Use Cases and Deployment Scope

We use Windows Server Failover Clustering as a solution for high availability for many porpouses: Virtual Machines, Network File Sharing and SQL Server Instances. We have dedicated clusters for Virtual Machines and Network File Share, and another one for SQL Server Instances. For the Virtual Machines, we use the live migration feature to put a node in maintence mode, without take any Virtual Machine off.

Pros

Virtual Machines live migration
Network File Share
SQL Server Failover Cluster Instances
DHCP Service
File Server

Cons

Support for windows services appplications
Disk management
Other Windows forms applications

Likelihood to Recommend

For Windows nativilly applications, for Windows server roles and features with need for high availability, file shares and file servers, virtual machines high availability, network services such as DHCP and WINS, DFS Namespaces, and other applications that required high availability, once they have an executable and network address. It only needs a Windows Server License to work.

Windows Server Failover Clustering

Rating: 10 out of 10

January 7, 2025

Use Cases and Deployment Scope

I use Windows Server Failover Clustering primarily in hyperv clusters with physical servers but also in some cases in hyperv clusters with virtual servers (nested virtualization in lab environments). Also i use Windows Server Failover Clustering in SQL Server virtual clustering (guest clustering). The major business problems addressed are high availability and agility in hosting business workloads in a reliable manner.

Pros

HyperV live migration
HyperV storage migration
Virtual machine failover

Cons

Cluster-aware updating seems to not be consistent in all cases
Hardware supportability matrix can be expanded to cover more hardware
Some specialized use cases can only be carried out via Powershell only

Likelihood to Recommend

Hosting a HyperV cluster is the best use case for a Windows Server Failover Clustering When hosting other types of workloads, Windows Server Failover Clustering may not be the most cutting edge technology available, such as in the case of SQL Server clustering, where SQL Always On Availability groups is the recommended method.

Use Cases and Deployment Scope

We utilized Windows Server Failover Clustering as an integral part of a MS SQL cluster setup. We utilized it for almost zero downtime on our Microsoft SQL serving our on prem Sharepoint implementations, as well as several critical IT infrastructure systems that need a SQL database back end. This allows us to perform maintenance and patching without affecting the applications that use the SQL server. It's deployed on a active passive setup. We also set up a test Hyper-V high availability cluster.

Pros

It allows us to perform maintenance and patching on the passive node without having to shutdown the database and incurring downtime.
We are able to repair a failed server but failing the database over if there is a hardware failure on the active node. Minimizing downtime on the database.
It provides an automated recovery when there is failure without IT intervention when there is an issue.

Cons

The setup of the Windows Server Failover Clustering is complex, requiring different networks and multiple network cards.
Better integration between the Windows Failover clustering and Hyper-V. Unlike VMWare you have to make changes to two places instead of just one panel.
I wish there was a web portal to manage the cluster. Instead you have to remote desktop into the VIP address and go to the Cluster manager.

Likelihood to Recommend

It works fantastic in conjuncture with the MS SQL cluster setup. When a SQL node had a hardware failure, it failed over to the passive node. No one was the wiser that anything happened to the system until our Operations department realized that node was down. We were able to repair the server and bring it back up without causing issues on the database. Which meant the application was also still up, which we were very happy with. I didn't like it when used with Hyper-V to setup a cluster, although it allowed us to set it up similar to a VMWare cluster, I did not like having to go between the Windows Failover Clustering manager then the Hyper-V manager to work on a VM. It also caused a small issue when one of my colleagues setup a VM, he forgot to add Windows Failover Cluster.

Use Cases and Deployment Scope

We are currently using Windows Server Failover Clustering to serve our Microsoft Hyper-V cluster. The cluster runs our production environment comprising of email services, file services, database services, remote access, and more. All Microsoft Hyper-V roles are clustered and their storage is also managed by the cluster. It is currently running in a two node environment.

Pros

Easy to use
Out of the box
Documentation is readily available

Cons

Include storage spaces as part of the same feature set along with storage tiering

Likelihood to Recommend

Windows Server Failover Clustering is very well suited for any environment. From a one man IT shop to a business run by a large support team. It can provide easy failover between its nodes. Especially in the case of schedule maintenance on a Hyper-V node, all you need to do is ensure all roles are drained and moved to another node along with storage.

Use Cases and Deployment Scope

We have Hyper-V implemented as our primary hypervisor and we have also implemented failover clustering with cluster storage and multipath IO to mitigate node failure without impacting our work loads, in case of cluster node failure it seamlessly migrates workloads to other hypervisors without any downtime, the other benefit is that when we are updating hypervisors we live migrate virtual machines to different nodes in same cluster and restart one by one that results in no downtime and hassle free operation. it simply made management of virtual machines simpler and improved overall uptime of our infrastructure.

Pros

Seamless Live Migrations
Quick Migrations
Failover in case of Node Failure
Storage Migration

Cons

Shared nothing live migration need some improvements.
Cluster events are not very understandable.
Cluster validation.

Likelihood to Recommend

I have observed while moving multiple virtual machines failover cluster starts slowing down, so we move a maximum of two live migrations at a time, but quick migration is far faster. We used it for replicas and noncritical workloads. Windows Server Failover Clustering is very well suited for small to medium-sized organizations, i.e. its good for a few hundred virtual machines. The features present in failover clustering are getting better with each iteration.

July 26, 2021

Use Cases and Deployment Scope

We have Setup Windows Server Failover Clustering for our SQL Server Always On so that our databases are configured on Failover mode. In case any of our servers failing to respond this service will move our databases from the primary server to the disaster recovery server. Our Information technology department uses it and the user across the organization is not aware of what we have deployed or what is our architecture.

