For sites separated by longer distances or otherwise subject to higher latencies, Storage Replica supports an asynchronous replication mode that provides minimal data loss.
Storage Replica uses block-level replication between clusters or servers. This means that protected applications write data to at least two locations before the completion of any write operation. Because Storage Replica operates below the file level, it avoids the restrictions of technologies like DFS Replication, which requires that files be closed before replication and is subject to issues like files locks and open handles. Progent can help you upgrade from low-end disaster recovery solutions like DFS Replication to a zero-data-loss DR solution based on Windows Server 2016 Storage Replica.
For higher latency networks that span longer distances, Storage Replica supports asynchronous replication. Since Storage Replica asynchronous replication is continuous, not checkpoint based, the amount of data at risk of being lost is far lower than DR solutions based on snapshots. In addition, Storage Replica works at the partition layer, so it replicates all Volume Shadow Copy Service (VSS) snapshots, allowing application-consistent data snapshots for point-in-time recovery.
Storage Replica allows replication between clusters with zero data loss at the file-system level
Topologies supported by Storage Replica include stretch clusters, cluster-to-cluster, and server-to-server. These configurations can run on physical hardware or VMs based on Hyper-V, VMware, Citrix XenServer, or other leading virtualization platforms. Stretch cluster configurations allow you to orchestrate and automate the failover process for workloads like Hyper-V private cloud clusters and SQL Server Failover Cluster Instance (FCI) and can be managed with Failover Cluster Manager. Storage Replica with stretched clusters can use Storage Spaces, SAN, iSCSI, and RAID through persistent reservation and can be run with two or more nodes.
The cluster-to-cluster configuration utilizes uses two distinct clusters and allows administrators to control the failover process manually. This topology is suited for environments where the secondary site set up solely for disaster recovery rather than as an active data center. With a cluster-to-cluster configuration, Storage Replica supports the cost-saving Storage Spaces feature of Windows Server 2016 and can be run with four or more nodes.
If your hardware does not support clustering, you can run Storage Replica in a server-to-server configuration. In this case the failover process must be performed manually. This can be a cost-effective DR solution between branch offices and data centers, and with asynchronous replication can support significantly better RPO than can be achieved with DFS Replication.
Progent can help you determine which Storage Replica topology makes the most sense for you business and can also help you plan, deploy, manage and troubleshoot your Storage Replica solution. For other zero-data-loss disaster recovery platforms supported by Progent, see VMware Site Recovery Manager consulting and NetApp MetroCluster disaster recovery consulting.
Additional Features of Windows Server 2016 for Failover Clustering
Important new and enhanced features of Windows Server 2016 include:
How Progent Can Help You with Windows Server 2016 Disaster Recovery
- Storage Spaces Direct allows you to pool low-cost commodity servers running Windows Server 2016 to create network attached failover storage clusters. The rotating and solid-state disks (SSDs) integrated with each server are automatically onboarded to the Failover Cluster by Storage Spaces Direct (S2D), and you can combine as many as 16 servers and 400 drives for up to 1 petabyte of storage per cluster. New servers can be added in minutes, and with Microsoft System Center require only a checkbox to install. The scale-out servers use their built-in Ethernet RDMA controllers and Microsoft's SMB3 transport to interconnect, eliminating the expense and management overhead associated with deploying a SAN solution with FC fabric.
When you create volumes from the storage pool, Storage Spaces Direct automatically generates a virtual disk and takes care of partitioning, formatting, and adding it to your Failover Cluster so it can be accessed by any node as a CSV. These shared volumes can tolerate drive, server, or component failures with uninterrupted availability, and you can replace failed hardware without downtime or complex management intervention. Performance can exceed 150,000 mixed random IOPS per server thanks to an integrated read/write cache and support for NVMe drives mounted directly on the PCIe bus. Storage Spaces Direct automatically utilizes the fastest storage available, such as SSDs, for its always-on cache.
Hyper-converged deployments of Storage Spaces Direct are a good fit for SMBs or branch offices
System Center 2016 Virtual Machine Manager supports two models for configuring and managing Storage Spaces Direct clusters. In a converged deployment, also called disaggregated, compute and storage resources run on different clusters. This provides administrators with the flexibility to scale compute resources independently from storage and is suitable for enterprises with larger environments and the skills to manage complex deployments. With a hyper-converged deployment model, Hyper-V compute and storage share the same cluster. This model, which minimizes hardware costs and is easier to configure and manage, is appropriate for smaller organizations or branch offices.
- Health Service is a feature introduced in Windows Server 2016 for monitoring the performance and capacity of Storage Spaces Direct clusters. Metrics reported by Health Service include IOPS, IO throughput and latency, physical (raw) storage and storage pool capacity, volume capacity, processor utilization, and memory. Health Service also continually monitors Storage Spaces Direct clusters and generates fault alerts ranked by severity and covering cluster and storage hardware, the Storage Spaces software stack, storage Quality of Service, and Storage Replica. For conciseness, fault alerts report root causes, such as a failed enclosure, rather than all the components affected by the failure.
