Related resources are combined into a role , which can be made dependent upon other WSFC cluster resources. This type of instance depends on resources for storage and virtual network name. The virtual network name resource depends on one or more virtual IP addresses, each in a different subnet. In the event of a failover, the WSFC service transfers ownership of instance’s resources to a designated failover node. The SQL Server instance is then re-started on the failover node, and databases are recovered as usual.

At any given moment, only a single node in the cluster can host the FCI and underlying resources. The shared disk storage volumes must be available to all potential failover nodes in the WSFC cluster. An availability group consists of a primary availability replica and one to four secondary replicas that are maintained through SQL Server log-based data movement for data protection without the need for shared storage.

The availability group and a corresponding virtual network name are registered as resources in the WSFC cluster. An availability group listener on the primary replica’s node responds to incoming client requests to connect to the virtual network name, and based on attributes in the connection string, it redirects each request to the appropriate SQL Server instance.

In the event of a failover, instead of transferring ownership of shared physical resources to another node, WSFC is leveraged to reconfigure a secondary replica on another SQL Server instance to become the availability group’s primary replica. The availability group’s virtual network name resource is then transferred to that instance. At any given moment, only a single SQL Server instance may host the primary replica of an availability group’s databases, all associated secondary replicas must each reside on a separate instance, and each instance must reside on separate physical nodes.

A Failover Cluster Instance FCI may be used together with an availability group to enhance the availability of an availability replica. However, to prevent potential race conditions in the WSFC cluster, automatic failover of the availability group is not supported to or from an availability replica that is hosted on a FCI. High availability for an Always On solution is accomplished though proactive health monitoring of physical and logical WSFC cluster resources, together with automatic failover onto and re-configuration of redundant hardware.

A system administrator can also initiate a manual failover of an availability group or SQL Server instance from one node to another. These policies, based on the severity, duration, and frequency of unhealthy cluster resource status and node responsiveness, can trigger a service restart or an automatic failover of cluster resources from one node to another, or can trigger the move of an availability group primary replica from one SQL Server instance to another.

Failover of an availability group replica does not affect the underlying SQL Server instance. Failover of a FCI moves the hosted availability group replicas with the instance. Each resource in a WSFC can report its status and health, periodically or on-demand. A variety of circumstances may indicate resource failure; e. WSFC resources such as networks, storage, or services can be made dependent upon one another.

The cumulative health of a resource is determined by successively rolling up its health with the health of each of its resource dependencies. Each node in a WSFC participates in periodic heartbeat communication to share the node’s health status with the other nodes. Unresponsive nodes are considered to be in a failed state. If the WSFC has enough votes, it is healthy and able to provide node-level fault tolerance.

A quorum mode is configured in the WSFC that dictates the methodology used for quorum voting and when to perform an automatic failover or take the cluster offline. It is best practice to always have an odd number of quorum votes in a WSFC. For the purposes of quorum voting, SQL Server does not have to be installed on all nodes in the cluster. The witness, whether it is a disk witness or a file share witness, establishes quorum so the cluster can survive the failure of a node.

Note that a file share witness can be established in Azure. The way Azure billing works there is not enough usage established to a file share witness that the witness ends up not costing you anything. So if you don’t have your own source for a file share witness and don’t want to set up a disk witness, use Azure for no cost.

It doesn’t sound like you are overly concerned about running a supported configuration. If that is the case, I would not consider using the cluster in a production environment. StarWind will create Witness device for you. I’ve configured a cluster with these settings on Linux with the corosync pacemaker stack , but now I want to move on Windows The cluster will not be online so I can’t use Azure.

So I need an external HD to configure quorum. At the moment I have the virtual ip configured with no witness, I shut down one node but the other still stays on. Am I missing something? For now it’s just a testing environment, my goal was getting a cluster like the one I described with Windows Server It would be best to do it without witness like my conf in Linux , but since you said it’s mandatory I’ll have to get an external HD.

It is not recommended to run web services on a failover cluster. The recommended way to configure a web server is by using network load balancing. It used to be the IIS was available as a cluster-aware application, but engineering decided that NLB was a better solution. Therefore, if you want to cluster IIS now, you need to cluster it as a generic service. I will admit that for your environment, it does present a bit of an issue because then you would need to set up two nodes in NLB for the web server and two nodes in failover clustering for file services.

Starwind answered with a suggestion to use their free software. There are other third-party packages that offer similar capabilities, though Starwind is the one more often quoted. That would allow you to use local disks to be configured in a manner that allows them to be presented as shared, ‘external’ storage. You can then readily create the disk witness recommended for a two node cluster. Just to clear up one last thing. You talk of ” files synched across the nodes “. This actually does not happen as part of a cluster.