Pros

Failover Priority setting , i.e. High, medium , low.
online services movement.
Online data movement across clusters.
No downtime,
Easy role movement

Cons

Quorum settings should be improved
San environment should be improved
Logging of Cluster events should be improved

Likelihood to Recommend

SQL Server in always-on mode is the best suitable for windows server failover clustering rather than configuring the SQL Server in cluster mode having the same disk and the disk will be moved with all databases, alwaysOn is the best and suitable way to configure it on Failover Clustering as we have two separate disks and database files on the separate servers.

The Best Failover For Anything That Failovers

Rating: 10 out of 10

June 29, 2021

Use Cases and Deployment Scope

It is the backbone of our IT Infrastructure, It provides high availability of the servers to meet our business requirements, we are using it for failover solution of our exchange servers and database servers, Microsoft is working hard to making it better day by day and with the newer version 2019 we can failover to a cloud or on premises both.

Pros

It is reliable, its fast, it is the best you would not even know that you have been switched to other node.
Clustering based on geographic distribution
Multiple server multiple site deployment

Cons

Configuration could make easier
[I feel] pricing should be considered for middle size organizations to adapt it
Storage pool and VDM configuration is confusing [in my experience]

Likelihood to Recommend

Best for organizations that require 24 hours of enabled IT infrastructure to support business needs so incase of any updating activity or a disaster the user won't even know what had happened at the back and ensure smooth operations. Hot plug scalable storage is a good option for organizations using RDBMS and thin clients as well.

Windows Server Failover Clustering never fails to fail over.

Rating: 8 out of 10

March 7, 2020

Use Cases and Deployment Scope

At our organization, we use Windows Server Failover Clustering to keep our Azure DevOps Server environment in a high-availability state for our end users. Both the application tier and the SQL tier are clustered so that if there is a network fault or outage, the system will fail-over to the other server node, and the user can continue to work without knowing the server was down.

Pros

Works great with SQL Server clustering
Highly configurable, but simple and intuitive
Cluster events are shown in the tool (No need to go to the Windows Event Logs)

Cons

Would be nice if the tool had built-in alerts for when a fail-over occurred
Only one network card on a node in the same network

Likelihood to Recommend

Windows Server Failover Clustering is well suited for organizations that need to have systems running in a high-availability mode. If there are systems that would pose a high cost to the business if there is downtime due to unplanned events, then Windows Server Failover Clustering will help assure 24/7 uptime. Also, clustering can be helpful for planned events, such as server updates. You can install an upgrade on the inactive node and then fail-over manually, switching the active and inactive nodes, upgrade the other node, and then failback. Also, while I don't have direct experience with this aspect, my understanding is that Windows Server Failover Clustering is also well suited for load balancing VMs.

Use Cases and Deployment Scope

We use failover clustering to provide an active-passive failover for VMs hosted on 2 physical servers. The VMs server both are public-facing websites and our internal CRM so completely mission-critical to the entire business for continuity. This gives us the redundancy and the ability to keep things going when constantly updating windows! WFC has some very advanced features but our needs are fairly simple and this works really well for us.

Pros

Redundancy - We can spead the VMs that we use across 2 physical servers, but should one go down it all switches to the working one.
Spread the load - We can assign preferred servers for the VMs to run on so when they are available the VMs can be set to run on specific hardware.

Cons

Has a pretty steep learning curve.
Can be a lot of hoops to jump through to get up and running.
Easy to missing settings buried in the GUI.

Likelihood to Recommend

For us it's a no brainer, we're a Microsoft tech house so to have a couple of physical boxes to spread the load and provide redundancy it the only way to go. Included in the OS so it makes sense to make use of it.

Use Cases and Deployment Scope

We use Windows Server Failover Clustering for our Hyper-V environment to improve the availability of the VMs. The most important problem addressed by Failover Clustering is the reduction of the downtime for server maintenance. Standalone Hyper-V hypervisors tend to need a lot of downtime for Windows updates. The entire organization uses VMs running on top of the Failover Cluster. We use a hyper-converged solution with Failover Clustering to avoid the need to purchase expensive SANs, so the cost of improved uptime is relatively low.

Pros

Reduced outages for server maintenance. VMs can be live migrated from the node being taken down for maintenance to avoid outages. With Cluster-Aware Updating (CAU) it is possible to run Windows Update on cluster nodes automatically.
Very fast live migration and failover. With hyper-converged DAS, live migration is so fast, it is hard to see the VM outage in the RDP session.
Inexpensive. Failover Clustering is included in Windows Server. For educational organization, Windows Server licenses are extremely cheap.

Cons

iSCSI configuration can be confusing. To achieve redundancy, each node in the cluster must have redundant (multi-path) access to storage (iSCSI, FiberChannel, etc.). Configuring iSCSI multi-path correctly can take several tries.
The configuration is time-consuming. Cluster Validation Wizard is verbose - takes a while to read through and check all the issues. It is still very important to go through all of the information though. It is easy to configure a cluster that seems fine but does not failover when needed.
Not really a drawback but the effort must be made to understand quorum configuration if a cluster has even number of nodes. I would suggest doing multiple failover tests before using the cluster for production, including pulling power cables from nodes and disconnecting network cables to simulate switch failure.

Likelihood to Recommend

Windows Failover Clustering is a good fit for a medium to a large organization with a predominantly Windows Server environment. VMware and Linux shops have their own clustering options. A cost-benefit analysis should be used before deploying a cluster, as extra capacity for failover is an additional expense. As servers are quite reliable, stand-alone hypervisors can be a better fit for a small business, which can tolerate outages for maintenance. While Failover Clustering feature itself is included in the Windows Server license, cost of extra servers and especially SANs (if used) is significant. The organization must calculate whether reduced downtime is worth the expense, especially considering that clustering by itself does not guarantee high availability.