Health Service can automate workflows in the disk retirement/replacement cycle by reporting a failed disk, copying data from the retired disk to the remaining disks to restore full resiliency, indicating a failed disk by blinking its disk or slot indicator light, verifying a replacement disk against a Supported Components Document, and substituting the replacement disk into the storage pool previously occupied by the retired disk.
- Cluster Operating System Rolling Upgrade is a new feature of Windows Server 2016 that allows the live migration of all virtual machines in a cluster from a Windows Server 2012 R2 host to Windows Server 2016 host. This lets you move Hyper-V and scale-out file server workloads to the latest version of Windows Server with zero interruption of service, avoiding downtime penalties against SLAs. Other cluster workloads like SQL Server are paused only for the few minutes required to failover to Windows Server 2016. The rolling upgrade process requires no extra hardware and the upgraded cluster continues using the existing cluster objects stored in Active Directory.
Cluster Operating System Rolling Upgrade utilizes a new mixed-OS mode that allows nodes with different host operating system versions to run within the same cluster. This allows you to pause, drain, evict, and reformat any node in the cluster, install Windows Server 2016 on the node, and bring the node back online. The Failover Cluster continues operating during this procedure as it would during any node outage. You can then use Failover Cluster Manager or PowerShell to add the upgraded node back into the cluster. All nodes operate at the older Windows Server 2012 R2 functional level until every node in the cluster has been upgraded. When all nodes have been migrated to Windows Server 2016, the entire cluster can be upgraded at once to the new functionality level with a single PowerShell cmdlet.
Rolling Upgrades allow you to stage a migration to Windows Server 2016 VMs without incurring cluster downtime
Progent can guide you through the Cluster Operating System Rolling Upgrade process following best practices, help you load balance the upgraded cluster, and show you how to take advantage of the new features provided by Windows Server 2016.
- Fault Domains are hardware entities that share a single point of failure. Servers, or nodes, are the original fault domain supported by Windows Server Failover Clustering. Windows Server 2016 adds support for fault domains at the chassis, rack and site levels. Fault domain awareness improves fault tolerance by helping to distribute data across multiple vulnerable components so copies of protected data reside in different fault domains. Windows Server 2016 allows you to define fault domains with PowerShell or XML markup. Storage Spaces Direct uses fault domains to optimize data protection by automatically placing copies of data on different drives, nodes, chasses and racks. Windows Server 2016 Health Service uses fault domains to improve the usefulness of alerts. Stretch clustering uses fault domains for storage affinity, improving performance by running applications or VMs on servers in closest proximity to their storage servers.
- Virtual Machine Load Balancing is a new integrated feature of Windows Server 2016 that allows automatic live migration of virtual machines between nodes within a Failover Cluster. This helps maximize availability and performance of Failover Clusters and reduces the need to deploy additional physical servers to handle critical workloads during peak periods. VM Load Balancing improves performance, fault tolerance and resource utilization by automatically determining whether a node has become overloaded and assigning VMs from that node to an under-committed one, such as a server that has just been rebooted. This process requires no downtime, takes into account failure policies like fault domains, and is based on heuristics for weighing VM memory pressure, which is the most common resource constraint on a Hyper-V host, and CPU utilization of the node. VM Load Balancing can be configured to run every 30 minutes or on demand, and you can use PowerShell to select one of three thresholds for determining the aggressiveness of load balancing.
VM Load Balancing automatically and non-disruptively moves VMs from over-utilized to under-utilized nodes
- Virtual Machine Start Order is a new feature in Windows Server 2016 Failover Clustering that allows you to orchestrate the priority in which VMs and all groups in a cluster are activated or re-activated. You can group VMs into tiers and define dependencies between different tiers. This can ensure, for example, that VM domain controllers are started first. This avoids scenarios where VMs that require services are activated before the VMs that deliver those services.
- Cloud Witness is a new type of quorum witness for Windows Server 2016 Failover Clusters that uses Microsoft Azure Blob Storage to maintain a blob file to act as the quorum arbitration point. The quorum witness has a vote in determining whether to keep a stretch cluster running after a datacenter experiences an outage and is an important component of an enterprise-class disaster recovery solution. Leveraging the Microsoft Azure cloud infrastructure is an easy and affordable way to host an offsite quorum witness without the cost and management overhead of deploying a separate datacenter. This also adheres to best practices when designing the topology of a quorum witness. You can use a single Azure Storage Account for multiple clusters, with one blob file required for each cluster. Since only a small amount of data is written to the blob file, which is updated only when the state of the cluster nodes change, the ongoing costs of the Azure storage account is low.
Azure-based Cloud Witness is a fast, affordable way to configure a Failover Cluster quorum witness
- Support for Workgroup and Multi-domain Clusters makes it possible to create Windows Server 2016 Failover Clusters without Active Directory dependencies. In previous releases of Windows Server, Failover Clusters could only be created with server nodes joined to the same domain. Windows Server 2016 still lets you create single-domain clusters but you can also deploy Workgroup clusters and Multi-domain clusters with nodes that are members of different domains. You can use Failover Cluster Manager or PowerShell to create Workgroup clusters and Multi-domain clusters. The recommended witness type for Workgroup clusters and Multi-domain clusters is Disk Witness or the new Windows Server 2016 Cloud Witness. File Share Witness is unsupported for clusters with nodes that are not domain joined.