The failover cluster relies on access to shared storage, so there is one instance of the data that is accessed by either node. Only one node has access to the data at any point in time. Should the node that owns the access to the data fail, or its path to the data fail, the ownership of the data volume is transferred to the another node in the cluster in order to allow continued access.

If one or more cluster nodes fail, other nodes start providing service a failover process. Additionally, the clusters are under proactive monitoring to ensure that they are functioning properly. They are restarted or transferred to another node if they have issues in functioning. Cluster Shared Volume CSV is a functionality of Failover clusters that provides a consistent, distributed namespace to be used by clustered roles to access shared storage from all nodes; Users experience a minimum of disruptions in service using the Failover Clustering feature.

A failover cluster can be created either through the Failover Cluster Manager snap-in or through the Windows PowerShell. Must install the Failover Clustering feature on every server that is to be added as a failover cluster node.

Step 1: Start Server Manager. Step 3: Click Next, On the Before you begin page. Step 5: On the Select Destination Server page, select the server where you want to install the feature, and then click Next. No server restart is required for the Failover Clustering feature. Step When the installation is completed, click Close. Step Repeat this procedure on every server that you want to add as a failover cluster node.

Before we start, attach an iSCSI storage in all the nodes and make sure all virtual switches in nodes are identical. Step 4: Now browse and select the nodes and click Next.

Windows Server has made installation and configuration of failover clusters a lot easier compared to previous versions of Windows Server, making it the standard for the setup experience for later versions. Not much has changed with the installation and configuration but newer features were introduced that made Windows Server the platform of choice for providing high availability for SQL Server workloads – both for failover clustered instances and Availability Groups.

In this series of tips, you will install a SQL Server failover clustered instance on a Windows Server failover cluster the traditional way – with Active Directory-joined servers and shared storage for the SQL Server databases. Consult your systems administrators on how to perform these tasks.

It is assumed that the servers that you will join to the WSFC are already joined to an Active Directory domain and that the domain user account that you will use to perform the installation and configuration has local Administrative privileges on all of the servers. Similar to this previous tip , you need to provision your shared storage depending on your requirement. This tip assumes that the underlying shared storage has already been physically attached to all of the WSFC nodes and that the hardware meets the requirements defined in the Microsoft TechNet article Failover Clustering Hardware Requirements and Storage Options.

Managing shared storage requires an understanding of your specific storage product which is outside the scope of this tip. Consult your storage vendor for more information. The goal here is to provision shared storage both for capacity and performance.

Perform the necessary storage stress tests to make sure that you are getting the appropriate amount of IOPs as promised by your storage vendor. You can use the DiskSpd utility for this purpose. Before you can create a failover cluster, you must install the Failover Clustering feature on all servers that you want to include in the WSFC.

The Failover Clustering feature is not enabled, by default. If you plan to deploy several servers to be members of a WSFC, you can create a generic server OS deployment image that includes this feature.

This can be done by using the Sysprep utility built into the Windows Server operating system. When prompted with the Add features that are required for Failover Clustering dialog box, click Add Features. Click Next. NET Framework 3. This is no longer the case with SQL Server Next, you need to run the Failover Cluster Validation Wizard from the Failover Cluster Management console as described in this previous tip. A note on the results : In the past, the Cluster Validation Wizard may report Warning messages pertaining to network and disk configuration issues, missing security updates, incompatible drivers, etc.

The general recommendation has always been to resolve all errors and issues that the Cluster Validation Wizard reports prior to proceeding with the next steps. And it still is. Despite choosing the Run a ll tests recommended option, the Cluster Validation Wizard will exclude those checks.

This is why you will get a Warning message in the cluster validation report despite having all selected default checks return successful results.

Another way of running the Failover Cluster Validation is by using the Test-Cluster PowerShell cmdlet as described in this previous tip. In the next tip in this series, you will go thru the process of creating the WSFC and configure the cluster quorum settings using the new Windows Server failover clustering features.

Once you’ve manage to create a working Windows Server failover cluster, that’s the only time you can proceed to install SQL Server Otherwise, I do not include it. Hi, I notice distributed transaction coordinated is not included in the guide. Is it still a must for SQL cluster for windows server ? The tutorial is nice, but I need a way to automate this. I don’t want to have to access every member and run through all the GUI and wizard interfaces in order to complete the install and configuration.

The same best practices apply. It can be on the same subnet as the public NICs. However, your goal is to achieve reliability and stability. If you use the same network as the public NICs, the heartbeat communication will end up going thru the same traffic as everything else. Even if the roads are wide, you end up being stuck in traffic if they are congested, regardless of the size of the vehicle.

This will affect the overall availability of your cluster. Hence, I still recommend having a dedicated NIC for the internal cluster communication. I don’t see any information on settings for the NICs?? Do we still need a HeartBeat? Can it be on the same subnet as pubic addresses? View all my tips. Recommended Reading.

Applies to: SQL Server all supported versions. Cluster resource A physical or logical entity that can be owned by a node, brought online and taken offline, moved between nodes, and managed as a cluster object. A cluster resource can be owned by only a single node at any point in time. Role A collection of cluster resources managed as a single cluster object to provide specific functionality. Failover and failback always act in context of roles. Network name resource A logical server name that is managed as a cluster resource.

A network name resource must be used with an IP address resource. Resource dependency A resource on which another resource depends. If resource A depends on resource B, then B is a dependency of A. Resource A will not be able to start without resource B. Preferred owner A node on which a resource group prefers to run. Each resource group is associated with a list of preferred owners sorted in order of preference.

During automatic failover, the resource group is moved to the next preferred node in the preferred owner list. Possible owner A secondary node on which a resource can run. Each resource group is associated with a list of possible owners. Roles can fail over only to nodes that are listed as possible owners. Quorum mode The quorum configuration in a failover cluster that determines the number of node failures that the cluster can sustain.

Force quorum The process to start the cluster even though only a minority of the elements that are required for quorum are in communication.

Windows Server Failover Clustering provides infrastructure features that support the high-availability and disaster recovery scenarios of hosted server applications such as Microsoft SQL Server and Microsoft Exchange.

If a cluster node or service fails, the services that were hosted on that node can be automatically or manually transferred to another available node in a process known as failover. Distributed metadata and notifications. WSFC service and hosted application metadata is maintained on each node in the cluster. This metadata includes WSFC configuration and status in addition to hosted application settings.

Changes to a node’s metadata or status are automatically propagated to the other nodes in the WSFC. Resource management. Individual nodes in the WSFC may provide physical resources such as direct-attached storage, network interfaces, and access to shared disk storage.

Hosted applications register themselves as a cluster resource, and may configure startup and health dependencies upon other resources. Health monitoring. Inter-node and primary node health detection is accomplished through a combination of heartbeat-style network communications and resource monitoring. Failover coordination. Each resource is configured to be hosted on a primary node, and each can be automatically or manually transferred to one or more secondary nodes. A health-based failover policy controls automatic transfer of resource ownership between nodes.

Nodes and hosted applications are notified when failover occurs so that they may react appropriately. The Always On features provide integrated, flexible solutions that increase application availability, provide better returns on hardware investments, and simplify high availability deployment and management. Related resources are combined into a role , which can be made dependent upon other WSFC cluster resources.

This type of instance depends on resources for storage and virtual network name. The virtual network name resource depends on one or more virtual IP addresses, each in a different subnet. In the event of a failover, the WSFC service transfers ownership of instance’s resources to a designated failover node.

The SQL Server instance is then re-started on the failover node, and databases are recovered as usual. At any given moment, only a single node in the cluster can host the FCI and underlying resources. The shared disk storage volumes must be available to all potential failover nodes in the WSFC cluster.

An availability group consists of a primary availability replica and one to four secondary replicas that are maintained through SQL Server log-based data movement for data protection without the need for shared storage. The availability group and a corresponding virtual network name are registered as resources in the WSFC cluster.

An availability group listener on the primary replica’s node responds to incoming client requests to connect to the virtual network name, and based on attributes in the connection string, it redirects each request to the appropriate SQL Server instance. In the event of a failover, instead of transferring ownership of shared physical resources to another node, WSFC is leveraged to reconfigure a secondary replica on another SQL Server instance to become the availability group’s primary replica.

The availability group’s virtual network name resource is then transferred to that instance. At any given moment, only a single SQL Server instance may host the primary replica of an availability group’s databases, all associated secondary replicas must each reside on a separate instance, and each instance must reside on separate physical nodes. A Failover Cluster Instance FCI may be used together with an availability group to enhance the availability of an availability replica.

However, to prevent potential race conditions in the WSFC cluster, automatic failover of the availability group is not supported to or from an availability replica that is hosted on a FCI.

A quorum mode is configured in the WSFC that dictates the methodology used for quorum voting and when to perform an automatic failover or take the cluster offline. It is best practice to always have an odd number of quorum votes in a WSFC. For the purposes of quorum voting, SQL Server does not have to be installed on all nodes in the cluster.

An additional server can act as a quorum member, or the WSFC quorum model can be configured to use a remote file share as a tie-breaker. Depending upon operational practices and WSFC configuration, you can incur both automatic and manual failovers, and still maintain a robust, fault-tolerant SQL Server Always On solution. If the WSFC goes offline because of an unplanned disaster, or due to a persistent hardware or communications failure, then manual administrative intervention is required to force quorum and bring the surviving cluster nodes back online in a non-fault-tolerant configuration.

Afterwards, a series of steps must also be taken to reconfigure the WSFC, recover the affected database replicas, and to re-establish a new quorum. A client request that specifies a logical availability group listener network name to connect to a primary or secondary database is redirected to the appropriate instance network name of the underlying SQL Server instance or SQL Server FCI. SQL Server instances are actively hosted on a single node. Nodes are members of a WSFC cluster. WSFC configuration metadata and status for all nodes is stored on each node.

Each server may provide asymmetric storage or shared storage SAN volumes for user or system databases. Each server has at least one physical network interface on one or more IP subnets.

The WSFC monitors health and manages configuration for a group of servers. If a disk witness is used, the metadata is also stored there. By default, each node of the WSFC gets a vote towards quorum and a witness will be used if necessary and is configured.

A failover cluster is a group of independent computers that work together to increase the availability and scalability of clustered roles formerly called clustered applications and services. The clustered servers called nodes are connected by physical cables and by software. If one or more of the cluster nodes fail, other nodes begin to provide service a process known as failover.

In addition, the clustered roles are proactively monitored to verify that they are working properly. If they are not working, they are restarted or moved to another node. Failover clusters also provide Cluster Shared Volume CSV functionality that provides a consistent, distributed namespace that clustered roles can use to access shared storage from all nodes.

I’d like to create a 2 node cluster with 2 servers with Windows Server Standard. My cluster should be in active-passive configuration without Active Directory.

Do I have to configure a witness external disk since the number of nodes is even? Is there a way to avoid that? Yes, you can create a cluster without active directory. You should have a disk witness or a file share witness. Either one will work. Without a witness, loss of either node will bring down the cluster due to lack of quorum.

I have a concern about the wording of your question. You call the witness disk an external disk. It cannot use internal storage. If you want to use internal storage, you will need to use a third party tool that presents the internal storage as ‘external’ storage.

If you want to use only internal storage, Microsoft has the ability to create a Storage Spaces Direct S2D cluster, but that is a feature that is unique to Windows Server Datacenter. It is not available in Standard. The hardware also has more strict requirements than that required for a regular failover cluster that uses external, shared storage. If you plan to go that route, it is recommended that you work with a system vendor that has a solution that has been WSSD certified to ensure all the components have been certified and tested to work together.

It is also recommended to have a Premier support contract in place. I’ve looked into the link you posted and it seems it’s what I am looking for since I don’t have active directory on the two nodes. If I have to create a witness without third party tools budget reasons what would you advice? Is there a step-by-step guide?

File replication is not a feature of clustering. There is a storage replication feature in Windows that can replicate volumes between clusters for a disaster recovery solution, but it doesn’t sound like that is what you are looking for. Could you please explain what you mean by “file replication”? This sounds like two separate questions. Is storage mandatory? Is witness mandatory? No, but if you have just two nodes, that means that failure of either node brings down the entire cluster.

The witness, whether it is a disk witness or a file share witness, establishes quorum so the cluster can survive the failure of a node. Note that a file share witness can be established in Azure.

The way Azure billing works there is not enough usage established to a file share witness that the witness ends up not costing you anything. So if you don’t have your own source for a file share witness and don’t want to set up a disk witness, use Azure for no cost. It doesn’t sound like you are overly concerned about running a supported configuration. If that is the case, I would not consider using the cluster in a production environment.

StarWind will create Witness device for you. I’ve configured a cluster with these settings on Linux with the corosync pacemaker stack , but now I want to move on Windows The cluster will not be online so I can’t use Azure. So I need an external HD to configure quorum. At the moment I have the virtual ip configured with no witness, I shut down one node but the other still stays on.

Am I missing something? For now it’s just a testing environment, my goal was getting a cluster like the one I described with Windows Server It would be best to do it without witness like my conf in Linux , but since you said it’s mandatory I’ll have to get an external HD. It is not recommended to run web services on a failover cluster. The recommended way to configure a web server is by using network load balancing.

It used to be the IIS was available as a cluster-aware application, but engineering decided that NLB was a better solution. Therefore, if you want to cluster IIS now, you need to cluster it as a generic service.

I will admit that for your environment, it does present a bit of an issue because then you would need to set up two nodes in NLB for the web server and two nodes in failover clustering for file services. Starwind answered with a suggestion to use their free software. There are other third-party packages that offer similar capabilities, though Starwind is the one more often quoted.

That would allow you to use local disks to be configured in a manner that allows them to be presented as shared, ‘external’ storage. You can then readily create the disk witness recommended for a two node cluster. Just to clear up one last thing. You talk of ” files synched across the nodes “. This actually does not happen as part of a cluster. The failover cluster relies on access to shared storage, so there is one instance of the data that is accessed by either node.

Only one node has access to the data at any point in time. Should the node that owns the access to the data fail, or its path to the data fail, the ownership of the data volume is transferred to the another node in the cluster in order to allow continued access. The cluster guarantees access to the data, but it has no synchronization feature.

A new type of quorum witness that leverages Microsoft Azure to determine which cluster node should be authoritative if a node goes offline. Improves the day-to-day monitoring, operations, and maintenance experience of Storage Spaces Direct clusters.

Helps to define which fault domain to use with a Storage Spaces Direct cluster. A fault domain is a set of hardware that shares a single point of failures, such as a server node, server chassis or rack. The load is distributed across nodes evenly with its help, in a Failover Cluster by finding out busy nodes and live-migrating VMs on these nodes to less busy nodes. Windows Server breaks down the previous barrier of creating cluster between the member nodes joined to the same domain and introduces the ability to create a Failover Cluster without Active Directory dependencies.

The following configuration is implemented in Failover Clusters can now, be created in:. It cannot use internal storage. If you want to use internal storage, you will need to use a third party tool that presents the internal storage as ‘external’ storage.

Role A collection of cluster resources managed as a single cluster object to provide specific functionality. Failover and failback always act in context of roles. Network name resource A logical server name that is managed as a cluster resource.

A network name resource must be used with an IP address resource. Resource dependency A resource on which another resource depends. If resource A depends on resource B, then B is a dependency of A. Resource A will not be able to start without resource B.

Preferred owner A node on which a resource group prefers to run. Each resource group is associated with a list of preferred owners sorted in order of preference. During automatic failover, the resource group is moved to the next preferred node in the preferred owner list. Possible owner A secondary node on which a resource can run. Each resource group is associated with a list of possible owners. Roles can fail over only to nodes that are listed as possible owners.

Quorum mode The quorum configuration in a failover cluster that determines the number of node failures that the cluster can sustain. Force quorum The process to start the cluster even though only a minority of the elements that are required for quorum are in communication. Windows Server Failover Clustering provides infrastructure features that support the high-availability and disaster recovery scenarios of hosted server applications such as Microsoft SQL Server and Microsoft Exchange.

If a cluster node or service fails, the services that were hosted on that node can be automatically or manually transferred to another available node in a process known as failover. Distributed metadata and notifications. WSFC service and hosted application metadata is maintained on each node in the cluster. This metadata includes WSFC configuration and status in addition to hosted application settings. Changes to a node’s metadata or status are automatically propagated to the other nodes in the WSFC.

It is best practice to always have an odd number of quorum votes in a WSFC. For the purposes of quorum voting, SQL Server does not have to be installed on all nodes in the cluster. An additional server can act as a quorum member, or the WSFC quorum model can be configured to use a remote file share as a tie-breaker.

Depending upon operational practices and WSFC configuration, you can incur both automatic and manual failovers, and still maintain a robust, fault-tolerant SQL Server Always On solution. If the WSFC goes offline because of an unplanned disaster, or due to a persistent hardware or communications failure, then manual administrative intervention is required to force quorum and bring the surviving cluster nodes back online in a non-fault-tolerant configuration.

Afterwards, a series of steps must also be taken to reconfigure the WSFC, recover the affected database replicas, and to re-establish a new quorum. A client request that specifies a logical availability group listener network name to connect to a primary or secondary database is redirected to the appropriate instance network name of the underlying SQL Server instance or SQL Server FCI. SQL Server instances are actively hosted on a single node.

Nodes are members of a WSFC cluster. WSFC configuration metadata and status for all nodes is stored on each node. Each server may provide asymmetric storage or shared storage SAN volumes for user or system databases.

Each server has at least one physical network interface on one or more IP subnets. The WSFC monitors health and manages configuration for a group of servers. If a disk witness is used, the metadata is also stored there. By default, each node of the WSFC gets a vote towards quorum and a witness will be used if necessary and is configured.
